Part six: Accidental Release Measures

Emergency treatment: Isolate the contaminated area and restrict the access. It is suggested that emergency treatment person should wear dust masks (full face masks) and gas protective clothing. Avoid dust, sweep it carefully, put it in a bag and transfer to a safe place. In case of large leakage, cover with plastic cloth and canvas. Collect and recycle or transport to the waste disposal site for disposal.

Part 7: Handling and Storage

Operational precautions: closed-loop operation and local exhaust ventilation. Operators must be specially trained and strictly obey the operation rules. It is suggested that the operators should wear self-priming filter dust masks, chemical safety glasses, anti-poison penetration work clothes and rubber gloves. Avoid dust generation. Avoid contact with reducing agent and alkali metal. Handle with care to prevent package damage. Equipped with leakage emergency treatment equipment. The empty container may contain harmful substances.

Storage precautions: store in cool and ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from reducing agent, alkali metal and edible chemicals, and mixed storage is not allowed. The storage area should be equipped with suitable materials to contain the leakage.
