Gaseous Hydrogen Fires
Best practices for dealing with a gaseous hydrogen fire include:
- Do not extinguish the fire until the hydrogen supply has been shut off, as unburned gaseous hydrogen can result in an explosion. Spray water on adjacent equipment to cool it.
- Do not try to put out a hydrogen cylinder fire unless the cylinder is out in the open or in a well-ventilated area free of combustibles and ignition sources.
- Do not attempt to remove a burning cylinder. Keep it and surrounding cylinders cool by spraying with water.
- If multiple cylinders are burning, fight the fire from as great a distance as possible to protect against the possibility of flying debris.
