PR0616171000DEN iv SECTION 1 Document Overview

This document provides detailed methods and typical drawings of closure methods that will be used to close or seal historic mine openings (HMOs) on Bureau of Land Management (BLM)-administered lands in Utah and Colorado. The document also provides material-specification information. Freeport Minerals Corporation (Freeport) or its contractors will complete the work described in this document. The work described in this document consists of closing HMOs by installing polyurethane foam (PUF), backfill, fencing, and wire rope nets within adits, inclines, declines, or shafts. Work includes clearing and grubbing, excavation of loose materials, trimming of openings, furnishing and securing the closure materials, and placing signage and monuments. Closure materials and specifications are generally consistent with the Colorado Department of Natural Resources Division of Mining, Reclamation, and Safety General Bid Specifications Handbook, published March 2009, and the Utah Abandoned Mine Reclamation Program’s “boilerplate” construction contract specifications published February 2011. All work conducted will be executed in accordance with the Proposed Action and National Environmental Policy Act of 1969 Categorical Exclusion that is specific to each project and approved by BLM.

PR0616171000DEN 1 SECTION 2 Introduction

Historic mine openings (HMOs) represent adits, shafts, trenches, inclines, declines, glory holes, or any other distinct identifiable feature that was used to excavate materials for mining, is no longer in use, and will not be used to excavate or mine materials soon. The following sections describe the five primary approaches used to permanently close HMOs: • Section 3: Solid PUF plug with or without a bat gate • Section 4: Wire rope netting • Section 5: Fencing • Section 6: Backfilling All materials will be prefabricated offsite, brought to the closure location during the time of the closure, and will not be stored onsite.

PR0616171000DEN 2 SECTION 3 Solid PUF Plug with or without Bat Gate

The process for closing a HMO with a solid PUF plug and installation of a bat gate within PUF are presented together in the following steps. The only difference between a solid PUF plug and a PUF plug with a bat gate is the bat gate. The same steps and approach are taken for each closure technique. HMOs that will be closed with PUF shall follow the steps below. 3.1 Preparation Prior to starting any work at the entrance of an HMO: • A work area inspection shall be completed to identify: − Overhanging debris, high walls, etc. − Fall hazards and appropriate tie-off procedures and points − Chemical and explosive hazards − Locations requiring flagging around the work zone to indicate where fall restraints are required and where only authorized staff are allowed − All other applicable hazards • Air monitoring at the HMO shall be completed to ensure the atmosphere is a safe working environment. − Air monitoring standard operating procedures (FMC HMOSP SOP04-14, Appendix E) shall be followed. − Air monitoring includes: radon, oxygen, lower explosive limit, sulfur dioxide, carbon monoxide, and hydrogen sulfide. • If closing an adit or an HMO in which breaking the entrance plane of the HMO is required, the HMO shall be evaluated for confined space determination. • No openings which meet the definition of confined space shall be physically entered by personnel. 3.2 Closure Steps • Perform a work area inspection by physically walking the area and identifying all potential hazards that may exist in the area. • Complete a job hazard analysis (JHA) for each closure activity. • Control, reduce, or eliminate all potential hazards identified in the JHA. If working on an HMO closure with a fall potential, use proper fall protection procedures while working (FMC HMOSP SOP04-02, Appendix E). • Eliminate tripping hazards around the work area and ensure proper housekeeping. • Maintain control of the supplies and equipment being used in the area. Anchor points may need to be established to maintain the weight of the materials being installed until the mine opening has been sealed. Use of rebar stakes, natural terrain features, or equipment may be necessary. Bat gates, vent pipes, drainage pipes, and bulkheads will be secured either by ropes, fir strips, or any other means possible at mine openings.

PR0616171000DEN 3 SECTION 3—SOLID PUF PLUG WITH OR WITHOUT BAT GATE

• Clear all set-up planks and walkways of debris and tripping hazards. All planks/walkways will be secured and anchored in a way to eliminate any twisting or falling motions. Personnel using the scaffolding or planks will be tied off with fall protection devices in accordance with the Fall Protection Guidelines. Handrails are not permitted on planks or walkways. • When closing adit-type features, a rock wall will be built while pouring or spraying the PUF in stages. Insulated concrete form block (ICF) may also be used in lieu of rocks. This allows the foam to be used as grout on the interior of the rock or ICF wall, cementing and anchoring the rocks or ICF into the foam. • When closing shaft-type features, the foam will be poured until reaching a depth below the existing ground surface of approximately 2 feet. Cover material will later be placed on top of the foam to blend into the existing ground surface. • If ICFs are to be used in lieu of local rocks for the exterior face, ICFs shall have the exterior face finish of a polymer-modified cement, reinforced with a woven glass fiber, that will be dyed as close as possible to the surrounding environment. . ICFs shall be reinforced internally with Grade 60 #4 (0.5-inch diameter) rebar . Exterior face finish shall consist of a polymer-modified cement, Omega DryBond® or equivalent. Add one 50 lbs bag of dry mix to 1.5 gallons of water and mix for 3 to 5 minutes. Add concrete dye as needed prior to mixing. See manufactures recommendations for additional details on mixing DryBond. . A thin coat (approximately 1/16” thick) of DryBond shall be applied directly to the clean dry ICF. Place a layer of woven glass fiber reinforcement mesh, AkroFlex® Heavy Duty mesh or equivalent, onto the wet cement and work it into the cement to create a bond between the DryBond and mesh. Immediately cover the mesh with another coat of DryBond that is at least 1/16” thick. Generally, do not exceed a total thickness of 1/4”. See manufactures recommendations for additional details on application of AkroFlex. . Once the DryBond has cured (generally at least 24 hours) apply a siloxane-based penetrating water repellent, OmegaGuard Plus® or equivalent. Apply with a brush, roller or sprayer at a ratio of about 100 ft2 per gallon. See manufactures recommendations for additional details on mixing DryBond. • All adits will have a drain pipe placed within 6 inches of the bottom of the closure to prevent water from building up behind the closure and, wherever possible, sloped so there is positive drainage away from the HMO. In some closures, drain pipes may need to be installed with negative drainage, to prevent water from ponding outside the outer shell of the PUF closure (e.g. decline adit opening in the bottom of a trench, below surrounding area surface grade). To the extent practical, where necessary, and within the approved surface disturbance limits, surfaces shall be graded to promote surface water flows away from the HMO. In addition to minor grading, small scale localized surface water diversions may be constructed to promote surface water flow away from the HMO closure. Constructed diversions may consist of native materials. The footprint of constructed surface water diversions must be within the approved surface disturbance limits. • Some closures will require a bat gate to allow for ingress and egress of bats. − Bat gates shall be placed 4 feet above the floor entrance or as high as possible when 4 feet cannot be achieved. − Bat gates shall have rebar spaced at 6-inch centers. • When two or more openings are obviously connected by underground workings (e.g. an adit opens into a room with a shaft opening in the ceiling), a drainage pipe only needs to be installed in the lowest

