edit
Hazardous characteristics: strong oxidant.Contact with organic substances may cause combustion.Toxic gas is released due to high thermal decomposition.
Extinguishing method: firefighters must wear full body fire and gas protective clothing and extinguish the fire upwind.When putting out a fire, try to move the container from the fire site to an open place.Then select appropriate extinguishing agent to extinguish the fire according to the cause of fire.
Leakage emergency treatment
Announce
edit
Isolate the leakage contaminated area and restrict access.It is recommended that emergency treatment personnel wear dust masks and anti-corrosion and gas protective clothing.Do not touch the leakage directly.
Small amount of leakage: cover with dry sand, vermiculite or other inert materials.Collect in a closed container with a clean shovel.
Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.
Handling and storage
