Public Input No. 309-NFPA 10-2014 [ Global Input ]

Proposal for Change to NFPA 10 Background behind Proposal Assumptions that all metals listed within the Class D category burn in similar ways is a long standing issue when it comes to selecting the correct fire extinguishing agent to use. The metals typically listed in this fire Class are below along with their classifications according to the Periodic Table of Elements; Alkali Earth Metals – Magnesium (solid fire) Alkali Metals – Lithium, Sodium, Potassium (molten fires) Transition Metals – Titanium, Zirconium (solid fire) Poor Metals – Aluminium (solid fire) Individually all of these burn with slightly different characteristics and have different specific gravities, varying flash points, ignition temperatures, boiling points and melting points, therefore it makes sense that each should be treated individually when it comes to optimum choice of fire extinguishing agent. UL711 – Rating and testing of Fire Extinguishers requires that any Class D agent should be able to effectively and efficiently extinguish Magnesium (a solid when burning) and Sodium (molten when burning). The test itself is only on very small quantity of each metal and therefore it is wrong to assume that a Class D extinguishing agent is optimised for both a solid and molten metal fire if they pass this small scale test, when they realistically are suited only to one or the other. Specialist extinguishing agents for this difficult category need to be tested on a more specific metal basis and in a more stringent test to ensure optimised extinguishing agents are used in the relevant areas and relevant Standards need to be changed to allow this. Our Proposed Change to NFPA 10 Dupre Minerals would like to see changes in the way that the Class D section is viewed, and rather than have a generic Class, that it should be broken down into the minimum following 2 categories; Solid Burning metals , such as Magnesium, Titanium, Aluminium and Zirconium Molten burning metals , such as Sodium, Potassium, Lithium and Zinc NFPA 10 Sections 5.3.2.4 and NFPA 10 Annex A.6.5.1 both refer to Class D fire extinguisher selection being specific to the type of metal present, and therefore we believe that NFPA 10 should change the statements in these 2 sections to be more specific to state that, “fire extinguisher selection needs to be relevant to where there is solid burning or molten burning metals are present”. The term ‘Class D’ should also be reviewed, this is because you have 2 physically different fire types within it, and within each of the solid and molten metal categories, the metals listed themselves have different burning characteristics. As an initial step, we believe that Class D should either state Class D Solid and Class D Molten or something similarly relevant that can also lead to better labelling on the relevant extinguisher types. Other areas within NFPA 10 where more specific statements regarding Solid burning and molten burning metal fires could be made to reflect the above proposals are as follows; Section 5.5.8.1 to state – “Class D fire extinguishing agents shall be compatible wit the specific solid or molten metal type for which protection is required” Section 6.5.1 – to state “Fire extinguishing agents with Class D solid metal or Class D molten metal approvals shall be provided for fires involving the relevant combustible metal types. Annex C, C.2.11 – to state, “Only extinguishing Agents specifically tested and approved for either Solid burning metals or liquid burning metals and approved for use on particular combustible metal fire types should be selected and provided.”

Annex E, E.6.1 – to state, “…the availability of approved solid or molten burning metal portable extinguishers is particularly important….” Annex E, E.6.2 – to state, “ Use of the incorrect fire extinguisher type (solid metal or molten metal) can either affect the ability to extinguish the fire or worse, can instantly increase or spread the fire…..” Annex G, G.1.1 part (4) - to state “Class D rating to specify whether the agent is suited to (a) solid burning metals, (b) molten burning metals or (c) solid and molten metals and the classification is subject to special tests on specific combustible metal fires” As a future consideration, Annex G could also include classifications that are based upon;

Solid or molten metal specific fires Metal specific fires (ie Magnesium OR sodium)

We believe that NFPA 10 is a very influential document and if this Standard is changed to reflect the proposals made, then other industry standards will follow, for example UL711. Changes to UL711 could then lead to specific tests for specific flammable metal types, yielding more relevant approvals for metal specific extinguishing agents.

Statement of Problem and Substantiation for Public Input

Clear classification of the Class D flammable metal types, specifically acknowledging that some metals burn as solids and some burn as liquids. This is important when testing the fire extinguishing agent and allows the optimum agent to be considered.

Committee Statement

Resolution: The submitter appears to be asking for new listing criteria to be established by NFPA 10. The standard already requires listing of Class D extinguishers to be appropriate for the specific material. The committee has formed a task group to study this topic for possible action at the Second Draft stage.

(as amended by the final rule published on September 15, 2010)

Statement of Problem and Substantiation for Public Input

NFPA 10 should recognize ADA requirements and accommodate them where achievable. Examples include the current NFPA-10 limit for the installation height of portable fire extinguishers. NFPA-10 lists 60 inches as the limit, while ADA presently states that accessible objects should be no higher than 48 inches. It should also be mentioned within NFPA-10 that any object whose bottom edge is higher than 27 inches should not protrude more than 4 inches into the adjacent path of travel, per ADA requirements. On the state and local level, most building codes reference directly, or indirectly, ANSI A117.1. ANSI A117.1 states the same limits for height and protrusion limits as ADA.

Canada has ratified the United Nations Convention on the Rights of Peoples with Disabilities (CRPD), and before the next edition of NFPA-10 is issued, the US Senate may have ratified it as well. Countries which ratify the CRPD are supposed to harmonize their accessibility standards with ISO 21542. ISO 21542 requirements are slightly different that the US ADA rules. For example, accessible objects are to be installed no higher than 43 inches, and any object with a bottom leading edge of 11.8 inches cannot protrude more than 4 inches.

