What is the correct procedure for using a fire extinguisher to put out a fire?

When operating a fire extinguisher, tell residents to remember the word PASS:

1. Pull the pin. Hold the extinguisher with the nozzle pointing away from you and release the locking mechanism.
2. Aim low. Point the extinguisher at the base of the fire.
3. Squeeze the lever slowly and evenly.
4. Sweep the nozzle from side-to-side.

When using a fire extinguisher which aim and motion should you use?

Pull the Pin at the top of the extinguisher. The pin releases a locking mechanism and will allow you to discharge the extinguisher. Aim at the base of the fire, not the flames. This is important – in order to put out the fire, you must extinguish the fuel.

How far away should you stand when using a fire extinguisher to put out a fire?

6 -8 feet

Which type of fire extinguisher is used to put out an electrical fire?

Class C fires

What to use to put out an electrical fire?

CORRECT WAYS TO PUT OUT AN ELECTRICAL FIRE

1. Use a fire extinguisher. You should use a multipurpose fire extinguisher with C in its label.
2. Use baking soda. Is there anything baking soda can’t fix?
3. Use a heavy blanket. Without oxygen, the fire can’t burn.

What element does not need to be present for fire to exist?

Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

Which of the following is not required for a fire to start and continue to burn?

Removing the fuel thereby decreases the heat. Without sufficient oxygen, a fire cannot begin, and it cannot continue. With a decreased oxygen concentration, the combustion process slows. Oxygen can be denied to a fire using a carbon dioxide fire extinguisher, a fire blanket or water.

Which combinations could start a fire?

The Fire Triangle. Three things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel. There must be Fuel to burn.

Is fire a form of dry heat yes or no?

Get the Facts Fire is the result of fuel, in the presence of oxygen, heated to the point that it combusts. Grass and wood are common fuels, because they burn easily when dry. Grills use charcoal or natural gas to create a fire. Fuel needs to be heated for combustion to happen.

What makes a fire worse?

Cooking oils and grease are not flammable. But when they reach their flashpoint, they will ignite quickly and burn intensely. If a fire comes in contact with cooking grease, whether in a bottle, refuse container, or spill, it will dramatically strengthen in mere moments.

What temperature is the coldest flame?

The lowest recorded cool flame temperatures are between 200 and 300°C; the Wikipedia page references n-butyl acetate as 225°C. You can read a lot more about cool flames on that page.

Is it ever too cold for fire?

It is not possible to freeze fire. A cool flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture. Contrary to conventional flame, the reaction is not vigorous and releases very little heat, light, and carbon dioxide.
