Vi. Emergency treatment and disposal methods

1. Emergency treatment of leakage

Wear self-contained breathing apparatus and overalls. Cut off the air supply. Exhaust (indoor) or strong ventilation (outdoor). The leak container can no longer be used and must be cleared by technical treatment

The gas that's left over.

2. Protective measures

Respiratory protection: Wear a gas mask when the concentration in the air is high. In case of emergency or evacuation, it is recommended to wear self-contained breathing apparatus.

Eye protection: Generally no special protection is required.

Physical protection: Wear work clothes.

Hand protection: Generally no special protection is required.

Other: Avoid high concentration inhalation.

3. First aid measures

Inhalation: Remove from site to fresh air. Give oxygen for dyspnea. When respiration stops, give artificial respiration immediately. Seek medical attention.

Fire extinguishing method: cut off the air source. Spray water to cool the container and move it away from the fire to an open area if possible. Misty water.
