Handling and storage:
Operating precautions: closed operation and local exhaust. Prevent dust from being released into the workshop air. Operators must receive special training and strictly abide by operating procedures. It is recommended that operators wear self-priming filter-type dust masks, chemical safety glasses, rubber acid and alkali-resistant clothes, and rubber acid and alkali-resistant gloves. Avoid dust generation. Avoid contact with oxidants and alkali. Provide leakage emergency treatment equipment. The emptied container may contain harmful substances.
Storage precautions: store in a cool and ventilated warehouse. Keep away from kindling and heat sources. Prevent direct sunlight. The package must be sealed and free from moisture. It shall be stored separately from oxidant and alkali, and mixed storage is prohibited. The storage area shall be equipped with suitable materials to contain leakage. It is easy to be oxidized in the air, so it must be used and prepared in the experiment.
Monitoring method:
Engineering control: closed operation and local exhaust.
Respiratory system protection: when the dust concentration in the air exceeds the standard, the self-priming filter dust mask must be worn. In case of emergency rescue or evacuation, air respirators shall be worn.
Eye protection: wear chemical safety glasses.
Body protection: wear rubber acid and alkali-resistant clothing.
