Water soluble.
Fire Hazard
Special Hazards of Combustion Products: Toxic fumes

Behavior in Fire: Can emit toxic metal fumes and oxides of sulfur. (USCG, 1999)
Health Hazard
INHALATION: Joint and muscle pains, headache, dizziness, and insomnia. Weakness, frequently of extensor muscles of hand and wrist (unilateral or bilateral). Heavy contamination - Brain damage. Stupor progressing to coma - with or without convulsion, often death. Excitation, confusion, and mania less common. Cerebrospinal pressure may be increased. INGESTION: Abdominal pain, diarrhea, constipation, loss of appetite, muscular weakness, headache, blue line on gums metalic taste, nausea and vomiting, joint and muscle pain. (USCG, 1999)