PR0616171000DEN 4 SECTION 3—SOLID PUF PLUG WITH OR WITHOUT BAT GATE

opening. In the case of the connected adit and shaft feature, a drainage pipe would only be needed in the adit closure. • When closing an adit with PUF, the depth of the PUF shall be equal to the shortest width or no less than 2 feet. • When closing shaft type features with PUF, the PUF plug depth should generally be designed according to the following equation:

Y = 2a or 3a Where: "Y" equals the PUF plug depth, "a" equals the shorter width and b is the larger width Y =2a when b<3a Y=3a when b>3a

− In some cases, it may not be practical to install PUF to the depth specified in the above equation. One such example of an irregularly-shaped HMO is a cone shaped shaft, where the opening is larger at the surface and tapers down to a smaller hole. Another example is when the depth of the HMO is less than the diameter of the opening. − The bottom of the PUF plug will be set at least 3 feet into bedrock. − If a bat gate is to be used in the closure, cut pipes to length and stage in a proximal area for installation. − If closing an adit-type HMO, ensure all materials which will be used for the outer face are gathered, organized, and placed in proximity to the closure site. − Local rocks may be used to create the outer shell of the PUF plug for adit type PUF closures. ICF may also be used if local rocks are of insufficient quantity. • Prior to mixing the PUF: − Review the safety data sheets (SDS). − Installation of the bulk head backing shall consist of placing 8-ounce non-woven Geo Fabric down the shaft. The fabric shall be suspended and secured by ropes to the appropriate depth. The Geo Fabric shall be placed without stretching and shall be placed in continuous pieces without joints. The fabric shall be placed with overlapping seams perpendicular to the axis of the opening. If more than one fabric strip is necessary, because of the width of the opening being wider than the width of the fabric, the two pieces shall overlap a minimum of 2 feet and pieces shall be laid out to minimize the number of fabric strips required. Approximately 2 feet of excess on each side of the shaft shall be provided to keep the work area clean. The excess fabric will then be trimmed prior to placing earthen materials on top of the PUF. − Establish a mixing area whereby the area needs to be cleared of all debris and a mixing platform needs to be established. Use the bed of the utility task vehicle or other equipment or vehicles, if possible. In areas not accessible by equipment, use cardboard and Geo Fabric to make a mixing platform. • If using barrel sets of PUF, pour two equal parts of the PUF agent into two buckets (5-gallon capacity). The buckets will be marked to have a designated capacity (fill) line. Then take the two buckets containing the two agents and pour the contents into one bucket (5-gallon capacity). Begin mixing with a

PR0616171000DEN 5 SECTION 3—SOLID PUF PLUG WITH OR WITHOUT BAT GATE

1-inch by 2-inch stir stick. The bucket will then be carried to the pour site and poured into the mine opening. • If using the box sets of foam, remove one of the 1/3 cubic yard bags and lay on the mixing area. Remove the divider from the center of the bag. Start mixing the two agents together by placing gloved hands onto the plastic bag and using gentle thorough mixing motions. • Once the agents are mixed thoroughly, pour the PUF into the HMO, starting at the edges if possible. • If utilizing PUF which is sprayed (Dow Froth-Pak), the following personal protective equipment (PPE) shall be worn in addition to other level D PPE (hardhat, steel toed boots, etc.): − Disposable hooded coveralls: Kleengaurd A20, Tyvek, or suitable alternative − Disposable chemical resistant gloves: . Nitrile, Nitrile-Neoprene, or suitable alternative . If leather gloves are desired, then the chemical resistant gloves can be worn beneath leather gloves. − Safety glasses and face shield − Respirator: . With organic vapor cartridges and P-100 particulate filters . A powered air purifying respirator with face shield and appropriate cartridges is acceptable • Spray PUF may only be used in non-vertical load bearing closures (e.g. horizontal HMOs). • The PUF is a two-part compound and is an exothermic reaction; therefore, it generates heat during the curing process. Measuring surface temperatures in between pours can be misleading with respect to starting the next pour or lift. Therefore, a minimum of 10 minutes between each lift will be used when spraying PUF and a minimum of 20 minutes between pours when used barrel sets or 1/3 cubic yard bags. The lift thickness on sprayed PUF shall not exceed more than 4 inches per lift and the lift thickness of poured PUF shall not exceed 18 inches. The PUF should no longer be tacky to the touch. • PUF will be poured in stages until the appropriate elevation is achieved. • Cover the foamed mine opening with approximately 2 feet of soil materials for shafts and establish a complete cover for adits with local rocks or other appropriate material. The final cover for adit type closures will be completed during the last PUF pour or application. The final cover shaft type closures shall be placed no sooner than 4 hours after final PUF pour and no longer that 24 hours after final pour. Foam breaks down from exposure to the ultraviolet rays (i.e. sunlight); therefore, it must be covered to prevent direct exposure. − Information on each type of PUF and their SDS are in Appendix A. The opening should have a natural cover so that it may blend in with the surroundings and environment. Consider all weather and water run-off conditions when closing the HMO. The site will need to be constructed to limit erosion of placed materials. − Soil cover over shafts should be mounded to promote water drainage away from the closure, where reasonably feasible. At some locations, where sufficient soil may not be present to construct a mound to promote drainage, and when the local ground surface topography allows for it, surface water will be diverted away from the depression to limit pooling on the closure. • Paper and electronic documentation of the site and materials will be conducted using site evaluation forms. All the forms will be filled out correctly and entirely. The information is presented in Appendix B. All documentation will be provided to BLM.