A mention within the next NFPA-10 such as "National, State, and Local accessibility codes and standards shall be recognized as having final authority for installation heights and protrusion limits" would be a good "catch all" statement which will allow this section of NFPA-10 to remain current while height limits continue evolve over time.

New annex material for 3.3.27 A.3.3.27 For Class A hazards, travel distance is from any point to an extinguisher. For Class B, D, and K hazards, travel distance is measured from the hazard to an extinguisher (or agent container for Class D). Travel distance will be affected by partitions, location of doorways, aisles, piles of stored materials, machinery, and other walking obstructions. It is important to consider these obstructions as a person retrieving an extinguisher will need to walk around obstructions, which takes time.

Add a new requirement to the extinguisher label.

Add to the label or have it stamped into the bottom of the extinguisher shell the date of manufacture.

It is sometimes hard to find on an extinguisher when the extinguisher was made. This date is needed to determine the 6 and 12 year maint. requirements. Requireing it to be placed in the same place for all extinguishers will standize this information and easier to preform the maint.

There are currently numerous types of vaporizing liquid clean extinguishing agents in use today that are acceptable, i.e. Halon 1211 and Halotron 1. Though these agents may be categorized as Halogenated Agents, they still also fall under the broader general category of "vaporizing liquids". If left as written, #3 automatically obsoletes all of those acceptable vaporizing liquid extinguishing agents - both currently in use and those to come in the future. My recommendation is remove the "vaporizing liquid" description and to specifically list those agents that need to be obsoleted.

Statement of Problem and Substantiation for Public Input

In the 2007 edition of NFPA-10 (6 years ago), this section was exactly the same. However, it states that these extinguishers shall be removed from service at the next 6-year maintenance interval or hydro test. If a fire extinguisher received 6-year maintenance in 2006, just before the 2007 edition of NFPA-10, than that extinguisher is up for “the next 6-year maintenance” in 2012. So I was expecting the 2013 edition of NFPA-10 to re-word this section as to require the removal of service to be immediately. A similar matter was addressed in section 5.5.5.4 of the 2007 edition of NFPA-10 regarding fire extinguishers without Class K rating that were installed for the protection of Class K hazard. In 2013 this section (5.5.5.4) was eliminated and 5.5.5 prevailed because the 6-year maintenance interval had already passed since 2007. The same should apply to section 4.4.1. Furthermore, including the month (October) can be a matter of much debate between someone that is unaware of the year changing month in manufacturing fire extinguishers. Besides, if a fire extinguisher was manufactured prior of October 1984 the indicated manufacturing date on the cylinder will be “1984”, but if it was manufactured in October 1984 or after, the manufacturing date on the cylinder will be “1985”. So if section 4.4.1 was to be re-worded as to eliminate the month and just specify the manufacturing year, much confusion would be avoided. In the 2007 edition of NFPA-10 (6 years ago), this section was exactly the same. However, it states that these extinguishers shall be removed from service at the next 6-year maintenance interval or hydro test.

5.3.2.4*.1 Fire extinguishers and extinguishing agents for the protection of Class D hazards shall be of the types specifically listed and labeled for use on the specific combustible metal hazard. 5.3.2.4 .2 The criteria for determining the threshold where Class D fire extinguishers are required shall be determined on the basis of a risk assessment approved by the Authority Having Jurisdiction. Annex Item A.5.3.2.4.2 Among the criteria for this determination shall be the quantity of Class D material, its method of handling and whether the premises is sprinklered.

Statement of Problem and Substantiation for Public Input

In some laboratory environments combustible metals are used in very small quantities. Class D fire extinguishers are relatively costly to buy and maintain . Where the quantity is very small -- and the premises where the material is being used is protected with sprinklers or other apparatus that isolates a fire risk -- a Class D fire extinguisher in an isolated location may not reduce overall risk as much as having portable extinguishers for other fire hazards in other locations in the facility that may not be sprinklered.

Scale, balance and cost rationalization are essential components of an effective fire safety program in light of the fact that it is financially impossible to conform to codes and standards that govern all safety risks. Securing a risk assessment that takes a broader view of the facility protection regime may inform the allocation of fire protection technology that has the practical effect of netting greater fire protection and safety.

Section 5.5.4 number (3 ")Larger capacity extinguishers of 10 lb (4.54 kg) or greater and a minimum discharge rate of 1 lb/sec (0.45 kg/sec)" was changed ithis edition and the last edition to require an increase in flow rate from previous editions of NFPA 10. Although I do not disagree with the increase in flow rate I do think that there should be time allowed to meet this increase. Extinguishers should be replaced when they fail hydro or after 12 years or an approved agree upon plan with the AHJ. An example is the Sentry 10 A10H has a discharge rate of 0.52 lb/sec and the Sentry 10 AA10S has a discharge rate of 0.52 lb / sec. By allowing for time to replace these extinguishers we are avoiding unnecessary cost and materl excessed for recycling.

Public Input No. 334-NFPA 10-2015 [ Section No. 5.5.7.1 ]

5.5.7.1 Only water-type extinguishers shall be installed in areas containing oxidizers, such as pool chemicals Fire extinguishers intended for use on oxidizer fires, shall be selected and installed based upon the specific recommendations contained within the materials SDS or MSDS .

Statement of Problem and Substantiation for Public Input

There are oxidizers that specifically advise against the application of water. Because the specific type of oxidizer, state of the material and the quantiy present can affect various extinguishment recommendations, referencing the materials SDS is advisable. This proposal also helps clarify the intent assoicated with the selection and placement of fire extinguishers specifically intended for use addressing oxidizer fire situations.

