Compressed gases include:
Compressed gases can pose both physical and health hazards. The pressure in a gas cylinder makes it a potential rocket that can punch through walls. The gases frequently represent inherent hazards independent of pressure such as flammability, corrosivity, toxicity, and excessive reactivity. Gas released from a cylinder may also have the potential to asphyxiate nearby workers by displacing air in a space.
Compressed gas cylinders must be handled with caution at all times. It is particularly important to protect cylinder valves from breakage. The following are two sets of handling instructions, one for gas cylinders in general and the other for poisonous and flammable gases.
Flammable and poisonous gases are subject to fire code regulations. Notify EH&S before ordering flammable or poisonous gas cylinders to determine the proper safety and control measures as well as permit requirements.
|Flammable gases include:
||Poisonous gases include:
All gas cylinders must be stored upright and firmly secured to a wall at two points. Poisonous and flammable gases must be segregated from other gases and stored in an adequately ventilated area.
Leaking flammable or poisonous gas cylinders must be vented at a rate not to exceed 10% of the explosion limits or IDHL (Immediately Dangerous to Health and Life).
Store poisonous gas cylinders in a gas cabinet or chemical fume hood.
All empty cylinders must be clearly marked Empty and must be collected by the vendor.
