Health Hazards Information - Recommended Personal Protective Equipment: Gloves, goggles,
respirator; Symptoms Following Exposure: The general symptoms are those of mercury poisoning,
developing rapidly after ingestion but more slowly after low repeated exposures. Contact with eyes
causes irritation and ulceration. Skin contact may cause dermatitis. Ingestion causes pain, vomiting,
ulceration of mouth and stomach, kidney failure, metallic taste, pallor, and rapid, weak pulse; General
Treatment forfiposure: Have physician treat for mercury poisoning. EYES or SKIN: flush with water.
