FIRE
AND EXPLOSION HAZARD DATA: Contains "free silica". Prolonged,
repeated, inhalation of restorable silica dust may cause silicosis
or chronic fibrotic lung disease. Follow OSHA safety and health
standards or as amended. AVOID BREATHING RESPIRABLE DUSTS FROM
THESE PRODUCTS.
REACTIVITY
DATA:
Stability - Stable Decomposition - Will not occur Incompatibility

SPILL
OR LEAK PROCEDURES:
AVOID BREATHING RESPIRABLE DUST OVER EXTENDED PERIOD. Sand and
gravel may be disposed of in landfill operation or other areas
where local regulations permit.
SPECIAL
PROTECTION INFORMATION: Follow current OSHA safety and health
standards or as amended, if exposure limits to respirable dust
are likely to be exceeded. Use an OSHA approved respirator.
SPECIAL
PRECAUTIONS: Avoid respiration of silica dust over an extended
period of time. Use an OSHA approved respirator if exposure limits
to respirable dust are likely to be exceeded. See OSHA safety
and health standards to determine exposure limits.
CARCINOGENICITY:
In February 1992, the National Toxicology Program (NTP), an agency
of the U.S. Department of Health and Human Services, listed "respirable
crystalline silica" in its 6th Annual Report on Carcinogen. In
1987, the International Agency for Research on Cancer (IARC) in
its publication of Monograph 42 concluded that there is sufficient
evidence of the carcinogenicity of crystalline silica to experimental
animals, and there is limited evidence of the carcinogenicity
of crystalline silica to humans.
