Risk overview

Acute:Asphyxia caused by inhalation. If the oxygen content necessary for life in the air is reduced, exposure to anoxic(<19.5%)can cause dizziness, nausea, vomiting, loss of consciousness and death. Eye and skin contact have no adverse effects.

 

Chronic: Insufficient oxygen supply will affect the heart and the nervous system

 

Environmental hazard: None

 

Danger of explosion: When exposed to high heat or flame, the pressure in the cylinder will rise, and most of the cylinders are designed to release the high pressure gas from the rupture disk of the bottle valve. If the rupture disk fails, it can cause the explosion.

Fire control measures

Hazard characteristics: pressure in cylinders increases when exposed to high heat or flame. most cylinders are designed to release high pressure from the cylinder valve rupture

Gas, if the rupture fails, can cause an explosion.Harmful combustion products: none

Fire Extinguishing method: suitable for fire extinguishing source

Fire extinguishing agent: non - combustible and non - combustible, use suitable fire extinguishing agent

Fire precautions: if feasible, move cylinders out of the fire zone or use water mist to cool them. Emergency personnel need SCBA

Emergency treatment of leakage

Emergency treatment: isolate all personnel from the leakage area, conduct ventilation and ventilation in the area and monitor oxygen content, and use SCBA

Elimination method: allow emission to the atmosphere