PR0616171000DEN 9 SECTION 5 Fencing

Fencing may be installed on adits, shafts, inclines, or declines when it has been determined to be suitable for this closure type. Fencing is not a preferred closure type for HMOs. However, it may be utilized when other permanent closure types cannot be safely completed due to site-specific conditions, which cannot be reasonably mitigated. Adit and shaft fencing minimum standards were borrowed from the Nevada Division of Minerals. The Nevada Division of Minerals fencing specifications minimum standards are compatible with erecting fences in areas where site specific conditions are not conducive to other permanent closure methods due to safety reasons. 5.1 Preparation Prior to starting any work at the entrance of an HMO, a work area inspection shall be completed to identify: • Overhanging debris, high walls, etc. • Fall hazards and appropriate tie-off procedures and points • Chemical and explosive hazards • Locations requiring flagging around the work zone to indicate where fall restraints are required and where only authorized staff are allowed • All other applicable hazards 5.2 Closure Steps • Perform a work area inspection by physically walking the area and identifying all potential hazards that may exist in the area. • Complete a JHA for each closure activity. • Control, reduce, or eliminate all potential hazards identified in the JHA. If working on an HMO closure with a fall potential, use proper fall protection procedures while working (FMC HMOSP SOP04-02, Appendix E). • Eliminate tripping hazards around the work area and ensure proper housekeeping. • Maintain control of the supplies and equipment being used in the area. • Close adit fence: − Fence at a minimum of 6 feet away from adit − 8-foot maximum distance between T-posts without fence stays or 12-foot maximum distance between T-posts with fence stays − Four-strand 12-gauge smooth wire 4 feet high to the top wire − 1 foot between wires with 6-foot heavy duty T-posts − Fence may or may not completely circle adit, dependent on topography − Anchor corners as needed per the drawing in Figure 6 Appendix C − At least one warning sign per adit or 100 feet of fence • Close shaft fence:

PR0616171000DEN 10 SECTION 5—FENCING

All the forms will be filled out correctly and entirely. The information is presented in Appendix B. All documentation will be provided to BLM. Photos will be taken of the mine opening to document existing site conditions and the work being done. Photos will include pictures of the opening, progress views, and pictures of the completed closure. The opening and post-closure photos will include proper identification in effort to document mine opening status at the time of the photo. • Clean up the site when work is finished. Remove all trash and materials that the HMOSP team brought into the area. If trails and walkways were established, re-groom the area to a natural state before leaving the area. 5.3 Material Specifications • Fences will be constructed using galvanized or painted 6-foot heavy duty T-posts, a minimum of 1.25 lb per foot. • The galvanized wire used will be 12-gauge, smooth or barbless.

PR0616171000DEN 11 SECTION 6 Backfilling

This section pertains only to shafts. Adits shall not be closed with a backfill method because compaction of materials cannot be achieved and not all void spaces at the HMO entrance can be sealed adequately. All fill materials used as backfill shall consist of mineral soil, subsoil, or mine waste rock. Backfill materials shall be free from combustible materials such as wood, coal, wood products, trash, and vegetation. Materials shall also consist of clean materials with no visual impacts from mining activities. Only shafts in which the bottom is visible to the operator shall be backfilled. 6.1 Preparation

Prior to starting any work at the entrance of an HMO: • A work area inspection shall be completed to identify: − Overhanging debris, high walls, etc. − Stability of the ground near the shaft that will be used as a work area − Fall hazards and appropriate tie-off procedures and points − Chemical and explosive hazards − Locations requiring flagging around the work zone to indicate where fall restraints are required and where only authorized staff are allowed − All other applicable hazards • Air monitoring at the HMO shall be completed to ensure the atmosphere is a safe working environment. − Air monitoring SOP (FMC HMOSP SOP04-14, Appendix E) shall be followed. − Air monitoring includes: radon, oxygen, lower explosive limit, sulfur dioxide, carbon monoxide and hydrogen sulfide. • If closing an adit or an HMO in which breaking the entrance plane of the HMO is required, the HMO shall be evaluated for confined space determination. • No openings which meet the definition of confined space shall be physically entered by personnel 6.2 Closure Steps • Perform a work area inspection by physically walking the area and identifying all potential hazards that may exist in the area. • Complete a JHA for each closure activity. • Control, reduce, or eliminate all potential hazards identified in the JHA. If working on an HMO closure with a fall potential, use proper fall protection procedures while working (FMC HMOSP SOP04-02, Appendix E). • Eliminate tripping hazards around the work area and ensure proper housekeeping. • Maintain control of the supplies and equipment being used in the area.

PR0616171000DEN 12 SECTION 6—BACKFILLING

Backfilling generally consists of relocating or placing fill materials from outside an HMO to inside an HMO. Local materials located proximal to the opening location are excavated manually and placed down a shaft. • Compacting backfilled material is likely not feasible; therefore, materials placed during backfill shall be mounded to account for future settlement and blended into surrounding contours to the extent practical. • The mound immediately above the shaft shall be extend beyond the perimeter of the shaft. • Surface water runoff shall be diverted around the fill materials to the extent practical. • The site will need to be constructed to limit the erosion of placed materials. • Paper and electronic documentation of the site and materials used will be conducted using site evaluation forms. All the forms will be filled out correctly and entirely. The information is presented in Appendix B. All documentation will be provided to BLM. • Photos will be taken of the mine opening to document existing site conditions and the work being done. Photos will include pictures of the opening, progress views, and pictures of the completed closure. The opening and post-closure photos will include proper identification in effort to document mine opening status at the time of the photo. • The site will be cleaned up when work is finished. All trash and materials that the HMOSP team brought into the area will be removed. If trails and walkways were established, the area will be re-groomed to a natural state before leaving the area. 6.3 Signage All sites will have a warning sign erected at or proximal to the closure location. 6.4 Documentation and Monumentation • Freeport will document all HMO locations with the Universal Transverse Mercator (UTM) coordinate system. • HMO locations will be stored in a geographic information system (GIS) database that will be provided to BLM. • HMO monuments and monument information will consist of the HMO ID (e.g. 4222233HO007) and the year it was closed (e.g. 2017). This information will be stamped into the monument. − Monuments will consist of aluminum markers that are 1.5 to 2.0 inches in diameter. • Monuments will be located proximal to the HMO area that is safe to access.

PR0616171000DEN 13 SECTION 8 Monitoring, Maintenance, and Reporting 7.1 Monitoring and Maintenance HMOs closed by Freeport on BLM administered lands will be monitored as follows: • Year1 1 − Freeport-closed HMOs will be monitored to evaluate the condition of the closure approximately one year after the closure was completed. − If no impairments2 are identified, monitoring will resume at Year 3 after the closure was completed. − If impairments are identified, the closure will be repaired to meet the closure specifications and monitored again at Year 2 after the closure was completed. − The type of impairment will be noted in an HMO closure audit form. • Year 2 − Freeport-closed HMOS with impairments identified in Year 1 will be monitored again in Year 2. − If no impairments are identified, monitoring will resume at Year 3 after the closure was completed. − If impairments are identified, the closure will be repaired to meet the closure specifications. − The type of impairment will be noted in an HMO closure audit form. • Year 3 − If no impairments are identified, monitoring will resume at Year 5 after the closure was completed. − If impairments are identified, the closure will be repaired to meet the closure specifications and monitored again in Year 4. − The type of impairment will be noted in an HMO closure audit form. • Year 4 − If no impairments are identified, monitoring will resume at Year 5 after the closure was completed. − If impairments are identified, the closure will be repaired to meet the closure specifications and monitored again in Year 6. − The type of impairment will be noted in an HMO closure audit form. • Year 5 − When no impairments are identified for three consecutive years, monitoring will conclude and Freeport will consult with BLM to confirm that the HMO closure meets applicable requirements and is complete. − If impairments are identified, the closure will be repaired to meet the closure specifications and monitored again in Year 6.