The proposed change brings NFPA 10 in line with the 2013 edition of NFPA 400 - Hazardous Materials Code. There are oxidizers that are incompatible with the application of water. Because the specific type of oxidizer, state of the material, and the quantity present can affect various extinguishment recommendations, referencing the materials SDS is advisable.

Public Input No. 329-NFPA 10-2015 [ Sections 5.5.7.1, 5.5.7.2 ]

Sections 5.5.7.1, 5.5.7.2, 5.5.7.3 5.5.7.1 Only water-type extinguishers shall be installed in areas containing oxidizers, such as pool chemicals Dry Extinguisher Chemical and CO2 s. The placement and use of carbon dioxide (CO 2 ) or dry extinguisher chemical s containing ammonium compounds (Class A:B:C) shall be prohibited in areas where oxidizers that can release chlorine or bromine are stored .

5.5.7.2 * Multipurpose dry chemical fire Extinguisher extinguisher Halon s. Halon s shall not be used in areas where oxidizers are stored.

5.5.7.3 Halocarbon Clean Agent Extinguishers. Halocarbon cean agent extinguishers shall not be installed used in areas containing where oxidizers , such as pool chemicals. are stored, unless they have been tested to the satisfaction of the AHJ.

Statement of Problem and Substantiation for Public Input

The proposed change is necessary for several reasons. First, the proposed change brings NFPA 10 in line with the 2013 edition of NFPA 400 - Hazardous Materials Code. Second the proposed change provides additional valuable guidance concerning the use of halon and halocarbon extinguishers on fires involving oxidizers. Third, the proposed language restores the original intent of the section, which was to prohibit just the use of dry chemicals containing ammonium compounds, and not ALL dry chemicals. Fourth, the proposed language restores the original intent of the section, which was to prohibit the use of ammonium based agents in areas where oxidizers can release chlorine and not prohibit the use of ALL dry chemicals on ALL types of oxidizers, as it stands currently. Fifth, the proposed language would restore congruity with the verbiage found in the 2013 edition of NFPA 10 in Annex H.2 (6) which states that "A dry chemical fire extinguisher containing ammonium compounds should not be used on oxidizers that contain chlorine. The reaction between the oxidizer and the ammonium salts can produce the explosive compound nitrogen trichloride (NCl3)." Finally, water-type fire extinguishers are not acceptable to use on all types of oxidizers, as our current language suggests. For example, sodium peroxide is an oxidizer that reacts "violently with water" and the MSD specifically requires the use of dry chemical. Therefore, specifying that only water types should be used could create a serious safety problem with certain oxidizers. Additionally, oxidizers can take the form of solid, liquid, or gas and water may not be effective on oxidizers in certain forms. Those who specify extinguishing agents should be able to reference the MSDS and recommend the agent that is safe to use and most effective for the particular type of oxidizer in the specific state (solid, liquid, or gas) in which it is found.

Statement of Problem and Substantiation for Public Input

I do not think fire extinguishers should be placed in stairways, exit passageways, and other areas where persons are considered "safe" from the fire area. Once in an exit (as defined by NFPA 101), persons should follow the egress flow and evacuate the building. The idea of safely reaching an exit, and then suggesting that a person should re-enter the hazardous area with a fire extinguisher is against all concepts established by NFPA 101, good judgment, and prudency.

Statement of Problem and Substantiation for Public Input

UL and ULC formed a Portable Fire Extinguisher Technical Harmonization Committee to issue a single standard for fire extinguishers. The Portable Extinguisher Technical Harmonization Committee (THC 605) made a change to testing standards ANSI/UL 711 and CAN/ULC S508 in 2002. The change was in the net mass of the wood crib used to establish a 1-A through 10-A rating (i.e., greater than a 40% increase in net mass for a 10-A rating than before). The increase in mass was adopted to align ANSI/UL 711 with CAN/ULC-S508 criteria.

All fire extinguisher manufacturers were required to resubmit their fire extinguishers to UL by February 2011 for retesting. UL 711, Rating and Fire Testing of Fire Extinguishers, which now is a harmonization of Underwriters Laboratories of Canada CAN/ULC-S508 Fourth Edition and Underwriters Laboratories Inc. ANSI/UL 711 Seventh Edition, has resulted in an A rating for fire extinguishers that is less than previous numeric ratings for the same amount of dry-chemical agent. The results from the new testing criteria, larger wood-crib construction per A classification rating, concludes a fire extinguisher with 10 pounds of dry-chemical agent is now rated as 4-A versus 10-A.

Due to these changes by UL, fire extinguishers with a rating of 10-A:60-B:C is no longer available from the site’s present supplier. The replacement to the former 10-A:60-B:C rated fire extinguishers are 4-A:80-B:C rated. NFPA 10 establishes coverage areas and placement of extinguishers based on these ratings. The issue concerns the A rating of the new fire extinguishers. Per NFPA 10, Table 6.2.1.1 and Annex E, “ordinary hazard occupancy” for Class A hazards has a maximum coverage area of 1500 square feet per unit of A rating. In contrast, “light hazard” is 3000 square feet per unit of A rating and “extra hazard” is 1000 square feet per unit of A rating, In all cases, the maximum floor area for a fire extinguisher is 11,250 square feet. By comparison, the new fire extinguisher rating (4-A) will typically cover 6000 square feet (ordinary hazard), whereas the old fire extinguisher rating (10-A) covered up to the maximum 11,250 square feet. The requirement for maximum travel distance to a fire extinguisher is still 75 feet. With the harmonization of the test standard, replacement extinguishers, rated type 4-A:80-B:C rated, potentially may not comply with the NFPA 10 coverage area requirements if mounted in the same position because the decreased rating has reduced the maximum coverage area by 43%.

