I've seen the plugs, both male (with a regular wrench or even pliers) and female (with the Allen key). We also have a shut-off switch which shuts off the flow of gas to the whole lab.

Since the serrated barb fitting is a 3/8" NPT connection to the valve, it could be replaced with a 3/8" NPT plug, such as this one:

Relatively tamper resistant and discreet. Just have to keep track of the allen wrench!

I have a client looking to lock out some existing deck-mounted laboratory natural gas fixtures such as these ones my company sells: http://www.safetyemporium.com/?L4200-131WSA

He said the spec calls for some sort of device that locks on to the hose barb. But the manufacturer of the valve doesn't have anything like that. We have some other type of lockout devices that might work on the handle portion, but before I recommend he start trying those out I thought I would consult the collective wisdom of the list first.

So, has anyone ever locked out their gas valves and how did you do it? Obviously, one can lock out the gas line master shut-off, but they are apparently looking to have individual ones.

Thanks.
