Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out.
Combustible material; may burn but does not ignite readily.
Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
May emit toxic hydrogen chloride and phosgene gases in fire.
Prolonged or repeated skin contact may cause dermatitis.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May be harmful if swallowed.
May cause respiratory tract irritation.
Causes skin irritation. Prolonged exposure may result in skin burns.
Causes eye irritation and possible burns.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
