Description
Acetylene is a colourless, highly flammable gas which has a distinct odour.

Main hazards
Highly flammable and forms an explosive mixture with air. Leaks may catch fire without apparent source of ignition. High concentration of gas may cause dizziness, drowsiness and/or suffocation.

Typical Uses

• Oxy-Acetylene welding
• Cutting localised
• Heating
• Flame hardening
• Atomic absorption spectroscopy (AAS)

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

Storage and handling

• Protect cylinders, particularly the valves, from physical damage whether full or empty.
• Always store and transport upright.
• Always store in a cool well ventilated area (max. 45°C)
• Store away from combustible materials (refer to appropriate regulations for segregation from other dangerous and combustible materials).
• If valve is damaged, do not operate. If valve does not operate by hand, notify supplier and return cylinder with “faulty” 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

• No smoking or makes lights within 70 metres.
• Shut off engines, electrical equipment and all other sources of ignition.
• If possible, stop leak and remove cylinder to safe area.
• Notify emergency services if required.
• When cylinder has emptied, return to supplier with identification of problem.
