Oxidizing agents, acids, alkalis
Fire fighting methods Fire extinguishing with water is not effective, but water can be used to keep the container cool in the fire.

Storage and transportation considerations

Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 °C. Keep the container sealed. It should be stored separately from oxidants, acids and alkalis, and should not be mixed. Explosion-proof lighting and ventilation facilities are used. It is forbidden to use mechanical equipment and tools that are prone to sparks.

first-aid

Quickly leave the scene to the fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.

Leakage emergency treatment

Quickly evacuate personnel from the contaminated area to a safe area, and conduct isolation to strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear anti-static overalls. Cut off the source of the leak as much as possible. Prevent entry into restricted spaces such as sewers and flood drains