Recent editions of NFPA 10 have not made changes to the spacing requirements since the testing requirements by UL/ULC were revised in 2002 .

NFPA 10 fails to emphasize the need for regular maintenance of fire hoses that are installed in lieu of fire extinguishers.

NFPA 10 requires fire extinguishers to be regularly maintained. As long as fire hoses are recognized in NFPA 10 (6.2.1.4) as an acceptable alternative for up to 1/2 of the required complement of class A rated fire extinguishers, it is important that NFPA 10 also require that those fire hoses be properly maintained.

TITLE OF NEW CONTENT Type your content here ... 7.2.1.5 Fire extinguishers mounted in vehicles shall be visually inspected daily, or, if the vehicle is not used daily, the fire extinguishers shall be inspected each time the vehicle is used.

Statement of Problem and Substantiation for Public Input

Several NFPA standards require portable fire extinguishers in vehicles. These documents refer to NFPA 10 for installation and maintenance criteria. Fire extinguishers in vehicles present different challenges than those in buildings. For instance, mounting extinguishers in vehicles requires a bracket that will hold the extinguisher in place when the vehicle is in motion, or when the vehicle is in an accident. In many cases, the extinguisher is placed in the cargo compartment of the vehicle, where it is subject to impact from other items in the compartment, and temperature extremes not seen in buildings. Because of these potentialities, it becomes necessary for these extinguishers to be checked more frequently than those installed in stationary locations like buildings.

Submitter Information Verification

Committee Statement

Resolution: This topic is already addressed in A.7.2.2.1. The standard requires a minimum of monthly inspections in 7.2.1.2.1, but more frequent inspections are permitted and encouraged where appropriate.

Fire extinguishers and Class D extinguishing agents shall be inspected either manually or by means of an electronic monitoring device/system at intervals not exceeding 31 once each month, not exceeding 45 days.

Statement of Problem and Substantiation for Public Input

The 31 day maximum interval for the "monthly" inspection is too restrictive. For example, if the inspection were performed on the first working day of each month, with holidays and weekends: The first weekday of each month till the next month is very often more than the 31 day maximum. During 2014 from Jan. 2 till Feb. 3 is 32 days. From May 1st till June 2nd is again 32 days. From August 1st till Sept. 2nd is 32 days. From October 1st till November 3rd is 33 days. Additionally I feel this very restrictive for me as an outside contractor to have to schedule to be at a customer's facility on the 31 day maximum schedule. It should be lengthened to 45 days. I would normally schedule these inspections at each facility a specific week of the month. For example the technician would be given the work order to perform the inspection during the 1st week of the month. But if a month starts on Thursday or Friday and there is other emergency work and it then gets done early the next week then this would be up to 35 to 40 days. The 45 day timeframe would give a little flexibility.

Statement of Problem and Substantiation for Public Input

There is no way for an AHJ to adequately know if a listed quick seal has indeed been changed or not. Placing a year on the quick seal to match that of the year on the maintenance tag will ensure that the quick seal has been changed. Numerous AHJ’s have complained about the consistent issue of fire equipment dealers not changing the quick seals when performing annual maintenance. The issue became so widespread in one state that multiple dealers were found tagging one manufacturers extinguishers seven years after manufacture without having changing the original quick seal from the manufacturer. This was easy to spot as the manufacturer has a seal that has a logo on it.

7.7.2.3.1 The premixed agent in liquid charge–type AFFF and FFFP fire extinguishers shall be replaced at least once every 3 years the time of hydrostatic testing .

Statement of Problem and Substantiation for Public Input

Extending the mandated agent replacement interval from 3 years to 5 years (to align with hydrostatic testing timing) will reduce unnecessary recharge of portable AFFF and FFFP fire extinguishers. It will also align the agent removal and recharge requirements that already exist with hydrostatic testing. Extending the mandated agent replacement interval will reduce unnecessary waste and equipment servicing while helping to reduce life cycle costs required for maintaining a foam/water fire extinguisher.

AFFF synthetic foam concentrate charges for fire extinguishers typically have biocide materials added to extend the foam solution's shelf life. There is no known negative foam performance related problems or history of hardware problems associated with properly charged pre-mix synthetic firefighting foam extinguishers within clean extinguisher cylinders using fresh potable water, as contained in equipment manufacturers' instructions.

At least one extinguisher manufacturer has performed testing of their units with extended replacement intervals and notes retention of original firefighting performance for six years (Question 8 at http://www.badgerfire.com/utcfs /ws-603/Assets/T104-0110.pdf).

8.3.1.1 The hydrostatic retest shall be conducted within the calendar year of the specified test interval. Hydrostatic retesting shall be performed prior to affixing a new certification tag that displays the same year in which the testing is due.

Statement of Problem and Substantiation for Public Input

The suggested verbiage is needed to help eliminate confusion among for the AHJ's. AHJ's, in particular, rely on a current certification tag on fire extinguishers as assurance that all of the required work has been performed prior to the tag being affixed to the fire extinguisher.

The year of manufacture is the point of reference for the need for periodic hydrostatic retesting. Since there is no month or day provided along with the year of manufacture on most fire extinguishers, some service providers are performing maintenance on fire extinguishers when maintenance is due, but not performing the hydrostatic re-test until later in the year or waiting until the following year.

