how does a fire extinguisher work
"Just how does a fire extinguisher work?" is a perfectly good interrogative sentence.
A hydrocarbon fire extinguisher is a type of fire extinguisher specifically designed to combat fires fueled by flammable liquids such as gasoline, oils, and grease. These extinguishers contain agents like dry powder or foam that work by smothering the fire and cutting off the oxygen supply to extinguish the flames.
A CO2 fire extinguisher will work on flammable liquid and electrical fires only. If used on any other type of fire they will just give it more oxygen and it will spread.
d type but they work only on specific metals
A tight-fitting lid, a fire blanket, a box of sodium bicarbonate or salt may work, but a type ABC fire extinguisher would be best. Turn off the electric source as well. Under NO circumstances use a water-type (often class A) on a hot oil fire or on an energized electrical device.
Generally, no, but a fire would.
Aim the fire extinguisher at the base of the flames, and sweep back and forthMore specifically:Trigger the fire alarm if not already done.Have others leave the area.Make sure you can get out safely and not be trapped.Select a fire extinguisher type according to what is burning.Pull the pinAim the nozzle at the fuelSqueeze the handleSweep from the edges toward the centerRepeat, as necessary, with another extinguisher, if you have one.
Depends of the type of fire extinguisher. Common CO2-extinguishers are filled with with compressed CO2. Once released it cooles down the fire below it's burning- or ignition-temperature and replaces the Air. The lack of oxigens will then suffocate the fire. No matter what type of extinguisher, it's always about cooling of suffocating the flame.
Not elemental hydrogen, no. That would not work in a fire extinguisher as hydrogen is highly flammable. Some fire extinguishers do use water, however, which is a hydrogen compound.
You can fill a fire extinguisher with any substance you like. Whether it will work as a fire extinguisher afterwards is a different matter. The old pump-style water fire extinguishers in college dormitories have occasionally been found to contain beer (which at least still works for the intended purpose) or gasoline (which is not so effective), which is one reason you don't see that type so much anymore.
