I don't disagree with the suggestions for O2 sensors but it is really important to make sure you get the right oxygen sensor.  We had an awful time with false alarms-which cause a lot of disruption initially as the building clears out and first responders stream in--and then after a bunch of these, people hit mute buttons and/or come up with very novel re-wiring to turn the alarm off.  Talk with someone from the vendor who really understands the different types and what you need for your particular lab set up.  We have several of these for our NMR rooms and since we don't have the same application as you do, I don't feel able to give a more specific recommendation, sorry.
Best,
Margaret

Margaret,

I would also use a room O2 sensor for the room.  It helps the team to know if oxygen levels are slipping to dangerous levels because of a H2 leak.

Greetings,

 

I have a researcher who is intending to start work on a hydrogen fuel cell. I want to make sure I have covered all the bases when I talk with him. The hydrogen sensor has already been purchased, but if you can provide any extra guidance, that would be great.

 

Thank you,
