What are the 6 classes of fire?
Fires are broken up into six different classes:Class A – solids, such as paper, textiles, wood, plastics and rubber.Class B – flammable liquids, such as petrol, oil and paint.Class C – flammable gases, such as propane, butane and methane.Class D – metals, such as aluminium, magnesium and titanium.More items…
What are the four classes of fires in the United States?
CLASSES OF FIRESCLASS A – Ordinary combustibles such as wood, cloth, and paper.CLASS B – Flammable liquids such as gasoline, oil, and oil-based paint.CLASS C – Energized electrical equipment, including wiring, fuse boxes, circuit breakers, machinery and appliances.CLASS D – Combustible metals such as magnesium or sodium.
Which is an example of a Class C fire?
A Class C fire is the burning of flammable gases, which can be very dangerous and highly explosive. These include gases such as butane and propane in gas canisters, which you’d expect to find in certain building trades. You will also find these with gas camping stoves and gas barbeques.
What is a Class D fire?
Class D fires involve combustible metals – especially alkali metals like lithium and potassium, alkaline earth metals such as magnesium, and group 4 elements such as titanium and zirconium. … Therefore, even a small metal fire can spread and become a larger fire in the surrounding ordinary combustible materials.
How do you extinguish a Class D fire?
How do you extinguish a Class D fire? The best and only recommended way to extinguish a Class D fire is to use a dry powder fire extinguisher. This works by smothering the fire, and therefore the oxygen within it, and also absorbing the heat contained within the fire, eventually leading to its extinction.
What materials cause a Class D fire?
Class D fires only involving combustible metals – magnesium, sodium (spills and in depth), potassium, sodium-potassium alloys uranium, and powdered aluminum. What is the proper way to use a Class D, sodium chloride extinguisher?
What is Class C fire?
Class C fires are fires involving energized electical equipment such as computers, servers, motors, transformers, and appliances. Remove the power and the Class C fire becomes one of the other classes of fire.
What are the 5 classes of fire extinguishers?
The 5 Classes of Fire Extinguishers Fire extinguishers aren’t one size fits all; in fact, there are five different fire extinguisher ratings: A, B, C, D, and K. Each rating denotes the type of fire the extinguisher can be effectively used against.
What are the 4 types of fire?
Classes of fireClass 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. (More items…
What is ABC type fire extinguisher?
This pale, yellow powder can put out all three classes of fire: … Class A is for trash, wood, and paper. Class B is for liquids and gases. Class C is for energized electrical sources.
What are the 4 types of fire extinguishers?
There are four classes of fire extinguishers – A, B, C and D – and each class can put out a different type of fire.Class A extinguishers will put out fires in ordinary combustibles such as wood and paper.Class B extinguishers are for use on flammable liquids like grease, gasoline and oil.More items…
What is the symbol for a Type C fire extinguisher?
Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive. The geometric symbol indicating Class C is a blue circle. Class D fire extinguishers are commonly found in a chemical laboratory.
Which is the most suitable fire extinguisher for class D type of fire?
Dry powder extinguishers Specialist powder extinguishers are designed to tackle type D fires involving combustible metals such as lithium, magnesium, or aluminium. They work by the powder forming a crust which smothers the fire and stops it from spreading.