For example, if a fire extinguisher is due for annual maintenance in January, as well as hydrostatic retesting in that same calendar year, the service provider may perform the maintenance only in January, without performing a hydrostatic retest at the same time. They will affix a new certification tag, and allow the extinguisher to go another 11 months or more, without testing it.

What makes it difficult for the AHJ's who are responsible for policing unscrupulous service providers is that they can't determine if a service provider will be back later within the same calendar year to complete the job and perform the hydrostatic retesting, or whether they actually missed testing it. The proposed changes, if accepted, would ensure that hydrostatic testing would be performed at the time of maintenance and before any new certification tag was affixed.

Public Input No. 294-NFPA 10-2014 [ Section No. A.5.4.2 ]

A.5.4.2 Most All buildings have Class A fire hazards. In any occupancy, there could be a predominant hazard as well as special hazard areas requiring supplemental protection extinguishers with ratings to match those hazards or additional extinguishers . For example, a hospital will generally have need for Class A fire extinguishers covering patient rooms, corridors, offices, and so forth, but will need Class B fire extinguishers in laboratories and where flammable anesthetics are stored or handled, Class C fire extinguishers in electrical switch gear or generator rooms, and Class K extinguishers in kitchens.

A.6.1.3.10 (NEW) In addition to providing storage, extinguisher cabinets provide protection for extinguishers and prevent accidental bumping. The cabinet cavity must be big enough to accommodate the extinguisher, so the extinguisher must be selected before selecting the cabinet. The final selection of the cabinet should allow adequate room for the extinguisher to be easily removed. Certain fire-rated cabinets are intended for installation into 1-hour and 2-hour fire-resistance-rated walls. They are specially constructed with gypsum board installed on the sides, top, bottom, and back. Cabinets that are not fire-rated make the entire fire-rated wall noncompliant, so only surface mounted cabinets or fire-rated cabinets are appropriate for installation in fire-resistance-rated walls.

A.7.3.3.1 Internal maintenance examinations are to be performed at intervals measured from the last internal examination. Other required internal examinations occur when an extinguisher is recharged or hydrostatically tested. An internal examination is to be conducted on or before the one year anniversary date of the previous internal examination. Persons performing maintenance operations usually come from two major groups:

(1) Fire extinguisher service agencies (2) Trained industrial safety or maintenance personnel

Fire extinguishers owned by individuals are often neglected because a periodic follow-up program is not planned. It is recommended that such owners become familiar with their fire extinguishers so they can detect telltale warnings during inspection that suggest the need for maintenance. When maintenance is indicated, it should be performed by trained persons having proper equipment. (See 7.1.2.2.) The purpose of a well-planned and well-executed maintenance program for a fire extinguisher is to maximize the following probabilities:

(1) That the extinguisher will operate properly between the time intervals established for maintenance examinations in the environment to which it is exposed (2) That the extinguisher will not constitute a potential hazard to persons in its vicinity or to operators or rechargers of fire extinguishers

Any replacement parts needed should be obtained from the manufacturer or a representative.

The following procedure permits rapid removal of the hose by one person without kinking of the hose and without obstruction of flow of the extinguishing agent:

(1) Form a loop over the hose supports [see Figure A.7.6.2(a)]. (2) Follow with a reverse loop so that the hose passes behind the loop [see Figure A.7.6.2(b)]. (3) Repeat steps (1) and (2) Continue making reverse loops until all hose is coiled on the support [see Figure A.7.6.2(c)]. (4) Adjust the coil so that the nozzle is in the downward position [see Figure A.7.6.2(d)]. Hose coiled in this manner pulls off free of twists. (5) Place the nozzle in the holder with the handle forward in the closed position [see Figure A.7.6.2(e)].

Public Input No. 323-NFPA 10-2015 [ Section No. A.7.10 ]

A.7.10 A number of states have regulations requiring an internal marking of an extinguisher that is used to verify if the verification-of-service collar is installed to show that an extinguisher has been depressurized, if the valve has been removed, and if a complete maintenance has been performed. The verification-of-service collar design also requires that the valve be removed before the collar can be attached to the extinguisher. The collar provides the authorities having jurisdiction with a more convenient visual proof that the extinguisher has been disassembled and that maintenance most likely has been performed. All extinguishers are to have the valve removed for hydrostatic testing and are to be subsequently recharged before they are returned to service. To be valid, the date on the verification-of-service collar should always be the same as or more recent than the date on the hydrostatic test label. Figure A.7.10 provides a guide to the design of a verification-of-service collar. Figure A.7.10 Design of a Verification-of-Service Collar.

C.3.2.1 1 The most popular type is the 2 ⁄2 gal (9.46 L) stored-pressure water fire extinguisher. These fire extinguishers are being used to replace inverting types of water fire extinguishers (soda acid and cartridge- operated water), which are no longer manufactured. An important advantage of the stored-pressure water type , as opposed to the inverting type, is its ability to be discharged intermittently. Some models are suitable for use at freezing conditions when charged as specified on the nameplate.

C.3.5.2 In general, bromotrifluoromethane (Halon 1301) fire extinguishers have features and characteristics similar to those of carbon dioxide fire extinguishers in that they are suitable for cold weather installation and leave no residue. Halon 1301 fire extinguishers are listed for Class B and Class C fires. Compared to carbon dioxide on a weight-of-agent basis, bromotrifluoromethane (Halon 1301) is at least as effective. When discharged, the agent is in the combined form of a gas/mist. To some extent, windy conditions or strong air currents could make extinguishment difficult by causing the rapid dispersal of the agent.

