What is the most important characteristic of the extinguishing agent is fighting a Class C fire?

It acts as a barrier to exclude oxygen from a fire. The extinguishing agent in a Class C fire extinguisher must be electrically nonconductive. Both carbon dioxide and dry chemicals can be used for electrical fires. An advantage of carbon dioxide is that it leaves no residue after the fire is extinguished.

Which is the best extinguisher for C type fire?

What is the best fire extinguisher for a Class C fire? For fires that involve sensitive equipment such as computers, servers, data centers, or other electrical equipment, Carbon Dioxide and Halotron Fire extinguishers are the best options to extinguish the fire without damaging the sensitive equipment.

What is a Class C fire extinguisher?

Class C fires involve energized electrical equipment. Extinguishers with a C rating are designed for use with fires involving energized electrical equipment.

What is a Class C fire extinguisher made of?

These Class C fire extinguishers may contain monoammonium phosphate, potassium bicarbonate, or potassium chloride, all of which are suitable for putting out Class C fires.

What Class C fires involve?

Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires – the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive.

Which fire fighting agent is most effective at removing heat?

The preferred method for extinguishing class “A” fires is to remove the heat. Water is the most common agent, but others such as dry chemical, halon, halogenated agents and foam can be used effectively.

Which of the following fire extinguishing agent is suitable for a live 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.

What are the classes of fire and its extinguishing agents?

Class A – Ordinary combustibles (solid material fires) – wood, paper, plastic etc, Class B – Flammable liquids or gases – fuels, alcohol, aerosols, Class C – Electric fires, Class D – Combustible metal fires – magnesium, potassium etc.

What is the purpose of a fire extinguisher?

Fire extinguishers apply an agent that will cool burning heat, smother fuel or remove oxygen so the fire cannot continue to burn. A portable fire extinguisher can quickly control a small fire if applied by an individual properly trained. Fire extinguishers are located throughout every building on campus.

How does a CO2 fire extinguisher work?

Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.

Why is carbon dioxide so effective for use in extinguishing Class C fire?

Class C fires, which involve energized electrical equipment, can also be extinguished with CO2. CO2 displaces the oxygen to extinguish the fire. … This “cloud” of CO2 reduces the oxygen in the air around the fire and smothers it.

Why is CO2 better than dry chemical for fighting a Class C fire?

Carbon dioxide fire extinguishers extinguish fire by taking away the oxygen element of the fire triangle, and by removing the heat with a very cold discharge. Carbon dioxide extinguishers can be used on Class B and C fires. They are usually ineffective on Class A fires.
