Water vapours also surround the combustible material, helps in cutting off the supply of air. So, the fire is extinguished. Therefore hydrogen is a combustible gas and oxygen is a supporter of combustion but water extinguishes fire. Hydrogen Creates Unique Challenges for …
Use In Antacids, Use In BakingUse in fighting fires. In the presence of acids, these ions create carbon dioxide gas (CO 2) and water. Baking soda, a weak base, is used in antacids, fire extinguishers, and baking powder. In almost all of its common uses, sodium bicarbonate is employed to produce carbon dioxide gas.

Hydrogen is a tiny molecule, and actually produces relatively little force during an explosion. Even under BLEVE conditions, the primary danger is from spalling of the container. Hydrogen fires are best extinguished by waiting for the supply of hydrogen to be shut because of the danger of re-ignition and explosion.
People Also Ask why is hydrogen used in fire extinguisher
Do CO2 extinguishers work for hydrogen fires?
I used to work where we made chlorine, hydrogen, and caustic soda. Chlorine and hydrogen were low pressure. We would often enough have hydrogen fires and we used CO2 extinguishers. They worked well. Next door the hydrogen was compressed to higher pressures. 4 stages with the final stage being if I remember correctly 200 psi or maybe 250 psi.
How would you extinguish a hydrogen fire?
Hydrogen fires are best extinguished by waiting for the supply of hydrogen to be shut because of the danger of re-ignition and explosion. They all would ….if you were fast enough to get it deployed before the explosion ended!
Is hydrogen flammable?
Hydrogen is a flammable gas at atmospheric conditions and diffuses rapidly in air and through materials not normally considered porous.
What are the challenges of using hydrogen as a fuel?
While the concept of using hydrogen in a variety of industrial processes is not new, using it as a fuel source creates unique challenges. The proper handling of the gas is critical and any emergency situation requires proper fire protection equipment.
