Fire-fighting measures

Spray water to cool the container, and move the container from the fire scene to an open place if possible. If the container suddenly makes an abnormal sound or appears abnormal, it should be evacuated immediately. Extinguishing agent: foam, carbon dioxide, dry powder, sand, water fire is ineffective

Emergency treatment

Eye contact: Lift the eyelid, rinse with running water or normal saline, and seek medical attention

Inhalation: quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. Breathing and heartbeat stop, immediately perform cardiopulmonary resuscitation. Seek medical attention
