Fire-fighting measures

Fire fighting method: Move the container from the fire scene to an open place as much as possible. Keep the fire container cool by spraying water until the fire is over. If the container in the fire scene has changed color or produces sound from the safety relief device, it must be evacuated immediately.

Packaging, storage, transportation

Packed in paint bucket, 180kg/drum, stored in a cool and ventilated warehouse. Keep away from fire and heat sources. The temperature of the warehouse should not exceed 37℃. Keep the container tightly closed. should be kept away from oxidizer, do not store together. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that easily generate sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials.