1 A year for the purposes of monitoring is defined as 9 to 23 months after the date the closure was completed or after the given monitoring period.

2 Impairment is defined as dilapidation of the closure or vandalism detrimental to the integrity of the closure.

PR0616171000DEN 14 SECTION 7—MONITORING, MAINTENANCE, AND REPORTING

− The type of impairment will be noted in an HMO closure audit form. • Beyond Year 5 − Should a closure need to be monitored for an additional period beyond Year 5, the monitoring sequence identified above will be followed until no impairments are identified for three consecutive years. − When no impairments are identified for three consecutive years, monitoring will conclude and Freeport will consult with BLM to ensure that the HMO closure meets applicable requirements and is complete. Should any HMO become a part of a “Plan of Operation” prior to the conclusion of year five or within the three-year time frame following year five, Freeport will not be responsible for the HMO. 7.2 Monitoring and Maintenance Reporting Freeport will document its inspections and auditing of its HMO closures in an HMO closure audit form, which it will provide to BLM in the form of PDF reports and GIS files. The HMO closure audit reports will include a description of the HMO closure (i.e., in good condition, needs repair, reason for repair [i.e., vandalism or dilapidation]), date of audit, name of the auditor, and photograph(s) of the HMO closure. If any repairs are made to an HMO closure, Freeport will provide a description of the repair to BLM. Repairs will be completed consistent with the original closure (i.e., preservation of cultural resources, time frames for threatened and endangered species, etc.). If a repair is inconsistent with or beyond the scope of the original closure, Freeport will consult with BLM prior to completing the repair. At the request of BLM to comply with its regulations located at 43 Code of Federal Regulations (CFR) 3809.401 and 420, Freeport has developed a reclamation plan and a maintenance and monitoring plan for historic mine openings. 43 CFR 3809.401(b)(3) provides: Reclamation Plan. A plan for reclamation to meet the standards in § 3809.420, with a description of the equipment, devices, or practices you propose to use including, where applicable, plans for: (i) Drill-hole plugging; (ii) Regrading and reshaping; (iii) Mine reclamation, including information on the feasibility of pit backfilling that details economic, environmental, and safety factors; (iv) Riparian mitigation; (v) Wildlife habitat rehabilitation; (vi) Topsoil handling; (vii) Revegetation; (viii) Isolation and control of acid-forming, toxic, or deleterious materials; (ix) Removal or stabilization of buildings, structures and support facilities; and (x) Post-closure management.

43 CFR 3809.401(b)(4) states: Monitoring Plan. A proposed plan for monitoring the effect of your operations. You must design monitoring plans to meet the following objectives: To demonstrate compliance with the approved plan of operations and other Federal or State environmental laws and regulations, to provide early

PR0616171000DEN 15 SECTION 7—MONITORING, MAINTENANCE, AND REPORTING detection of potential problems, and to supply information that will assist in directing corrective actions should they become necessary. Where applicable, you must include in monitoring plans details on type and location of monitoring devices, sampling parameters and frequency, analytical methods, reporting procedures, and procedures to respond to adverse monitoring results. Monitoring plans may incorporate existing State or other Federal monitoring requirements to avoid duplication. Examples of monitoring programs which may be necessary include surface- and groundwater quality and quantity, air quality, revegetation, stability, noise levels, and wildlife mortality. This document also serves as the monitoring plan that BLM has requested from Freeport and contains all the information required to satisfy the requirements set forth in 43 CFR 3809.401(b)(3) and (4). Specifically, Freeport’s maintenance and monitoring plan meets the following objectives: • Demonstrates compliance with applicable federal and state environmental laws and regulations • Provides early detection of potential problems with the HMO closures and will supply information that will assist in directing corrective actions with the HMO closures, should they become necessary • Identifies the type and location of monitoring of the HMO closures • Sets forth the frequency of monitoring at HMO closures • Identifies the reporting procedures and procedures to respond to adverse monitoring results at HMO closures

Critical Hazards: Critical Hazards Possible Outcomes Incident Potential Critical Controls Applicable GSR Oxygen deficiency Inhalation or Acute and chronic Ventilation, Confined Space, and/or flammable contact with health effects respiratory Hazardous Gas or toxic gases ignition source including possible protection Policy death, fire, explosion Radon and radon Inhalation with Potential long- Limit exposure NA daughters internal exposure term cumulative time, ventilation, health risk of respiratory cancer and protection possible genetic damage

Definitions: HMOs – Historic Mine Openings represent adits, shafts, trenches, inclines, declines, glory holes or any other distinct identifiable feature, which were used to excavate materials for mining; are no longer in use, and will not be used to excavate mine materials in the near future. Procedure: 1. Initial Air Testing: a. Test the HMO per the FCX Confined Space Policy using a 4-gas meter with oxygen, LEL, carbon monoxide, and hydrogen sulfide sensors (preferred and acceptable readings are listed below).

Gas Preferred Readings Acceptable Readings Oxygen 20.9% 19.5 – 23.5% LEL 0% <10% carbon monoxide 0 ppm <25 ppm hydrogen sulfide 0 ppm <10 ppm

b. The instrument must be set to alarm if readings are not acceptable. c. If readings are not acceptable, leave the HMO immediately. Forced ventilation of the HMO is necessary to continue. d. If readings are acceptable, proceed to Radon Daughter Screening (below).

2. Radon Daughter Screening: a. Test the HMO for radon daughters per the method below (After performing day-of-use instrument detector check, background count and verifying proper pump airflow):

i. Take a sample count in the anticipated work location in or near the HMO by attaching the TM372++ to a tripod with the filter holder positioned at breathing level. ii. Position the tripod/instrument arrangement in the anticipated work location; start the sampling sequence, and retreat from the area. iii. Return after 5 minutes to retrieve the tripod/instrument arrangement and retreat again from the area to remove the filter from the holder and place in the counting tray. iv. Calculate the working level (WL) of radon daughters using the simple equation below (The Calculated Constants Factor will be provided with the counter by the Radiation Safety Officer):

Working Level (WL) = (Sample Count – Background Count) (Calculated Constants Factor)

Ionizing Radiation Preferred Reading Acceptable Reading Radon Daughters <0.02 WL <0.1 WL

If the radon reading is not acceptable, exposures must be limited to the times listed in the table below.

