What are the six classes of fire?
There are 6 different classes of fire, and each should be attacked in a different way.Class A (Solids) Class A fires are fires involving solids.
Class B (Liquids) Class B fires are fires involving liquids.
Class C (Gases) …
Class D (Metals) …
Class F (Cooking Fats & Oils).
What is type of fire?
There are four classes of fires: Class A: Ordinary solid combustibles such as paper, wood, cloth and some plastics. Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.
What is D class 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 the most flammable gas?
hydrogenAlthough hydrogen is the most flammable element, the most flammable chemical probably is chlorine trifluoride, ClF3.
What is a highly flammable gas?
Acetylene, hydrogen, propane, propylene and methane are all flammable gases referred to as ‘fuel gases’. When these gases are mixed with an oxidant and provided with an ignition source, they will burn.
What are the 3 classes 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 are the 5 classes of fire?
Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach.
What does flammable gas 2 sign mean?
Description. Indicates the storage or containment of Class 2 Flammable Gases within a facility, vehicle or container etc. Class 2, Division 2.1 Flammable Gas is defined as Gases which, at 20 °C and a standard temperature of 101.3 kPa, are ignitable when in a mixture of 13% or less by volume in air.
What does ABC mean on fire extinguisher?
Dry Chemical Extinguishers “DC” short for “dry chem” • “ABC” indicating that they are designed to extinguish class A,B,and C fires, or • “BC” indicating that they are designed to extinguish class B and C fires. “ABC” fire extinguishers are filled with a fine yellow powder.
What are the 4 types of fire extinguishers?
There are 5 main fire extinguisher types – Water, Foam, Dry Powder, CO2 and Wet Chemical.
What is a Category 1 flammable gas?
Category 1 designates gases which at 20°C (68°F) and a standard pressure of 101.3 kPa (14.7 psi) are ignitable when in a mixture of 13% or less by volume OR have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit.
What class is non flammable gas?
Class 2Class 2 Non-Flammable Gas/Flammable Gas Placard – Worded.
Is gasoline a Category 1 flammable liquid?
Additionally, unstable flammable liquids are treated as Class IA liquids. … Typical Class IB liquids include acetone, benzene, ethyl alcohol, gasoline, and isopropyl alcohol. Class IC liquids are have flash points at or above 73 °F (22.8 °C), but below 100 °F (37.8 °C).
What is the difference between a 1 alarm and a 2 alarm fire?
A one-alarm call is the basic response to a fire alarm, and usually includes two pumper trucks, a rescue unit, a ladder truck, and a chief to supervise things. If the first unit thinks it’s necessary, they’ll call in a second alarm, which will double the fire department’s response.
Is oxygen a Class 2 gas?
Commonly transported class 2 dangerous goods include oxygen, natural gas, carbon dioxide, lighters, and aerosols.
Which gas is non combustible?
Inert gases are non-combustible, non-flammable, and non-reactive to many materials. Examples include argon, helium, nitrogen, and neon.
What category of fire is flammable gas?
Class C fires are identified by the presence of a burning gas. The most common flammable gases involved in fires are propane, butane and methane, and they form the ‘fuel’ aspect of the fire triangle, which is required for the fire to start, spread and continue to burn.
What does flammable gas mean?
A flammable gas is a gas that burns in the presence of an oxidant when provided with a source of ignition. Flammable gasses can include methane, acetylene, ammonia, hydrogen, propane, and propylene. The risk of a fire starting increases in relation to the amount of gas present.
