Inhalation: Rapidly leave the scene to place with fresh air. Keep airway patency. Make artificial respiration if necessary and take medical treatment.

Protection

Respiratory protection: In high concentration air, wear gas mask. Emergency rescue or escape, wear self-contained breathing apparatus.
Eye protection: Wear chemical safety glasses.
Protective clothing: Wear appropriate protective clothing.
Hand protection: Wear anti-chemical gloves.

Leakage treatment

Isolate leakage polluted area, set warning signs around. Suggest emergency personnel wear gas mask, chemical protective clothing and do not direct contact with leakage. Mix with sand, dry lime or soda ash, collect in dry and covered container with clean shovel and move to waste disposal site. Also can rinse with a lot of water. Put the diluted washing water to waste water system. For large leakage, abandon after recycling or biosafety disposal.

Storage and transportation

Stored in a cool and ventilated warehouse. Away from fire, heat source and direct sunlight. Keep container sealed. Keep separate from oxidants and alternate chemical materials. Handle gently to avoid damage of packaging and container. Pay attention to personal protection in packing and handling operations.