Max. Hours/Week Exposure 1 Radon Daughter Without With ½ Mask With Full-Face With PAPR 2 Conc.

Temporary barriers to block mine outcasting (i.e., plastic sheeting and stick frames and/or forced ventilation of the HMO can be used to increase allowable work times. vi. Continue with preparations to close the HMO with PUF as long as exposure times can be limited to the above table.

3. Closing HMO with PUF: a. Place the 4-gas meter at breathing level in the vicinity of the anticipated work location and proceed with preparations to close the HMO with PUF. b. If the meter alarms at any time during the work, leave the HMO immediately. Forced ventilation of the HMO and acceptable oxygen, LEL, carbon monoxide, hydrogen sulfide and sulfur dioxide readings are necessary to continue.

c. Re-sample radon daughters in the vicinity of the HMO work every hour, if the original average radon daughter concentration was >0.3 WL, and adjust work times based on the results and the times listed in the table above. d. Real-time monitoring for methylene diphenyl diisocyanate (MDI) exposures should be considered at least in representative, worst-case HMO closing projects involving PUF. Such monitoring would involve instrument rental and monitoring by the Industrial Hygienist.

Vapor Preferred Readings Acceptable Readings MDI <5 ppb <20 ppb

e. If MDI readings are not acceptable, stop the work; leave the HMO, and record the readings. Forced ventilation of the HMO and acceptable MDI readings are necessary to continue. f. If readings are acceptable, continue closing the HMO with PUF.

4. FIRST AID MEASURES

Description of first aid measures General advice: First Aid responders should pay attention to self-protection and use the recommended protective clothing (chemical resistant gloves, splash protection). If potential for exposure exists refer to Section 8 for specific personal protective equipment.

Inhalation: Move person to fresh air. If not breathing, give artificial respiration; if by mouth to mouth use rescuer protection (pocket mask, etc). If breathing is difficult, oxygen should be administered by qualified personnel. Call a physician or transport to a medical facility.

Skin contact: Wash off with plenty of water.

Eye contact: Flush eyes thoroughly with water for several minutes. Remove contact lenses after the initial 1-2 minutes and continue flushing for several additional minutes. If effects occur, consult a physician, preferably an ophthalmologist. Suitable emergency eye wash facility should be available in work area.

Ingestion: Do not induce vomiting. Call a physician and/or transport to emergency facility immediately.

Most important symptoms and effects, both acute and delayed: Aside from the information found under Description of first aid measures (above) and Indication of immediate medical attention and special treatment needed (below), any additional important symptoms and effects are described in Section 11: Toxicology Information.

Indication of any immediate medical attention and special treatment needed Notes to physician: Due to structural analogy and clinical data, this material may have a mechanism of intoxication similar to ethylene glycol. On that basis, treatment similar to ethylene glycol intoxication may be of benefit. In cases where several ounces (60 - 100 ml) have been ingested, consider the use of ethanol and hemodialysis in the treatment. Consult standard literature for details of treatment. If

Product name: FROTH-PAK™ 650BF Class A Polyol Spray Issue Date: 10/06/2015 Polyurethane Foam Kit

ethanol is used, a therapeutically effective blood concentration in the range of 100 - 150 mg/dl may be achieved by a rapid loading dose followed by a continuous intravenous infusion. Consult standard literature for details of treatment. 4-Methyl pyrazole (Antizol®) is an effective blocker of alcohol dehydrogenase and should be used in the treatment of ethylene glycol (EG), di- or triethylene glycol (DEG, TEG), ethylene glycol butyl ether (EGBE), or methanol intoxication if available. Fomepizole protocol (Brent, J. et al., New England Journal of Medicine, Feb. 8, 2001, 344:6, p. 424-9): loading dose 15 mg/kg intravenously, follow by bolus dose of 10 mg/kg every 12 hours; after 48 hours, increase bolus dose to 15 mg/kg every 12 hours. Continue fomepizole until serum methanol, EG, DEG, TEG or EGBE are undetectable. The signs and symptoms of poisoning include anion gap metabolic acidosis, CNS depression, renal tubular injury, and possible late stage cranial nerve involvement. Respiratory symptoms, including pulmonary edema, may be delayed. Persons receiving significant exposure should be observed 24-48 hours for signs of respiratory distress. In severe poisoning, respiratory support with mechanical ventilation and positive end expiratory pressure may be required. Maintain adequate ventilation and oxygenation of the patient. Attempt seizure control with diazepam 5-10 mg (adults) intravenous over 2-3 minutes. Repeat every 5-10 minutes as needed. Monitor for hypotension, respiratory depression, and need for intubation. Consider second agent if seizures persist after 30 mg. If seizures persist or recur administer phenobarbital 600-1200 mg (adults) intravenous diluted in 60 ml 0.9% saline given at 25-50 mg/minute. Evaluate for hypoxia, dysrhythmia, electrolyte disturbance, hypoglycemia (treat adults with dextrose 100 mg intravenous). If lavage is performed, suggest endotracheal and/or esophageal control. Danger from lung aspiration must be weighed against toxicity when considering emptying the stomach. Exposure may increase "myocardial irritability". Do not administer sympathomimetic drugs such as epinephrine unless absolutely necessary. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.

5. FIREFIGHTING MEASURES

Suitable extinguishing media: Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers. Foam. Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, but will be less effective.

Unsuitable extinguishing media: Do not use direct water stream. May spread fire.

Special hazards arising from the substance or mixture Hazardous combustion products: During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating. Combustion products may include and are not limited to: Carbon monoxide. Carbon dioxide. Hydrogen halides.

Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation. Blowing agent vaporizes quickly at room temperature. Violent steam generation or eruption may occur upon application of direct water stream to hot liquids.

Advice for firefighters Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound from venting safety device or discoloration of the container. Do not use direct water stream. May spread fire. Move container from fire area if this is possible without hazard. Burning liquids may be moved by flushing with water to protect personnel and minimize property damage. Contain fire water run-off if possible. Fire water run-off, if not contained, may cause environmental damage. Review the "Accidental Release Measures" and the "Ecological Information" sections of this (M)SDS.

Exhaust systems should be designed to move the air away from the source of vapor/aerosol generation and people working at this point. Lethal concentrations may exist in areas with poor ventilation.

