Only authorized individuals should install or maintain high-pressure hydrogen systems.
Access to the hydrogen dispenser should be limited to trained operators. Administrative controls are appropriate for many installations; others prefer key or code access restrictions.
Hydrogen-specific emergency response actions should be incorporated into the existing facility emergency response plan.
Maintenance on high-pressure hydrogen systems should follow hazardous energy isolation practices (i.e., lock-out, tag-out).
Smoking or open flames should not be allowed in the refueling area.
The following checks should be made prior to commencing a filling operation:
A leak check of the entire dispenser
An instrument check
Another leak check after connection to an industrial truck
