(2) Wood dust is regulated by OSHA as an organic dust under Particulates Not Otherwise Regulated (PNOR) or Inert or Nuisance Dust categories utilizing the PELs in Section n. Some States have incorporated provisions of the 1989 standard in their state plan; Additionally. OSHA has announced that tfaev may cite companies under the OSH Act General Duty Clause, under appropriate circumstances, for non-compliance with the

(3) The Company manufactures this product using locally available materials. The composition of wood types will vary depending on the location of the manufacturing facility and available wood species. The ACGM TLV for western red cedar is 0.5 mg/m3 inhalable parrjculate mass. The ACGIH TLV for all other wood species is 1.0 mg/m3 inhalable paiticulate mass. The Company does not intentionally use western red cedar in the manufacturing process. Various hardwoods are used at some manufacturing locations.

SECTION m - PHYSICAL PROPERTIES

DESCRIPTION

Composite panel product composed of resin, wax, boric acid and wood particles/fibers/lingo cellulosic fibers of varying percents (dependent on properties and thickness) pressed into panels of various sizes (normally 4 ft. X S ft.). Light tan to dark brown and may be colored due to the addition of wood coloring dye during manufacture.

PHYSICAL DATA

Boiling Point - Not Applicable Specific Gravity - < 1 Vapor Density - Not Applicable % Volatile* by Volume - Not Applicable Melting Point - Not Applicable Vapor Pressure - Not Applicable Solubility in Water (H20) (% BY WT.) - Insoluble Evaporation Rate (Butyl Acetate = 1) - Not Applicable pH - Not Applicable Appearance And Odor - Light to dark colored solid. Color and odor are dependent on the wood species and time since board was manufactured and if any dye is present

SECTION IV - FIRE AND EXPLOSION DATA

Flash Point - Not Applicable Auto Ignition Temperature - 425 - 475 degrees F Flammable Limits - Wood Panel, Piloted flame -500 degrees F. Fire Extinguishing Media - Water Spray, Carbon Dioxide Special Fire Fighting Procedures - Use Class A fire fighting procedures for an incipient fire. Fire-fighting procedures for wood products are well known. Water and Gass A foam should be considered. Seek professional fire fighting help as necessary. Unusual Fire And Explosion Hazards — This product does not present a fire or explosion hazard. Sawing, drilling, sanding, or machining this product could result in the creation of wood dust and or lingo-cellulosic fibers/dust Wood dust may present a strong to sever explosion hazard if a dust cloud contacts an ignition source. According to data contained in NFPA Standards, 0.04 ounce of wood flour per cubic foot of air is the minimum explosive concentration.

SECTION V - HEALTH HAZARD DATA

EXPOSURE, ACUTE AND CHRONIC

Wood Dust/Fiber: May cause nasal dryness, irritation and mucostasis. Coughing, wheezing, sneezing, sinusitis and prolonged colds have also been reported. Depending on wood species may cause respiratory sensitization and/or irritation. If irritation persists seek medical attention. Signs and Symptoms of Exposure to Wood Dost- Acute- May cause eye irritation, nasal dryness, irritation and obstruction. Certain species may cause allergic dermatitis to certain individuals. If irritation persists, seek medical attention. Chronic-Depending on species of wood, wood dust may cause allergic dermatitis from repetitive contact at elevated levels. Certain elevated levels and prolonged exposures to wood dust have been associated with nasal cancer. 1 ARC classifies wood dust, depending on species, as a carcinogen to humans (group 1). This classification is primarily based on studies showing an association between occupational exposure to wood dust and adenocarcinotna of the nasal cavities and paranasal sinuses. IARC did not find sufficient evidence of an association between occupational exposure to wood dust and cancers of the oropharynx, hypopharynx, lung, lymphatic and hematopoietic systems, stomach, colon or rectum. NTP classifies wood dust as a known human carcinogen.

Formaldehyde Gas/Vapor: May cause transient irritation of the skin, eyes, or respiratory system. If irritation persists seek medical attention. Signs and Symptoms of Exposure to Formaldehyde- Acute - May cause transient irritation of skin, eyes, or respiratory system. If irritation persists seek medical attention. Chronic - Numerous epidemiological studies have failed to demonstrate a relationship between formaldehyde exposure and nasal or pulmonary cancer or pulmonary diseases such as lung cancer and emphysema. Rats exposed to 14-ppm formaldehyde in laboratory studies developed nasal cancer. Exposure at 6 ppm did not develop statistically significant data linking formaldehyde to nasal cancer in rats. The NCI epidemiology study of 26,000 workers found little, if any, evidence linking formaldehyde exposure to cancer. The EPA has classified formaldehyde a B-l Probable Human Carcinogen. Formaldehyde is listed by the NTP as an animal carcinogen and is reasonably anticipated to be a human carcinogen. The IARC monograph lists formaldehyde as a group I carcinogen to humans. This IARC determination is based on the work product of a working group that concluded that sufficient evidence exists that formaldehyde causes nasopharyngeal cancer in humans. Nasopharyngeal cancer is rare in developed countries.

EXPOSURE AND PERSONAL PROTECTION INFORMATION

Engineering Controls- Wood Dust - Due to the potential explosive nature of wood dust/fiber when suspended in air, adequate precautions should be taken during pneumatic/conveyor moving, sawing, sanding, drilling, machining, etc. of wood products to prevent sparks or other sources of ignition near these activities. Provide adequate general and local ventilation to keep airborne contaminant concentration levels below the OS HA PEL. Employ good safety and personal hygisje practices. Formaldehyde - Provide adequate general and local ventilation to maintain exposure levels below the OSHA PEL. Employ good safety and personal hygiene practices. Respiratory protection- Use of a NIOSH/MSHA approved respirator when the permissible exposure limits to formaldehyde and/or wood dust may be exceeded. Eye Protection- Wear side shield safety glasses or goggles during handling or remanufacturing this product Skin Protection- Wear gloves when handling this product. Wear protective clothing/outer garments as needed to prevent exposure. General Hygiene- Practice proper personal hygiene.

EMERGENCY FIRST AID PROCEDURES

Inhalation- Remove to fresh air. If irritation or other symptoms persist, seek medical attention. Eyes- Wash material from eyes with clean running water. If irritation persists, seek medical attention. Skin - If skin is abraded, utilize proper first aid procedures and seek medical attention. Ingest ion - N/A

TOXICOLOGICAL

Wood Dust- OSHA hazard rating for oral ingestion is moderately toxic for both softwood and hardwood. The OSHA suggested oral lethal dose is 0.5 to 5 g/kg or about 1 pound (dry) for an approximately 150 pound person. Activities that could generate wood dust (sawing, drilling, grinding, sanding, machining, etc.) should be avoided and or dust control methods employed. If wood dust is generated, steps should be taken to reduce exposure. Good Industrial Hygiene procedures should be implemented.

Formaldehyde- OSHA hazard rating for systemic acute and chronic exposures is highly toxic. Concentrated formaldehyde when exposed to the intact skin causes irritation. Some exposure panels exposed to concentrations of approximately 0.3 ppm have failed to produce irritation. Odor threshold for some data sources indicate an odor threshold of 0.3 ppm. All applicable provisions of the OSHA formaldehyde standard should be implemented. Good Industrial Hygiene procedures should be implemented.
