Fire Triangle Fire Research Paper

This is The Fire Triangle- there are four elements that make a fire. There must be oxygen to sustain combustion, heat to raise the material to its ignition temperature, fuel to support the combustion, and a chemical reaction between the other three elements. If any one of those four elements are removed, the fire is extinguished. To extinguish a fire, fire extinguishers have been made.

The fire extinguisher is an active fire protection device used to put out fires of limited size. In the United States, fire extinguishers are in every building, other than houses. That means these things are basically everywhere, but a lot of us don’t know their proper functionalities. Not all fires are the same. Different fuels create different types of fires and require its own type of fire

extinguishing class:
Class A fires includes materials such as wood, cloth, and paper are burning.
Class B fires are for flammable liquids, oils, and grease.
Class C fires are those involving live electrical equipment such as motors, transformers, and appliances.
Class D fires are fires in combustible metals.
Class K fires are fires in cooking oils and greases.

Some specific fire extinguishing agents can be used on more than one class, but some have warning labels where it would be dangerous to use a specific extinguishing agent. When used properly, fire extinguishers can save lives by putting out a small fire or containing it until the fire department arrives.

Types of Fire Extinguishers
Water and Foam
Water and Foam fire extinguishers extinguish the fire by taking away the heat element of a fire.

Foam agents also separate the oxygen element from the other elements.

Used for Class A fires only. This should NOT be used on Class B or C fires.

Carbon Dioxide

Carbon Dioxide fire extinguishers extinguish fire by taking away the oxygen and heat element of a fire.

Used for Class B & C fires. Usually ineffective on the other Class fires.

Dry Chemical

Dry Chemical fire extinguishers extinguish the fire by interrupting the chemical reaction of the fire.

The most commonly used fire extinguisher is the multipurpose dry chemical that is effective on Class A, B, and C fires. Ordinary dry chemical is for Class B & C fires only.

Wet Chemical

Wet Chemical is a new agent that extinguishes the fire by removing the heat of the fire and prevents re-ignition. These extinguishers were specifically developed for high efficiency deep fat fryers cooking operations.

Used for Class K.

Clean Agent

Clean Agent extinguishers include the halon agents along as halocarbon agents. They extinguish the fire by cutting off the chemical reaction of a

fire.
Used for Class B & C fires
Dry Powder
Dry Powder extinguishers are like dry chemical, except they extinguish the fire by separating the fuel from the oxygen element or by removing the heat.
Used for Class D only.

Water Mist
Water Mist takes away the heat element of the fire. They are an alternative to the clean agent extinguishers.
Used mostly for Class A fires, but are also safe to use on Class C fires.
Cartridge Operated Dry Chemical
Cartridge Operated Dry Chemical fire extinguishers extinguish fire by cutting off the chemical reaction.
Used for Class A, B, and C fires. Ordinary dry chemicals are used for Class B & C fires only. It’s important to know what kind of extinguisher you should be using because the wrong one could re-ignite a fire

Fire Extinguisher Use
It is important to know a few things before using a fire extinguisher:
Fire extinguishers can weight a lot, so it would be a good idea to practice picking up and holding one up. Another thing to do which is important is take time to read the instructions and warnings labels on the fire extinguisher. Practice releasing the discharge hose and aiming it at the base of an imagined fire. Do not pull the pin or squeeze the lever. This will break the seal and cause it to lose pressure.
When it is time to use the extinguisher, just remember PASS!
P...Pull the Pin
A...Aim extinguisher nozzle at the base of the flames
S...Squeeze the lever to discharge the fire extinguishing agent.
S....Sweep the extinguisher from side to side
