Emergency Response

Leak Emergency Response

Wear a self-contained respirator and work clothes. Cut off the gas source. Ventilation convection, dilution and diffusion. Move the leaking container to an open area, pay attention to ventilation. Leaky containers cannot be reused and must be treated technically to remove any remaining gas.

Protective Measures

Respiratory Protection: When the concentration in the air is high, a gas mask should be worn. In case of emergencies or evacuation, it is recommended to wear a self-contained respirator.

Eye Protection: No special protection is generally required.

Body Protection: Wear work clothes.

Hand Protection: No special protection is generally required.

Other: Avoid high concentration inhalation.

First Aid Measures

Inhalation: Remove from the scene to fresh air. Lie down and rest. Keep warm. Seek medical attention.

Fire Fighting Methods: Cut off the gas source. Spray water to cool the container, and if possible, move the container from the fire scene to an open area. Water spray.
