Is bonding and grounding ok for flammable gases or does it only apply to flammable liquids?

Is quantity and location a factor?

Please give advice.

I agree.  While I work in a lab that supports chemical manufacturing, I am embarrassed to admit that everything here is set up as it has been for essentially the last 30 years.  It was all set up originally by a somewhat maverick, free-thinking M..S. (Chemistry) and has served safely all these years.  But he died a couple of years ago, making me the senior (by years of service) person and now I have grave doubts and worries.  While our gases are stored and used in a more robust safety setup, I am now really concerned about the lack of monitoring for leaks of the gases used (H2, N2, He, nitric oxides, methane, ammonia, O2, etc).  We have NOTHING in our storage area or lab to monitor for leaks!

I would really appreciate it if DivCHAS or AIHA did a webinar on hydrogen safety as it pertains to research laboratories. There have been three hydrogen explosions at universities since 2010 (U. Missouri, Stoney Brook U. and U. Hawai’i). Scientists and EHS staff need better training on hydrogen safety, risks to look out for, and how to do a hazard assessment for research involving hydrogen. When we ask researchers about their setup, they say, “I’ve been doing this for years. This is the same setup described in the literature/that my mentor uses.” Please.
