Acetylene cylinders

Typical equipment used in oxy/acetylene gas welding and similar processes

Main Using Field

Acetylene for welding, cutting and similar processes.

How to prevent flashback:

Only use regulators, flashback arrestors, hoses and blowpipes designed for

acetylene and oxygen, respectively, and marked and manufactured to the correct

BS EN ISO Standards (see ‘Further information’).

For most welding and cutting processes, the acetylene pressure should not exceed

0.62 bar (9psi)

Before use Check:

✓ the identification on the cylinder;

✓ that it looks safe for use;

✓ that it is clean with no obvious damage.

After use

✓ Check there is no obvious damage.

✓ Turn off all valves (at cylinder, blowpipes etc).

✓ Vent excess gas from the hoses.

Training

✗ Do not use oxy/acetylene equipment unless you have been trained.
