Fire prevention procedures should be established.
The most effective way to extinguish a hydrogen fire is to shut off the flow of hydrogen. Therefore, an emergency shutoff valve on the hydrogen supply piping should be installed in any laboratory that uses hydrogen.
Depending on laboratory arrangements and the quantities of hydrogen and other flammable gases in the lab, consideration should be given to the installation of an automatic sprinkler system (per NFPA 45 and NFPA 13) or another automatic fire extinguishing system (per NFPA 45).
The design and installation of fire detection and alarm systems (per NFPA 45) should be considered.
Laboratory designers should consult with the AHJ regarding specific requirements of the local fire and building codes.
The following should be given special fire prevention consideration:
- Handling and storage of gaseous and liquid hydrogen.
- A work permit system for using open flames or spark-producing equipment.
- Arrangements and use of portable electric cords.
- Smoking area controls.