C.3.5.3 Fire extinguishers containing a mixture of Halon 1211 and Halon 1301 share properties of the other halogenated agent–type fire extinguishers, such as leaving no residue after use and minimizing thermal shock. The mixture of halogenated agents discharges in the form of a gas/mist, with the ratio of gas to mist increasing with higher ratios of Halon 1301 to Halon 1211. The discharge range likewise is affected by the ratio of Halon 1301 to Halon 1211, with the range decreasing as the proportion of Halon 1301 increases.

D.4.4.2 Bromochlorodifluoromethane / Bromotrifluoromethane (Halon 1211/1301) Mixtures. Fire extinguishers of this type are available in capacities from 1 lb to 20 lb (0.45 kg to 9 kg), having fire extinguishment ratings from 1-B:C to 4-A:80-B:C. The halogenated agent mixture is retained under pressure in a liquid state and is self-expelling. Some of these fire extinguishers are superpressurized with nitrogen. Upon actuation, the vapor pressure causes the agent to expand so that the discharge stream is in the form of a gas/mist. These extinguishers have a horizontal stream range of 3 ft to 18 ft (0.9 m to 5.5 m) that is not affected by wind as much as carbon dioxide and Halon 1301 are. Deep-seated Class A fires could need to be broken apart to effect complete extinguishment. On Class B fires, the discharge is applied in a side-to-side motion, progressing toward the back of the fire. (See Figure D.4.4.2 .) Figure D.4.4.2 Halon 1211/1301 Extinguishers.

D.4.5 Dry Chemical Types.

122 of 149 6/18/2015 3:43 PM National Fire Protection Association Report http://submittals.nfpa.org/TerraViewWeb/ContentFetcher?commentPara...

Dry chemical fire extinguishers (sodium bicarbonate, potassium bicarbonate, potassium bicarbonate urea base, bicarbonate urea base, or potassium chloride base) are ), are intended primarily for use on Class B and Class C fires. Dry chemical fire extinguishers (multipurpose ammonium phosphate base) are intended for use on Class A, Class B, and Class C fires. There are two methods whereby a dry chemical agent can be discharged from a fire extinguisher shell, depending on the basic design of the fire extinguisher. They are the cartridge/cylinder-operated method and the stored-pressure method. Regardless of fire extinguisher design, the method of agent application is basically the same. Stored-pressure fire extinguishers are available in capacities from 1 lb to 30 lb (0.5 kg to 14 kg) for hand fire extinguishers and 125 kg to 250 lb (57 kg to 113.5 kg) for wheeled fire extinguishers. Cartridge/cylinder-operated fire extinguishers are available in capacities from 4 lb to 30 lb (1.8 kg to 14 kg) for hand fire extinguishers and 45 lb to 350 lb (20 kg to 159 kg) for wheeled fire extinguishers. Dry chemical fire extinguishers are also available in nonrechargeable, nonrefillable types that contain the agent and expellant gas in a single, nonreusable, factory-filled container. Most dry chemical fire extinguishers having ratings of 20-B and less will discharge their contents in 8 seconds to 20 seconds. Fire extinguishers with higher ratings could take as long as 30 seconds. Therefore, since there is little time for experimentation, it is important that the operator be prepared to apply the agent correctly at the outset. All dry chemical fire extinguishers can be carried and operated simultaneously and can be discharged intermittently. The discharge stream has a horizontal range of 5 ft to 30 ft (1.5 m to 9.2 m), depending on fire extinguisher size. When used on outdoor fires, maximum effectiveness can be achieved when the direction of the wind is on the back of the operator. [See Figure D.4.5(a) and Figure D.4.5(b).] Figure D.4.5(a) Stored-Pressure Dry Chemical Extinguisher.

Figure D.4.5(b) Cartridge-Operated Dry Chemical Extinguisher.

Special long-range nozzles are available where potential fire-fighting conditions could require greater distance. These nozzles are also useful on pressurized gas or liquid fires, or where strong winds prevail. All dry chemical agents can be used at the same time that water (straight stream or fog) is being applied. The use of dry chemical fire extinguishers on wet energized electrical equipment (such as rain-soaked utility

123 of 149 6/18/2015 3:43 PM National Fire Protection Association Report http://submittals.nfpa.org/TerraViewWeb/ContentFetcher?commentPara...

poles, high-voltage switch gear, and transformers) can aggravate electrical leakage problems. The dry chemical, in combination with moisture, provides an electrical path that can reduce the effectiveness of insulation protection. The removal of all traces of dry chemical from such equipment after extinguishment is recommended. [See Figure D.4.5(c).] Figure D.4.5(c) Stored-Pressure Dry Chemical Extinguisher with Fixed Nozzle.

