Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus; safety goggles; Symptoms Following Exposure: Inhalation may cause irritation of nose,
dizziness, depression. Moderate irritation of eye with corneal injury possible. Irritates skin and may
cause blisters; General Treatment for Exposure: INHALATION: remove victim to fresh air, keep him
warm, and get medical help promptly; if breathing stops give artificial respiration. INGESTION:
induce vomiting only upon physician's approval; material in lung may cause chemical pneumonitis.
