Health Hazards Information - Recommended Personal Protective Equipment: Dust mask, gloves,
goggles; Symptoms Following Enposure: Excessive inhalation of dust may cause irritation of lungs and
delayed symptoms similar to those observed after ingestion. Dust irritates eyes and skin and may be
absorbed through skin on prolonged exposure, ingestion causes irritation of mouth and stomach;
inflammation of kidney and liver develops 1 to 4 days after exposure; General Trearment for Exposure:
INHALATION: remove victim to fresh air. EYES: Hush with water for at least 15 min.: see physician
if irritation persists. SKIN: wash thoroughly with soap and water. INGESTION: administer large doses