Fire extinguishers with a Class B rating can extinguish a fire involving combustible cooking media (vegetable or animal oils and fats). Only fire extinguishers having a Class K rating are recommended for use on cooking grease fires. D.4.5.1 Ordinary Dry Chemical Extinguishers (Class B and Class C Fires). Hand fire extinguishers of this type are available with fire-extinguishing ratings of 1-B:C to 160-B:C and as wheeled models having fire extinguishment ratings from 80-B:C to 640-B:C. The fire extinguishing agent used is a specially treated material in a finely divided form. Types of agents available include sodium bicarbonate base, potassium bicarbonate base, potassium chloride base, and potassium bicarbonate urea base. Some formulations of these agents are specially treated to be relatively compatible for use with air foam (mechanical foam). For use on flammable liquid fires, the stream should be directed at the base of the flame. Best results are generally obtained by attacking the near edge of the fire and progressing toward the back of the fire by moving the nozzle rapidly with a side-to-side sweeping motion. Care should also be taken not to direct the initial discharge directly at the burning surface at close range [less than 5 ft to 8 ft (1.5 m to 2.4 m)] because the high velocity of the stream can cause splashing or scattering of the burning material, or both. Although not listed for use on Class A fires, ordinary dry chemical can be used to rapidly knock down the flames. Once the flames are extinguished, the operator can kick or poke apart the fire debris, to assist and hasten the natural cooling of the burning embers. Hot spots or small areas that reignite can be controlled with short intermittent bursts of agent. Water should then be applied to extinguish burning embers or deep-seated hot spots. It is recommended that this method of extinguishment be attempted only if the operator has had training and experience in this technique. Fire extinguishers with a Class B rating can extinguish a fire involving combustible cooking media (vegetable or animal oils and fats). Only fire extinguishers having a Class K rating are recommended for use on cooking grease fires.

D.4.5.2 Multipurpose Dry Chemical Extinguishers (Class A, Class B, and Class C Fires). Fire extinguishers of this type contain an ammonium phosphate base agent. Hand fire extinguishers are available with fire extinguishment ratings of 1-A to 20-A and 10-B:C to 120-B:C, and wheeled models have fire extinguishment ratings of 20-A to 40-A and 60-B:C to 320-B:C. Multipurpose agents are used in exactly the same manner as ordinary dry chemical agents on Class B fires. For use on Class A fires, the multipurpose agent has the additional characteristic of softening and sticking when in contact with hot surfaces. In this way, it adheres to burning materials and forms a coating that smothers and isolates the fuel from air. When applying the agent, it is important to try to coat all burning areas in order to eliminate or minimize the number of small embers that could be a potential source of reignition. The agent itself has little cooling effect, and, because of its surface coating characteristic, it cannot penetrate below the burning surface. For this reason, extinguishment of deep-seated fires might not be accomplished unless the agent is discharged below the surface or the material is broken apart and spread out. Fire extinguishers with a Class B rating can extinguish a fire involving combustible cooking media (vegetable or animal oils and fats). Only fire extinguishers having a Class K rating are recommended for use on cooking grease fires.

Public Input No. 261-NFPA 10-2014 [ Section No. D.4.5.2 ]

D.4.5.2 Multipurpose Dry Chemical Extinguishers (Class A, Class B, and Class C Fires). Fire extinguishers of this type contain an ammonium phosphate base agent. Hand fire extinguishers are available with fire extinguishment ratings of 1-A to 20-A and 10-B:C to 120-B:C, and wheeled models have fire extinguishment ratings of 20-A to 40-A and 60-B:C to 320-B:C. Multipurpose agents are used in exactly the same manner as ordinary dry chemical agents on Class B fires. For use on Class A fires, the multipurpose agent has the additional characteristic of softening and sticking when in contact with hot surfaces. In this way, it adheres to burning materials and forms a coating that smothers and isolates the fuel from air. When applying the agent, it is important to try to coat all burning areas in order to eliminate or minimize the number of small embers that could be a potential source of reignition. The agent itself has little cooling effect, and, because of its surface coating characteristic, it cannot penetrate below the burning surface. For this reason, extinguishment of deep-seated fires might not be accomplished unless the agent is discharged below the surface or the material is broken apart and spread out.Fire extinguishers with a Class B rating can extinguish a fire involving combustible cooking media (vegetable or animal oils and fats). Only fire extinguishers having a Class K rating are recommended for use on cooking grease fires.

Statement of Problem and Substantiation for Public Input

ABC dry chemical extinguishers were never suggested for use on cooking media fires. It should also not be suggested that dry chemicals without a Class K rating be used to extinguish Class K fires.

Public Input No. 336-NFPA 10-2015 [ Section No. F.4.2 ]

F.4.2 The following types of extinguishers are considered obsolete and should be removed from service and replaced:

(1) Soda acid types (2) Chemical foam (excluding film-forming agents) (3) Vaporizing liquid Carbon Tetrachloride (4) Cartridge-operated water (5) Cartridge-operated loaded stream (6) Copper or brass shell fire extinguishers (excluding pump tanks) joined by soft solder or rivets (7) Extinguishers rated prior to 1955 and marked B-1, C-1 on the nameplate (8) Fire extinguishers not listed or labeled

Statement of Problem and Substantiation for Public Input

This section prohibits the use of all vaporizing liquid extinguishing agents. However, there are numerous vaporizing liquid agents i.e. Halon 1211 and Halotron 1 that are widely accepted and are in prevalent use today. Though Halon 1211 and Halotron 1 may be described as Halocarbons, they are still included in the broad category of "vaporizing liquid" agents. Leaving this section as is unnecessarily groups acceptable vaporizing liquids with those that are unacceptable, i.e. Carbon Tetrachloride. Those extinguishing agents that this section intends to obsolete should be specifically named.

Committee Statement

Resolution: FR-65-NFPA 10-2015 Statement: Number (3), as written, eliminates all vaporizing liquid extinguishing agents. There are currently numerous types of vaporizing liquid clean extinguishing agents in use today, i.e. Halon 1211 and Halotron 1. Though these agents may be categorized as Halogenated Agents, they still also fall under the broader general category of "vaporizing liquids".

