        Can react violently with acid-like substances.

Combustion (decomposition) products: acetylene, carbon monoxide, carbon dioxide.

        First Aid measures Skin Contact: Immediately remove contaminated clothing and rinse for at least 15 minutes with plenty of flowing water.

It is recommended that emergency handlers wear a self-pressurized breathing device and wear chemical protective clothing. Do not contact the leaking material directly. Small leakage: mixed with sand, dry lime or soda ash. Use no spark tool to collect in a dry, clean, covered container and transfer to a safe place. Large leaks: covered with plastic sheeting and canvas.

Liaise with relevant technical departments to determine the clearance method. Fire extinguishing method: Prohibit water or foam to extinguish fire. Carbon dioxide is also ineffective. Dry graphite powder or other dry powder (such as dry sand) shall be used for extinguishing.
