what is property of gas in a canister should be stored in cool areas
Answers
Answer:
AS4332-2004 - The storage and handling of gases in cylinders recommends that wherever possible, compressed gases in cylinders should be stored outside. This blog looks at three hazards which are the primary reasons that gas cylinders stores should be isolated away from the main worksite, buildings, operations and production areas. We’ll also outline additional control measures specified in the Standard to ensure your gas cylinder stores reach 100% safety compliance.
Asphyxiation Hazards
With the exception of oxygen, any leaking gas under pressure is a potential asphyxiation hazard. The air we breathe is made up of 21% oxygen, 78% nitrogen, and 1% mix of other gases. When another gas (not oxygen) is leaked into the atmosphere it will displace the oxygen, and reduce the overall oxygen content in the air. When this happens outside, very often the leaked gas dissipates quickly and the gas percentages in the air remain at safe levels.
But cylinders stored indoors (and especially within confined spaces) present an increased asphyxiation risk as pressurised gas leaking from a cylinder can quickly fill a room. Once oxygen levels in a room fall below 18% anyone entering the area is at high risk of cognitive impairment, collapse, brain damage and death from lack of oxygen.
The standard has a number of requirements that address asphyxiation hazards, these include:
