 Emergency treatment and disposal method
Emergency treatment of leakage
Isolate the leaking contaminated area and restrict access. Cut off the fire. Emergency responders are advised to wear self-contained breathing apparatus and fire protection clothing. Do not contact the leakage directly. Small leakage: mix with sand, dry lime or soda ash. Collect in a dry, clean, covered container using a sparkless tool. Move to a safe place. Large leakage: cover with plastic cloth and canvas to reduce flying. Liaise with relevant technical department to determine removal method.
Extinguishing method
Do not use water or foam to extinguish fire. Carbon dioxide doesn't work either. Use dry graphite powder or other dry powder (such as dry sand) to extinguish the fire.
