3. HAZARDS IDENTIFICATION
Feldspar is a naturally occurring anhydrous, inorganic, igneous rock. It is a complex aluminum silicate containing varying amounts of sodium, potassium, and calcium. Feldspar contains crystalline silica levels of 6 to 10%.
CARCINOGENICITY: This product contains crystalline silica. Repeated, prolonged inhalation of dust may cause delayed lung injury which may result in silicosis or pneumoconiosis. The International Agency For Research On Cancer
in its publication, “IARC Monographs On the Evaluation Of The Carcinogenic Risk To Humans – Silica, Some Silicates, Coal Dust and Para-aramid Fibrils” - Volume 68, 1997, has concluded that there is sufficient evidence of the carcinogenicity of crystalline silica in humans, and has, therefore, classified crystalline silica in, Group 1, Carcinogenic to Humans. The National Toxicology Program’s (“NTP’s”) Ninth Annual Report on Carcinogens 2000, lists crystalline silica (respirable) as a substance which is known to be a human carcinogen. In humans, a number of studies have found an association between lung cancer and
exposure to dust containing respirable crystalline silica. In many of these studies, though not all, lung cancer risks were elevated and could not be explained by confounding factors such as cigarette smoking or arsenic or random inhalation. While the IARC
working group concluded there was sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica in the
form of quartz or crystobalite, it noted that carcinogenicity in humans was not detected in all circumstances studied.
. Note: The state of California requires the following statement:
4. FIRST AID MEASURES
SKIN CONTACT ABSORPTION: Inflammation from contact with open cuts may occur. Wash thoroughly with water.
INHALATION: Short Term: Shortness of breath, coughing associated with inhalation of dust. Long Term: May cause silicosis, a chronic disease of the lungs marked by acute fibrosis; may cause cancer. If inhalation occurs move to fresh air, consult physician and/or obtain competent medical assistance as necessary.
EYE CONTACT: Wash eyes with large amount of water or saline solution. If irritation or redness develops, get medical attention.
INGESTION: Consult physician and/or obtain competent medical assistance
5. FIRE-FIGHTING MEASURES
Feldspar is not flammable.
6. ACCIDENTAL RELEASE MEASURES
Feldspar waste is not reactive, flammable or biodegradable. Use conventional means; e.g. sweeping, vacuum, etc.
7. HANDLING AND STORAGE
Avoid dust formation. Keep container tightly closed.
8. EXPOSURE CONTROL/PERSONAL PROTECTION

Crystalline Quartz Crystalline Quartz Crystalline Quartz
RESPIRABLE 0.1 mg/m3 (TWA-TLV) RESP. 0.025 mg/m3 (TWA-TLV) RESP. 0.05 mg/ m3 (TWA-TLV)
RESPIRATORY PROTECTION: Use NIOSH/MSHA/OSHA approved dust respirator if dust is present.
VENTILATION: Local exhaust required for dust removal. Refer to OSHA 1910.24, ASTM, and/or ANSI standards. Do not
exceed OSHA PEL or ACGIH TLV.
PROTECTIVE GLOVES & EYE PROTECTION: Impermeable gloves and Eye protective glasses are recommended.
NIOSH recommends against wearing contact lenses when working with crystalline silica.
