Question: What type of fire can be put out safely with water?

What type of fire can be put out safely with water quizlet?

Water is an excellent extinguishing agent suitable for Class A fires (ordinary combustibles) only. It cools the fuel below its kindling temperature. Never use on electrical equipment or for fires in cooking media. The water could flash to steam as a result of high temperatures and cause serious burns (96).

What type of fire can you safely use a water extinguisher on?

WATER. Water fire extinguishers have a class A rating and are suitable for fighting fires involving solid combustibles such as wood, paper and textiles. Electrical equipment should be avoided when using a water extinguisher (unless water with additive are used).

Can you put out a gasoline fire with water?

Liquid gas fires (like gasoline) can be put out by smothering with a blanket. Water is ineffective in putting out a gas fire and can increase the chance of injury, as the heat from the fire will boil the water almost immediately, putting you at risk for steam burns.

Can you set fire to water?

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.

What is a danger to consider when attacking a Class C fire?

Class C fires are fires involving gases. This could be natural gas, LPG or other types of gases forming a flammable or explosive atmosphere. Work with gas is dangerous, and increases fire risk.

Which fire extinguisher class is best for an electrical fire?

Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment. Both monoammonium phosphate and sodium bicarbonate are commonly used to fight this type of fire because of their nonconductive properties. Fire extinguishers are classified by fire type.

What are the 4 types of fire?

Classes of fire

  • Class A – fires involving solid materials such as wood, paper or textiles.
  • Class B – fires involving flammable liquids such as petrol, diesel or oils.
  • Class C – fires involving gases.
  • Class D – fires involving metals.
  • Class E – fires involving live electrical apparatus. (

What is the best defense against fires?

As always, the best defense against a fire is to be prepared. Take a moment to look at your fire extinguisher.

What are the 5 classes of fire?

Fire is divided into five classes (A, B, C, D, and K) that are primarily based on the fuel that is burning. This classification system helps to assess hazards and determine the most effective type of extinguishing agent.

Can salt put out a fire?

Salt will smother the fire almost as well as covering it with a lid, while baking soda chemically extinguishes it. But you’ll need a lot of each–toss on handfuls with abandon until the flame subsides. Avoid using flour or baking powder, which can explode in the flames instead of snuffing them out.

Does water kill fire?

When water hits something of very high temperature, it boils, and by boiling it absorbs a lot of heat, rapidly cooling the fuel. When the fuel is no longer hot enough to burn, the fire goes out. In situations like that, you can effectively smother a fire with water, making it impossible to burn.

What puts out fire the fastest?

Grease Fire

Sprinkle baking soda or salt on the grease. This will quickly absorb it and will put out the fire out at its source. You can also use a fire extinguisher on a grease fire, but DO NOT use water or flour. Flour can make it worse and water does not mix with oil, hence it would only cause the fire to spread.

Can water get hot enough to start a fire?

Water doesn’t burn, not at any temperature. It’s the result of burning. There’s not really anything else it can burn into. Heat the water up enough (several thousand degrees) and it will glow, just like any gas, but it’s not burning.

Can water make a fire worse?

3. Do NOT pour water on the fire! Since oil and water do not mix, pouring water can cause the oil to splash and spread the fire even worse. In fact, the vaporizing water can also carry grease particles in it, which can also spread the fire.

What chemical starts on fire with water?

The alkali metals such as sodium, potassium and lithium react with water to produce heat and flammable hydrogen gas, which can ignite or combine explosively with atmospheric oxygen. Water-sensitive chemicals are materials which react violently with water to produce heat and flammable or toxic gas.
