Would you only use flashback arrestors with welding gear and oxy/gas cutting equipment or would you include other gas equipment as well; e.g. heating torches Is anyone aware of a gas regulator that has a flashback arrestor incorporated into it? I noted that HSE has withdrawn its guidance on the topic Edited by user 25 April 2024 16:27:37(UTC)

What exactly do you mean by heating torches? are you still talking about Oxy/Gas (Propane or Acetylene with Oxygen). It looks like you are if you have bottles with regulators, so I would say yes you do. The purpose of the is to stop flame going back to the bottle / regulator so why wouldn’t you regardless of what is on the end and alight. I have never seen of a regulator with arrester incorporated. Not sure it would be a good idea as when you get it inspected annually you would have to replace a more expensive product if one part was found to be faulty. Chris

AS far as I know if the gas is pressurised the arrestors are required.

Thanks for the responses. My view is that if there is presurised gas involved then a arrestor is required. I cannpt find and have not heard of a regulator thst incorporates the arrestror into it.
Again thanks for answers most helpful