Individual protection measures Eye/face protection: Use chemical goggles. Skin protection Hand protection: Use gloves chemically resistant to this material. Examples of preferred glove barrier materials include: Chlorinated polyethylene. Polyethylene. Ethyl vinyl alcohol laminate ("EVAL"). Polyvinyl alcohol ("PVA"). Styrene/butadiene rubber. Viton. Examples of acceptable glove barrier materials include: Butyl rubber. Natural rubber ("latex"). Polyvinyl chloride ("PVC" or "vinyl"). NOTICE: The selection of a specific glove for a particular application and duration of use in a workplace should also take into account all relevant workplace factors such as, but not limited to: Other chemicals which may be handled, physical requirements (cut/puncture protection, dexterity, thermal protection), potential body reactions to glove materials, as well as the instructions/specifications provided by the glove supplier. Other protection: Use protective clothing chemically resistant to this material. Selection of specific items such as face shield, boots, apron, or full body suit will depend on the task. Respiratory protection: Respiratory protection should be worn when there is a potential to exceed the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements or guidelines, use an approved respirator. When respiratory protection is required, use an approved positive-pressure self-contained breathing apparatus or positive- pressure airline with auxiliary self-contained air supply. For emergency conditions, use an approved positive-pressure self-contained breathing apparatus. In confined or poorly ventilated areas, use an approved self-contained breathing apparatus or positive pressure air line with auxiliary self-contained air supply.

4. FIRST AID MEASURES

Skin contact: Remove material from skin immediately by washing with soap and plenty of water. Remove contaminated clothing and shoes while washing. Seek medical attention if irritation persists. Wash clothing before reuse. An MDI skin decontamination study demonstrated that cleaning very soon after exposure is important, and that a polyglycol-based skin cleanser or corn oil may be more effective than soap and water. Discard items which cannot be decontaminated, including leather articles such as shoes, belts and watchbands. Suitable emergency safety shower facility should be available in work area.

Eye contact: Immediately flush eyes with water; remove contact lenses, if present, after the first 5 minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay, preferably from an ophthalmologist. Suitable emergency eye wash facility should be immediately available.

Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by medical personnel.

Indication of any immediate medical attention and special treatment needed Notes to physician: Excessive exposure may aggravate preexisting asthma and other respiratory disorders (e.g. emphysema, bronchitis, reactive airways dysfunction syndrome). Maintain adequate ventilation and oxygenation of the patient. May cause respiratory sensitization or asthma-like

symptoms. Bronchodilators, expectorants and antitussives may be of help. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. Respiratory symptoms, including pulmonary edema, may be delayed. Persons receiving significant exposure should be observed 24-48 hours for signs of respiratory distress. If you are sensitized to diisocyanates, consult your physician regarding working with other respiratory irritants or sensitizers. Exposure may increase "myocardial irritability". Do not administer sympathomimetic drugs such as epinephrine unless absolutely necessary. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.

5. FIREFIGHTING MEASURES

Unsuitable extinguishing media: No data available

Unusual Fire and Explosion Hazards: Product reacts with water. Reaction may produce heat and/or gases. This reaction may be violent. Container may rupture from gas generation in a fire situation. Vaporizes quickly at room temperature. Vapors are heavier than air and may travel a long distance and accumulate in low lying areas. Dense smoke is emitted when burned without sufficient oxygen.

Advice for firefighters Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Stay upwind. Keep out of low areas where gases (fumes) can accumulate. Water is not recommended, but may be applied in large quantities as a fine spray when other extinguishing agents are not available. Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound from venting safety device or discoloration of the container. Do not use direct water stream. May spread fire. Move container from fire area if this is possible without hazard. Use water spray to cool fire- exposed containers and fire-affected zone until fire is out.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment and emergency procedures: Isolate area. Keep unnecessary and unprotected personnel from entering the area. Keep personnel out of low areas.

Page 4 of 15

Product name: FROTH-PAK™ AF 650BF HFC Class A ISO Spray Issue Date: 06/23/2016 Polyurethane Foam Kit

Keep personnel out of confined or poorly ventilated areas. Keep upwind of spill. Spilled material may cause a slipping hazard. Ventilate area of leak or spill. Confined space entry procedures must be followed before entering the area. If available, use foam to smother or suppress. Refer to section 7, Handling, for additional precautionary measures. See Section 10 for more specific information. Use appropriate safety equipment. For additional information, refer to Section 8, Exposure Controls and Personal Protection.

Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. See Section 12, Ecological Information.

Methods and materials for containment and cleaning up: Contain spilled material if possible. Absorb with materials such as: Dirt. Vermiculite. Sand. Clay. Do NOT use absorbent materials such as: Cement powder (Note: may generate heat). Collect in suitable and properly labeled open containers. Do not place in sealed containers. Suitable containers include: Metal drums. Plastic drums. Polylined fiber pacs. Wash the spill site with large quantities of water. Attempt to neutralize by adding suitable decontaminant solution: Formulation 1: sodium carbonate 5 - 10%; liquid detergent 0.2 - 2%; water to make up to 100%, OR Formulation 2: concentrated ammonia solution 3 - 8%; liquid detergent 0.2 - 2%; water to make up to 100%. If ammonia is used, use good ventilation to prevent vapor exposure. Contact your supplier for clean-up assistance. See Section 13, Disposal Considerations, for additional information.

7. HANDLING AND STORAGE

OSHA Z-1 C 0.2 mg/m3 0.02 ppm 1,1,1,2-Tetrafluoroethane US WEEL TWA 1,000 ppm

Exposure controls Engineering controls: Use only with adequate ventilation. Local exhaust ventilation may be necessary for some operations. Provide general and/or local exhaust ventilation to control airborne levels below the exposure guidelines. Exhaust systems should be designed to move the air away from the source of vapor/aerosol generation and people working at this point. The odor and irritancy of this material are inadequate to warn of excessive exposure. Lethal concentrations may exist in areas with poor ventilation.

