At tower exposure levels, this significant effect was not observed. The normal clearance mechanisms of the lungs may have been overwhelmed at the 250mg/M3 exposure level, and this may have contributed to the o c c u r e n c e of capprcinogenicity.

The International Agency for Research on Cancer considers crystalline silica to have limited evidence of carcinogenicity in humans and sufficient evidence in experimental animals (IARC Group 2A). -- SECTION : IV FIRST',. ---ASD AN® EMERGENCY.: PROCEDURE --- SWALLOWING If swallowed do not induce vomiting. Call poison control center, hospital emergency room or physician immediately. INHALATION Remove to fresh air immediately. If breathing has s t o p p e d I give artifi - cial EYE respiration. Keep warm and quiet. Get medical attention immediately. Flush with large amounts of water, lifting upper and lower lids occasional - SKIN ty' Continue for at Least 15 minutes. Get medical attention. Remove contaminated clothing. Wash affected area with soap and water. obtain medical attention if irritation persists. NOTES TO PHYSICIAN Any treatment that might be required for overexposure should be directed at the control of symptoms and the clinical conditions. _- - SECTION �-PHYSICAL DATA BOILING RANGE 1 DEG F ( 17 DEG.C. > TO 289 DEG.

Symptoms may not be immediately apparent. Obtain medical attention. - .- WARNING! FLAMMABLE. SPECIAL FIRE FIGHTING PROCEDURES Water may be ineffective, but may be used to cool exposed containers to prevent pressure build-up and possible auto -ignition or explosion when exposed to extreme heat. If water is used, fog nozzles are preferable. STABILITY Normally stable. CONDITIONS TO AVOID Avoid excessive heat (>100 F (38 C) and sources of ignition. INCOMPATABILITY (MATERIALS TO AVOID) Strong acids or alkaline materials. HAZARDOUS DECOMPOSITION PRODUCTS Burning, including when heated by welding or cutting, wilt produce smoke, carbon monoxide and carbon dioxide.
