All cylinders are dangerous. The following should never occur:
- The use of gas cylinders as rollers to transport heavy sections.
- Never use direct flame for any heating to raise the pressure of the cylinder.
- Never subject any cylinder to a temperature over 45ºC.
- Never recompress one cylinder from another.
- Never attempt to transfer gases from one cylinder to another.
- Never permit oil, grease or paint or similar substance to come into contact with oxygen cylinder valves.
- Never attempt to repair or modify cylinder valves or devices.
- Never allow electric arc welding tools to come near cylinders.
- Do not allow welding sparks and slag to make contact with cylinders.
- Never use anything but the recommended cylinder valve keys and never attempt to increase the leverage of keys.
- If you suspect that a cylinder valve is damaged, do not attempt to obtain gas from it.
USE OF LPG
The use of the LPG gas, once delivered for use in its gaseous as opposed to liquid form will need to be risk assessed but on the assumption that the delivery mains are to LPG ITA Standards the topic is best risk assessed according to the item of plant that the gaseous LPG is serving. This could be anything from profile cutting machines through to hot mill furnaces or simply space heating.
As with most fixed services it is probably the maintenance element where there will be greatest risk.
