A fire blanket is put over a fire what has been removed from the fire triangle?
ELISSACOOLSTAR
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.

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
What equipment is located in the lab in case of fire?
Fire extinguisher and fire blanket.
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.
What are the safety equipment in the science lab?
fire blanket
How can you use smother in a sentence?
It is sometimes possible to smother a fire with a blanket.
After you have put out an electrical fire what has been removed from the fire triangle?
Now..... Don't use water!! Use sand ..... i think that heat is removed
Do the fire service remove fire blankets from a fire?
the fire blanket removes one side of the fire triangle
Which side of the fire triangle is removed by a firebreak?
A fire triangle consist of Fuel (Bushes), Heat (Fire) and Oxygen and the three combine creates a chemical chain reaction.In this case the fuel is removed so if there is nothing to burn you have no fire.
Which part of the fire triangle is removed by the firefighters?
heat or oxygen
What can stop fire?
A fire blanket or a non-flammable blanket can help stop a small fire from spreading because when you place then blanket over the fire it cuts off the oxygen to the fire. Cutting this part out of the fire triangle stops the fire from spreading and growing. Fire triangle = Heat, Fuel, Oxygen.
What are the three points of a fire triangle?
The three elements of the fire triangle that must be present are Heat, Oxygen, and Fuel. This has recently been changed though from the fire triangle to the fire tetrahedron. This includes Heat, Oxygen, and Fuel as well. But, it also contains a fourth, chemical reaction.
What happens to a fire if you cover it with a fire blanket?
Its put out. The fire consumes itself, the oxygen flow has been cut off.
How do you use a fire blanket?
1. Stay Calm.2. Take Fire Blanket Out of Package3.) Hold The Fire Blanket handles, and be sure that your hands are protected by the blanket.4.) Approach Fire and place blanket on top of the fire. Do not worry about smothering the fire with force, just allow the fire resistant materials to smother the fire.5.) Remove the blanket from the area - unlike a fire extinguisher, there is no messy clean up.6.) Sometimes the Fire Blanket may be used multiple times depending on the severity of the fire.
Can a fire blanket be reused?
Some types of fire blankets can be reused and you will need to read the manufacturers instructions on the product or contact the manufacturer. If you try and reuse a fire blanket that has some damage to it you may find that much of the fire resistance has been removed making it obsolete, in cases such as these it should be replaced with a new one. You will also have difficulty in repacking them and the cost is not prohibitive so in many cases the best option is to replace it.
