Quickly leave the scene to the fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. | |||||||||||||||
|
Leakage emergency treatment |
Quickly evacuate personnel from the contaminated area to a safe area, and conduct isolation to strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear anti-static overalls. Cut off the source of the leak as much as possible. Prevent entry into restricted spaces such as sewers and flood drains | |||||||||||||||
