These are only mandatory on welding cylinders. They are designed to protect against a flashback if the hoses fail

Hi All,

One of the instrumentation labs I work in recently had a report suggesting that both the hydrogen and acetylene tanks be equipped with flashback adapters. These are for tanks used for a GC and a Flame AA. The manufacturer, however, suggests that these regulators arent necessary. I was wondering if anyone on this listserv could comment on whether they use flashback adapters for tanks attached to GCs and FAA instruments.

Thanks,

Steve
