“What hydrogen hazards associated with this project have the potential to result in the
worst consequences?”
• Try to reduce or eliminate the higher risks by using the proper ventilation to remove
hydrogen gas before an ignitable concentration can accumulate. You should also consider
purging the hydrogen to further reduce hazards and ensure anyone who will be working
with hydrogen has basic hydrogen safety training.
• As with laboratory safety in general, be sure to wear safety glasses, laboratory coats, gloves,
etc. Typically there are no specific requirements for gaseous hydrogen, other than eye
protection when working with a compressed gas. If working with liquid (cryogenic)
hydrogen, insulated gloves and protective shoes should be worn in addition to eye
protection.
• You should post “No Smoking” and “No Open Flames” signs to identify hydrogen
sources and cylinders. Maintain, inspect and leak-test all hydrogen sources regularly.
• All hydrogen shutoff valves should be clearly marked and permanent hydrogen piping
should be labeled as such at the supply or discharge point and at regular intervals along its
length. Where hydrogen gas piping passes through a wall, the piping should be labeled on
both sides of the wall.
• There should also be contingency plans in place should an incident occur.
• The site emergency response team, as well as the local fire department, should know the
location of all hydrogen storage tanks.
Using Hydrogen with TSQ 9000
To use hydrogen with the TSQ 9000, you must always shut off the GC carrier gas before
venting or turning off the TSQ 9000. There are three hydrogen safety screws on the
TSQ 9000 that
must
be in place. These are attached to your instrument at the factory.
