Isolate the contaminated area and restrict access. It is recommended that emergency handling personnel wear dust masks (full face masks) and anti-gas clothing. Do not contact the leakage directly. Do not let the leakage come into contact with reducing agent, organic substance, flammable substance or metal powder.
Small leakage: wash with a large amount of water, dilute the water and put it into the wastewater system.
Large leakage: cover with plastic cloth and canvas. Then it is collected and recycled or transported to the waste treatment site for disposal.