Individual protection measures Eye/face protection: Use chemical goggles. Skin protection Hand protection: Use gloves chemically resistant to this material. Examples of preferred glove barrier materials include: Butyl rubber. Polyethylene. Chlorinated polyethylene. Ethyl vinyl alcohol laminate ("EVAL"). Examples of acceptable glove barrier materials include: Viton. Neoprene. Polyvinyl chloride ("PVC" or "vinyl"). Nitrile/butadiene rubber ("nitrile" or "NBR"). NOTICE: The selection of a specific glove for a particular application and duration of use in a workplace should also take into account all relevant workplace factors such as, but not limited to: Other chemicals which may be handled, physical requirements (cut/puncture protection, dexterity, thermal protection), potential body reactions to glove materials, as well as the instructions/specifications provided by the glove supplier. Other protection: Use protective clothing chemically resistant to this material. Selection of specific items such as face shield, boots, apron, or full body suit will depend on the task. Respiratory protection: Atmospheric levels should be maintained below the exposure guideline. When atmospheric levels may exceed the exposure guideline, use an approved air- purifying respirator equipped with an organic vapor sorbent and a particle filter. For situations where the atmospheric levels may exceed the level for which an air-purifying respirator is effective, use a positive-pressure air-supplying respirator (air line or self-contained breathing apparatus). For emergency response or for situations where the atmospheric level is unknown, use an approved positive-pressure self-contained breathing apparatus or positive- pressure air line with auxiliary self-contained air supply. In confined or poorly ventilated areas, use an approved self-contained breathing apparatus or positive pressure air line with auxiliary self-contained air supply. The following should be effective types of air-purifying respirators: Organic vapor cartridge with a particulate pre-filter.

NOTE: The physical data presented above are typical values and should not be construed as a specification.

10. STABILITY AND REACTIVITY

Reactivity: No data available

Chemical stability: Stable under recommended storage conditions. See Storage, Section 7.

Possibility of hazardous reactions: Can occur.

Conditions to avoid: Elevated temperatures can cause container to vent and/or rupture. Exposure to elevated temperatures can cause product to decompose. Generation of gas during decomposition can cause pressure in closed systems. Pressure build-up can be rapid. Avoid moisture. Material reacts slowly with water, releasing carbon dioxide which can cause pressure buildup and rupture of closed containers. Elevated temperatures accelerate this reaction.

Incompatible materials: Avoid contact with: Acids. Alcohols. Amines. Ammonia. Bases. Metal compounds. Strong oxidizers. Diisocyanates react with many materials and the rate of reaction increases with temperature as well as increased contact; these reactions can become violent. Contact is increased by stirring or if the other material mixes with the diisocyanate. Diisocyanates are not soluble in water and sink to the bottom, but react slowly at the interface. The reaction forms carbon dioxide gas and a layer of solid polyurea. Reaction with water will generate carbon dioxide and heat. Avoid unintended contact with polyols. The reaction of polyols and isocyanates generate heat.

Page 7 of 15

Product name: FROTH-PAK™ AF 650BF HFC Class A ISO Spray Issue Date: 06/23/2016 Polyurethane Foam Kit

Hazardous decomposition products: Decomposition products depend upon temperature, air supply and the presence of other materials. Toxic gases are released during decomposition.

11. TOXICOLOGICAL INFORMATION

Toxicological information appears in this section when such data is available.

Acute toxicity Acute oral toxicity Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury. Observations in animals include: Gastrointestinal irritation.

As product: Single dose oral LD50 has not been determined. LD50, Rat, > 2,000 mg/kg Estimated.

Acute dermal toxicity Prolonged skin contact is unlikely to result in absorption of harmful amounts.

As product: The dermal LD50 has not been determined. LD50, Rabbit, > 2,000 mg/kg Estimated.

Acute inhalation toxicity In confined or poorly ventilated areas, vapor can easily accumulate and can cause unconsciousness and death due to displacement of oxygen. Excessive exposure may cause irritation to upper respiratory tract (nose and throat) and lungs. May cause pulmonary edema (fluid in the lungs.) Effects may be delayed. Decreased lung function has been associated with overexposure to isocyanates. Excessive exposure may increase sensitivity to epinephrine and increase myocardial irritability (irregular heartbeats). May cause central nervous system effects. Symptoms of excessive exposure may be anesthetic or narcotic effects; dizziness and drowsiness may be observed. As product: The LC50 has not been determined.

Skin corrosion/irritation Prolonged contact may cause skin irritation with local redness. May stain skin.

Serious eye damage/eye irritation May cause moderate eye irritation. May cause slight temporary corneal injury.

Sensitization Skin contact may cause an allergic skin reaction. Animal studies have shown that skin contact with isocyanates may play a role in respiratory sensitization.

May cause allergic respiratory reaction. MDI concentrations below the exposure guidelines may cause allergic respiratory reactions in individuals already sensitized.

Page 8 of 15

Product name: FROTH-PAK™ AF 650BF HFC Class A ISO Spray Issue Date: 06/23/2016 Polyurethane Foam Kit

Asthma-like symptoms may include coughing, difficult breathing and a feeling of tightness in the chest. Occasionally, breathing difficulties may be life threatening.

Specific Target Organ Systemic Toxicity (Single Exposure) May cause respiratory irritation. Route of Exposure: Inhalation

Specific Target Organ Systemic Toxicity (Repeated Exposure) Tissue injury in the upper respiratory tract and lungs has been observed in laboratory animals after repeated excessive exposures to MDI/polymeric MDI aerosols.

Carcinogenicity Lung tumors have been observed in laboratory animals exposed to respirable aerosol droplets of MDI/Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with respiratory irritation and lung injury. Current exposure guidelines are expected to protect against these effects reported for MDI.

Teratogenicity In laboratory animals, MDI/polymeric MDI did not cause birth defects; other fetal effects occurred only at high doses which were toxic to the mother. Contains component(s) which did not cause birth defects in animals; other fetal effects occurred only at doses toxic to the mother.

Reproductive toxicity No relevant data found.

Mutagenicity Genetic toxicity data on MDI are inconclusive. MDI was weakly positive in some in vitro studies; other in vitro studies were negative. Animal mutagenicity studies were predominantly negative.

Aspiration Hazard Based on physical properties, not likely to be an aspiration hazard.

A Better Way to Build

RASTRA is the ultimate building solution for economical and environmentally‐friendly construction. RASTRA is the solution for this century to build environmentally conscious, energy efficient buildings that provide a safe and healthy living environment. Over 9 million units in service worldwide.

