Fire Protection and Suppression

Normally hydrogen fires are not extinguished until the supply of hydrogen has been shut off due to the danger of re-ignition and explosion. Personnel who work around hydrogen should be trained in the characteristics of hydrogen fires and proper procedures for dealing with them.

• A hydrogen fire is often difficult to detect without a thermal imaging camera or flame detector.
• Let a gaseous hydrogen fire burn, but spray water on adjacent equipment to cool it.
• Be careful not to spray pressure-relief devices, since ice formation could make them inoperable.
