A fire blanket is put over a fire what has been removed?
ELISSACOOLSTAR
Firefighters use many methods to put out fires. The extinguishing method depends on four factors, which are called the fire tetrahedron.
Imagine a pyramid with four sides. The sides are:
- Fuel (Reducing Agent)
- Oxygen (Oxidizing Agent)
- Heat
- Self sustained chemical reaction.
If you remove one of those four factors, the fire will go out.
For instance when fighting a class A fire (ordinary combustibles like wood and paper), the best method is often to remove heat. Firefighters do that by applying water to the fire. Also, once enough water is applied, it can also remove oxygen from the process by smothering the fuel.

∙ 13y agoFire blankets can be used on any small source of fire. They are typical used when traditional fire extinguisher are not appropriate for example; an oil fire were the only available extinguisher is water based. I you are not sure whether or not to use an extinguisher or a blanket don't tell somebody or activate an alarm.

Some firefighters have the good fortune to have water available, either because they're close to urban areas, or they have pumps that can draft (suck) water from natural sources and direct the water through hoses to the hot spots.
Aerial water and fire retardant is very expensive and is only used when necessary to protect human habitations, valuable timber or other economic or cultural interests.

How do you use fire blanket?
A fire blanket either completely surrounds a burning object or is placed over a burning object and sealed closely to a solid surface around the fire. Whether the blanket is placed on top, or surrounding it, the job of the blanket is to cut off the oxygen supply to the fire, and put it out. In using a fire blanket, it is important to protect the hands
Why during in fire you rap awoollen blanket over the burning object?
Fire requires three things: heat, fuel, and oxygen. If you take one of them away, then the fire will stop. By wrapping a heavy blanket around a burning object, it blocks oxygen in the air from getting to the fire and the fire goes out. This is why a fire blanket is standard safety equipment in school science labs.
A fire blanket is put over a fire what has been removed from the fire triangle?
The fire triangle is fuel, oxidant (or oxygen), and ignition source. When you use a fire blanket to put out a fire, you are cutting off the supply of fresh oxygen (the oxygen still under the blanket gets consumed as the fuel burns).There are however various components that can burn with no oxygen present.A fire is in a way no more than a powerful chemical reaction making a lot of heat.Heat itself will increase the rate of the chemical reaction and this is often why we consider a fire to be out of control. Common for all fires is that they need something to react with. If one remove the reactant from the fuel, then the fire stops. What the reactant is depends strongly on the fuel at hand.A normal approach in order to put out a fire is to use vast amounts of water.This works quite effectively in two ways. Firstly by lowering the temperature. secondly by forming steam of which removes oxygen (reactant).There are however fires that very well burn vicariously even when submerged totally in water. Such a fire can occur when we burn the metal Magnesium.Under normal circumstances such a fire will only be put out with sufficient amounts of sand or salt. This will remove available oxygen or reactants and the fire will stop.Most fires can be put out if one have a fire extinguisher filled with Nitrogen. We normally say that nothing can burn in an atmosphere of pure Nitrogen. This is however not so when it comes to a fire with Magnesium. Magnesium burns equally as well with Nitrogen instead of Oxygen.
When you warm your hands over a fire the heat of the fire is being?
Radiated
How has the work of Robert Bunsen changed your lives?
he has made a safe way to see how chemicals react when they have been over the fire for a certain amount of time
Where can I find information on what a fire blanket is?
A fire blanket is used to extinguish small starting fires. It's made of fire retardant material such as fibreglass, kevlar or just wool treated with a fire retardant fluid. You place a fire blanket over a fire to smother it.

What is a lab safety device consisting of a fire-retardant material that can be thrown over a small fire to smother it?
a fire blanket
How does a blanket help to extinguish a fire?
A fire requires oxygen in order to continue to burn. Placing a blanket over the fire robs it of the necessary oxygen, and thus helps to extinguish the flame.
How would you handle a highly flammable product that caught on fire?
throw a blanket over the top of the fire
What do you use a fire blanket for?
putting over fires as it gets rid of the oxygen the fire needs to burn
Why to use a fire blanket on a fire in a cooking oil fire?
Because you dont put water on a oil fire or a explosion will happen. This includes a grease fire... Dont put it out with water... If you put a fire blanket over it... It will put it out the safe way E.G. Smuther it.
What do you do if your cat is on fire?

What was the temperature of the atomic bomb explosion over hiroshima?
2,000 degrees in the fire blanket.
What is taken away if you smother a fire with a fire blanket?
The Oxygen that fuels a fire, is not able to get in, and the fire is put out. Just like with a candle snuffer. You put the snuffer over the flame, and the fire gets put out.
Why does covering a burning object with a blanket help to extinguish a fire?
throwing a blanket over a small contained fire stops oxygen to the fire .to stop a fire you need to take out one of the three elements that are needed for a fire to burn witch are heat /oxygen/fuel
