Section III - Hazardous Information

Long term chronic airborne exposure may cause lung disease or aggravate any pre-existing respiratory condition unless proper respiratory protection is employed. Prolonged, frequent direct skin contact may lead to skin dermatitis. Acute or short-term airborne exposure in excess of the exposure limits may irritate the nasal passages and respiratory tract. Acute exposure to the skin or eyes may lead to irritation.

Section IV - First Aid Measures
Eyes		Flush eyes with clean water for at least 15 minutes. Consult a physician if irritation persists.
Skin		Wash thoroughly with soap and water. Consult a physician if irritation persists.
Inhalation		If overexposure symptoms are noticed, remove to fresh air. Do not permit exposures in excess of the exposure limits without use of proper controls including appropriate respiratory protection.
Ingestion		Unlikely to occur, however, if product is ingested, contact physician or poison control center immediately. Do not induce vomiting unless instructed to do so by medical personnel.

Section V - Fire Fighting Measures
Flammable Properties	None
Extinguishing Media	Use standard fire fighting agents.
Fire Fighting Instructions	None
Unusual Fire & Explosion Hazards	None

Section VI - Accidental Release Measures
Small or Large Spill		Product is normally supplied as 60 mm briquettes and/or smaller particles (in the case of Pro-Foam) including fines present due to mechanical actions while shipping and handling. Pick up or shovel and place in a container. Dampen material, if desired, to minimize the possible generation of airborne dust.

Section VII - Handling and Storage

Product is normally supplied as 60 mm briquettes and smaller particles including fines present due to mechanical actions while shipping and handling. Store in a dry place away from extreme heat or open flames. Use proper practices when transporting.

Section VIII - Exposure Controls/Personal Protection
Engineering Controls		Use adequate local and/or general ventilation to maintain exposures below the exposure limits (See Section II) including when initially burning in.
Respiratory Protection		Use NIOSH approved respirator for mineral dust when working with material.
Eye Protection		Use safety glasses with side shields to avoid eye contact.
Skin Protection		Wear impervious gloves along with long sleeve cotton shirts and long leg cotton pants to avoid or minimize direct skin contact and possible abrasion. Cleanse exposed skin with soap or hand cleaners as soon after contact as practical.
Other		Safety shoes should be worn to prevent foot injury from accidentally dropped material.

Section IX - Physical and Chemical Properties
Appearance	Black Solid
pH Level	N/A
Boiling Point	N/A
Odor	None
Solubility in Water	None
Melting Point	N/A
Specific Gravity	1.5 - 2.0

Section X - Stability and Reactivity

Product is stable under normal conditions of use, storage and transportation.

Section XI - Toxicological Information

No toxicological data is available for the blended product.

Calcium silicate is identified as a nuisance dust from an inhalation standpoint. It may irritate the eyes, skin and respiratory system. No LC50 or LD50 data is available at this time. Not listed as a carcinogen by NTP, IARC or OSHA.

Anthracite Coal is a respiratory toxicant. Prolonged, chronic exposure in excess of the exposure limits (See Section II) may result in pneumoconiosis, bronchitis, and emphysema. Coal dusts with greater than 5% crystalline silica present will react in the lungs similar to quartz. Crystalline silica has been designated as a Group I carcinogen by IARC. Chronic airborne exposure to crystalline silica in excess of the exposure limits (See Section II), may lead to silicosis, a disabling lung disease characterized by the formation of silica-containing nodules of scar tissue in the lungs.

Magnesium Oxide has no available LC50 or LD50 data. Not listed as a carcinogen by NTP, IARC or OSHA. MgO is generally considered as a nuisance dust from an inhalation standpoint.

Section XII - Ecological Information

Not Available

Section XIII - Disposal Considerations

As supplied, product may be disposed of in an approved landfill, in accordance with federal, state, and local regulations. Supplier can make no statement concerning disposal of used product, since product may become contaminated by hazardous materials during use.

Section XIV - Transportation Information
U.S.A. DOT	Not Required
Canadian TDG Hazard Class & PIN	Not Required

Section XV - Regulatory Information
TSCA Status		All components listed.
Canadian DSL		All components listed.
SARA Title III, Section 313		Does not apply to product�s components.
California Proposition 65		This product contains a chemical known by the State of California to cause cancer.
