What are some of the safety considerations for use of hydrogen cylinders within a laboratory?

Cylinders used within a laboratory can be used safely by meeting the requirements prescribed in NFPA 2,
Hydrogen Technologies Code, and NFPA 45, Standard on Fire Protection for Laboratories Using Chemicals.
Special consideration should be given to both safe handling and storage of cylinders. Regarding lecture
size cylinders, their small size can make them susceptible to damage and mishandling. A release from an
open valve or relief device can be hazardous, particularly if the potential hazard is underestimated.
