Description

Oxygen is supplied in high-pressure cylinders and is a colourless, odourless and tasteless gas.

Main hazards

Oxygen is not flammable but supports combustion. Oxygen enrichment of the atmosphere, even by a few per cent, considerably increases the risk of fire. Materials not normally combustible in air may burn vigorously or even ignite without any apparent reason in enriched air

Typical Uses

• Oxy-Acetylene welding
• Flame cleaning
• Oxy cutting
• Flame heating
• Flame hardening
• Water treatment
• Chemical reactions requiring increased oxidation rates

Cylinder dimensions are approximate – variations may occur due to manufacturing tolerances

Height includes the valve

Container sizes may vary from state to state

Storage and handling

• Store oxygen cylinders away from combustible materials.
• Ensure all cylinders are correctly labelled in accordance with Australian Dangerous Goods Code (Transport)
• Protect cylinders and particularly the valve from physical damage whether cylinder is full or empty.
• Store cylinders in a cool, well ventilated, spark free area below 45°C.
• External storage is preferred.
• Cylinders should never be carried or stored in unventilated areas, vans, cars, garages etc.
• Close valves when not in use and when empty, check regularly for leaks.
• If valve is damaged, do not attempt to operate.
• If valve does not operate by hand, return cylinder to supplier (attach a faulty cylinder tag).

N.B. Only regulators, manifolds and ancillary equipment, rated for the appropriate pressure and compatible with the relevant gas, shall be connected to or downstream of these cylinders.

In case of leaks

• Shut off all engines, electrical equipment and other sources of ignition.
• No smoking or naked lights.
• If possible, use emergency equipment stops.
• Stops leaks if possible, especially in enclosed or inadequately ventilated rooms. Move people from area.
• Check all lines and equipment for leaks, with periodic rechecks. All fittings and connections should be properly fitted.
• If leak continues, move cylinder to a safe area and allow to empty.
• Return empty cylinders and pack to supplier with a note to confirm the leak occurred
• Notify emergency services if required