Public Input No. 272-NFPA 10-2014 [ Section No. G.2 ]

G.2 Example. A fire extinguisher is rated and classified 4-A:20-B:C, which imparts the following information:

1 (1) It should extinguish approximately twice as much Class A fire as a 2-A-rated fire extinguisher [2 ⁄2 gal (9.46 L) water]. (2) It should extinguish approximately 20 times as much Class B fire as a 1-B-rated fire extinguisher. (3) It is suitable for use on energized electrical equipment.

Currently, laboratories classify fire extinguishers for use on Class A fires with the following ratings: 1-A, 2-A, 3-A, 4-A, 6-A, 10-A, 20-A, 30-A, and 40-A. Effective June 1, 1969, fire extinguishers classified for use on Class B fires have the following ratings: 1-B, 2-B, 5-B, 10-B, 20-B, 30-B, 40-B, 60-B, 80-B, 120-B, 160-B, 240-B, 320-B, 480-B, and 640-B. Ratings from 1-A to 20-A and 1-B to 20-B, inclusive, are based on indoor fire tests; ratings at or above 30-A and 30-B are based on outdoor fire tests. For Class B fires, it should be recognized that the amount of fire that can be extinguished by a particular fire extinguisher is related to the degree of training and experience of the operator. For fire extinguishers classified for use on Class C fires, no number is used, since Class C fires are essentially either Class A or Class B fires involving energized electrical wiring and equipment. Other than when being discharged from an extinguisher, water-based agents are conductive, and agent pooling after discharge might present additional hazard concerns. The size of the different suitable fire extinguishers installed should be commensurate with the size and extent of the Class A or Class B components, or both, of the electrical hazard being protected. For fire extinguishers classified for use on Class D fires, no number is used. The relative effectiveness of these fire extinguishers for use on specific combustible metal fires is detailed on the fire extinguisher nameplate. Fire extinguishers that are effective on more than one class of fire have multiple letter and number-letter classifications and ratings. The equivalency for Class B extinguishers rated under the rating classification system used prior to 1955 is given in Table G.2 . Table G.2 Class B Rating Equivalencies Extinguisher Type and Capacity Pre-1955 Rating Equivalency Foam (gal) 2 1 ⁄ 2 B-1 2-B 5 B- 1 5-B 17 B 10-B 33 B 20-B Carbon Dioxide (lb) Under 7 B-2 1-B 7 B-2 2-B 10 to 12 B-2 2-B 15 to 20 B-1 2-B 25 to 26 B-1 5-B 50 B-1 10-B 75 B-1 10-B 100 B 10-B Dry Chemical (lb) 4 to 6 1 ⁄ 4 B-2 2-B 7 1 ⁄ 2 B-2 5-B 10 to 15 B-1 5-B 20 B-1 10-B 30 B-1 20-B 75 and up B 40-B For SI units, 1 gal = 3.785 L; 1 lb = 0.454 kg. For extinguishers classified under the system used prior to 1955, the pre-1955 classifications of C, C-1, and C-2 are equivalent to the current C classification. Carbon dioxide extinguishers with metal horns do not carry any C classification.

Statement of Problem and Substantiation for Public Input

The ratings system prior to 1955 is outdated and has no effect on current standards; extinguishers manufactured prior to 1955 should be removed from service in the interest of public safety, as there have not been OEM parts available for decades.

H.2 Health and Safety Conditions That Affect Selection.

135 of 149 6/18/2015 3:43 PM National Fire Protection Association Report http://submittals.nfpa.org/TerraViewWeb/ContentFetcher?commentPara...

When a fire extinguisher is being selected, consideration should be given to the health and safety hazards involved in its maintenance and use, as described in the following items:

(1) For confined spaces, prominent caution labels on the fire extinguisher, warning signs at entry points, provision for remote application, extra-long-range fire extinguisher nozzles, special ventilation, provision of breathing apparatus and other personal protective equipment, and adequate training of personnel are among the measures that should be considered. (2) Although halogenated agent–type fire extinguishers contain agents whose vapor has a low toxicity, their decomposition products can be hazardous. When using these fire extinguishers in unventilated places, such as small rooms, closets, motor vehicles, or other confined spaces, operators and others should avoid breathing the gases produced by thermal decomposition of the agent. (3) Carbon dioxide fire extinguishers contain an extinguishing agent that will not support life when used in sufficient concentration to extinguish a fire. The use of this type of fire extinguisher in an unventilated space can dilute the oxygen supply. Prolonged occupancy of such spaces can result in loss of consciousness due to oxygen deficiency. (4) Fire extinguishers not rated for Class C hazards (e.g., water, antifreeze, loaded stream, AFFF, FFFP, wetting agent, and foam) present a shock hazard if used on fires involving energized electrical equipment. (5) When used in a small unventilated area, dry chemical fire extinguishers can reduce visibility for a period of up to several minutes. Dry chemical discharged in an area can also clog filters in air-cleaning systems. (6) A dry chemical fire extinguisher containing ammonium compounds should not be used on oxidizers that contain chlorine. The reaction between the oxidizer and the ammonium salts can produce the explosive compound nitrogen trichloride (NCl3). (7) Halogenated extinguishers should not be used on fires involving oxidizers, since they can react with the oxidizer. (8) Most fires produce toxic decomposition products of combustion, and some materials, upon burning, can produce highly toxic gases. Fires can also consume available oxygen or produce dangerously high exposure to convected or radiated heat. All of these can affect the degree to which a fire can be safely approached with fire extinguishers.

Table H.2 summarizes the characteristics of fire extinguishers and can be used as an aid in selecting fire extinguishers in accordance with Chapter 5. The ratings given are those that were in effect at the time this standard was prepared. Current listings should be consulted for up-to-date ratings.