Applications The strength and flexibility of RASTRA make it the ideal building solution for single family walls & basements, multi‐ family, enclosed patio rooms and commercial buildings. As a general rule, any common finish can be applied to RASTRA panels to achieve any desired appearance. Interior – Drywall, plaster, stucco, tile, stone and paneling can be applied directly to RASTRA. Environmentally Friendly Exterior ‐ RASTRA is suitable for a wide range of exterior finishes including any type of siding, stone, brick or stucco. RASTRA is 85% recycled polystyrene, which otherwise would have ended up in landfills never to disintegrate. Energy Efficient RASTRA buildings reduce energy consumption, and In the past buildings were built with little emphasis placed with energy savings comes environmental benefits. on energy conservation, largely because we enjoyed low oil Specifically, the reduction of fossil fuels burned to prices. These are different times, and with unprecedented create energy. By reducing our energy consumption, increases in energy costs, improving insulating efficiency is we reduce combustion by‐products that lead to smog a financial decision that pays dividends for the life of the and contribute to global warming. Over the life of a property. 30‐year mortgage, a home built with RASTRA saves An industry study concluded that ICF walls typically require our atmosphere 60‐90 tons of carbon dioxide (CO2) 44% less energy to heat the building and 32% less to keep it emissions. Another measure of sustainability is cool compared to wood frame buildings. increased service life. Products that last longer make a large impact on our solid landfills. RASTRA’s superior thermal performance and air tightness greatly reduces heat loss and lowers energy consumption. RASTRA is an ecological sound building By increasing the Effective U‐value with RASTRA, HVAC material, consuming recycled raw materials, equipment operates less often, reducing energy costs. taking them permanently out of the waste Because less moisture filled air penetrates exterior walls, air stream and producing a healthy living conditioners don’t work as hard to remove humidity from environment for occupants. the air. Heat loss from hot water pipes is also reduced. Safety Fire Protection One of the most important features of any building is RASTRA’s superior 4‐hour+ fire rating helps protect from its ability to protect human life. RASTRA’s steel the devastating loss caused by fire. When an independent reinforced concrete walls provide a safe and secure testing lab exposed a full scale environment. Safety features include: RASTRA wall to constant 2000° F :: Highly fire resistant – 4 hour fire rating (1200°C) flames for 5 hours, the @2000°F; material will not ignite; produces opposite side of the panel the no toxins, zero flame spread; smoke density temperature rose only 7° F (4°C) of 5 (450 is permissible). with no flame spread or smoke. :: Effective barrier from wind‐driven debris. Strength :: Earthquake tested up to magnitude level 8 Superior strength is expected from a wall system made of with no structural damage. steel reinforced concrete over one made of wood. The impressive feature is just how much stronger. Dynamic :: Cleaner indoor air quality. shear tests designed to simulate earthquakes have measured strength up to 700% stronger than wood frame walls.

Cost‐of‐Ownership Maintenance RASTRA costs slightly more than traditional building Traditional wood frame construction is prone to decay materials. However RASTRA provides savings in several and insects caused by moisture which deteriorates other areas including downsizing to a less expensive HVAC wood. As lumber ages it shrinks and warps. Over time unit, potential tax credits, eliminating membrane and wire walls loosen and eventually weaken. Gaps begin to mesh on stucco installations, and eliminating the need for appear allowing destructive moisture to gain access. an additional vapor barrier. With RASTRA, wood rot is a thing of the past. Most stucco cracks are actually caused by substrate walls RASTRA is the least expensive option by far over the life of moving from lumber changing dimension – this the property. Heating and cooling costs are reduced by at problem is virtually eliminated with RASTRA. RASTRA least 40% each and every year. Maintenance costs are is dimensionally stable and protects your property by reduced because timber that warps and degenerates is maintaining a more watertight layer of protection that replaced by dimensionally stable RASTRA. HVAC units greatly reduces maintenance. have a longer service life because it doesn’t work as hard or often to maintain environmental settings. RASTRA Quiet provides the lowest cost‐of‐ownership available. RASTRA provides outstanding acoustical performance. Indoor Air Quality The increased mass and density of RASTRA provides a very effective sound barrier, keeping outside noise The unique composition of RASTRA enables better control from penetrating the exterior wall. over indoor air quality. Because RASTRA does not hold or wick water like concrete block or wood, RASTRA will not Compared to a typical wood frame wall, 75% to 85% promote or sustain mold and mildew. less sound passes through a RASTRA wall. Scientists describe loud speech on the opposite side of a RASTRA The composition of RASTRA allows a slow interchange of wall as, “a listener would strain to hear loud speech. It is air, which in turn allows the building to "breathe." The virtually inaudible." exchange is slow enough that it does not allow heat or cold to escape but helps maintain good air quality, preventing In an independent survey, owners of 74 new ICF homes "sick building syndrome." This slow exchange of air also and 73 new wood frame homes were asked what prevents condensation that can lead to mold growth. features they liked. Over 60% of ICF homeowners mentioned the quietness of their homes, versus only Comfort 2% of the wood frame homeowners. Being in a RASTRA building is a comfortable experience. Interior walls built with RASTRA reduce the movement This results from more consistency in room‐to‐room of airborne sound from one room to another. Privacy temperature & humidity, improved air quality, and a much is enhanced. quieter space. Code Compliance In an independent survey, owners of 74 new ICF homes and 73 new wood frame homes were asked what features they RASTRA satisfies international codes (for example ICC, liked. Over 80% of the ICF owners mentioned the great EOTA) and production is audited by recognized comfort, compared with 22% of wood frame homeowners. organizations to meet requirements for commercial and residential applications. Insects

Unlike solid polystyrene, the mixture of cement and polystyrene in RASTRA creates an undesirable inert environment for insects. Concrete fills the interior channels and pores of the surface, thereby eliminating channels that termites and other insects could use for migration and nesting.

Appendix E Standard Operating Procedures

Gas Preferred Readings Acceptable Readings Oxygen 20.9% 19.5 – 23.5% LEL 0% <10% carbon monoxide 0 ppm <25 ppm hydrogen sulfide 0 ppm <10 ppm

2. Radon Daughter Screening: a. Test the HMO for radon daughters per the method below (After performing day-of-use instrument detector check, background count and verifying proper pump airflow):

Working Level (WL) = (Sample Count – Background Count) (Calculated Constants Factor)

Ionizing Radiation Preferred Reading Acceptable Reading Radon Daughters <0.02 WL <0.1 WL

If the radon reading is not acceptable, exposures must be limited to the times listed in the table below.

1 Table assumes a maximum work week of 40-hours and is applicable to the FCUP 2016 field season with its dose constraint of 100 mrem/year 2 Equipped with type R100 particulate filters 3 APF = Assigned Protection Factor 4 At MSHA sites, respirators approved for radon daughters are required in all areas >1.0 WL. 5 At MSHA sites where the radon daughter concentration is >10 WL, respiratory protection against radon gas must be provided in addition to protection against radon daughters (e.g. supplied-air respirators). v. Temporary barriers to block mine outcasting (i.e., plastic sheeting and stick frames and/or forced ventilation of the HMO can be used to increase allowable work times. vi. Continue with preparations to close the HMO with PUF as long as exposure times can be limited to the above table.
