Health Hazards Information -Recommended Personal Protective Equipment: Chemical safety goggles
and (for those exposed to unusually dusty operations) a respirator such as those approved by the U.S.
Bureau of Mines for “nuisance dusts”; Symptoms Following Exposure: Eye and skin irritation; General
Treatment for Exposure: INHALATION OF DUST: remove from further exposure and call a doctor.
SKIN: wash with plenty of water. EYES: flush with clean running water an eye wash fountain for at
least 15 min. And get medical attention; Toxicity by Inhalation (ThreshoZdLimit Value): Not pertinent;
Short-Tern Exposure Limits: Not pertinent; Toxicity by Ingestion: Data not available; Late Toxicity:
None; Vapor (Gas) Irritant Characteristics: None; Liquid or Solid Irritant Characteristics: Minimum
hazard. If spilled on clothing and allowed to remain, may cause smarting and reddening of the skin;
Odor Threshold: Not pertinent.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (%): Not flammable; Fire
Extinguishing Agents: Dry powder; preferably allow fire to burn out; Fire Extinguishing Agents Not

causes irritation of upper respiratory system. Dust irritates eyes and skin. Ingestion causes abdominal
pain, nausea, vomiting, diarrhea, pallor, shortness of breath, unconsciousness; General Treatment for
Exposure: INHALATION: remove to fresh air. EYES: flush with water for 15 min. SKIN: flush with
water. INGESTION: induce vomiting and get medical attention; Toxicity by Inhalation (ThresholdLimit
