Health Hazards Information - Recommended Personal Protective Equipment: Safety glasses or face
shield, dust-type respirator, rubber gloves; Symptoms Following Exposure: Inhalation causes irritation
of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes (particularly
by dust) causes irritation and possible transient corneal injury. Contact of solid with dry skin causes
mild irritation, even a superficial bum; General Treatment for Exposure: INHALATION; move to fresh
air, if discomfort persists, get medical attention. INGESTION; give large amounts of water; Toxicity
by Inhalation (Threshold Limit Value): EYES: promptly flood with water and continue washing for at
least 15 min.; consult an ophthalmologist. SKIN: flush with water; Short-Term Exposure Limits: Data
