Can hydrogen be used to extinguish fire?

Can hydrogen be used to extinguish fire?

Water is made up of two elements, hydrogen and oxygen. Hydrogen is flammable, but oxygen is not. You can’t burn pure water, which is why we use it to put out fires instead of starting them. You can, however, break it down into hydrogen and oxygen by putting energy into it, in the form of an electric current.

Why water is used for fire extinguisher as it is made of hydrogen and oxygen while both are helping in production of fire?

This means that when water H2 O is applied to a developing fire in ordinary combustible materials, the water does not break down into the basic elements of Hydrogen (H) and Oxygen (O), both of which would encourage fire growth. Water absorbs 143.4 Btus per pound in this process.

Why h2o is used as fire extinguisher?

water does not catch fire beacuse it can’t burn anymore. Burning in our atmosphere is a reaction with oxygen and in water hydrogen and oxygen have already burned. you can’t burn twice. The reason water extinguisher Flame is because it is exceptionally good at absorbing heat.

Why is water used as an extinguishing agent?

The most common fire-extinguishing agent, water, meets this requirement. Because of its high specific heat and high latent heat of vaporization, a mist of water droplets should be an excellent fire-extinguishing agent. Removing heat from a flame reduces its temperature and leads to flame extinguishment.

Why co2 is not used for class A fire?

Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. CO2s may be ineffective at extinguishing Class A fires because they may not be able to displace enough oxygen to successfully put the fire out. Class A materials may also smolder and re-ignite.

What is the disadvantage of water fire extinguishers?

Disadvantages Of Water Extinguishers Water fire extinguishers are only suited for one Class of fire. Do not use on electrical fires due to shock hazards. Using water fire extinguishers for fat and also flammable liquids will aggravate the fire.

Can a water fire extinguisher burn the water?

Water itself can certainly not burn. Yes, if a water fire extinguisher is used inappropriately, on (say) something like a Magnesium fire. The Magnesium extracts the Oxygen from the water and the Hydrogen then burns.

What are the different types of water extinguishers?

There are two types of water type extinguisher according to their operational method: 01. Water(Gas cartridge) type extinguisher 02. Water(Stored Pressure) extinguisher 01. Water(gas cartridge) type extinguisher In this type of extinguisher water is used as an extinguishing material.

How does a fire extinguisher work to put out a fire?

Stand approximately 8 feet away from the fire and squeeze the handle to discharge the extinguisher. If you release the handle, the discharge will stop. Sweepthe nozzle back and forth at the base of the fire and slowly move forward to extinguish the remaining fire. After the fire appears to be out, watch it carefully since it may re-ignite!
