Alert! Before using a fire extinguisher, ensure that someone: notifies the fire department, alerts others about the fire, begins evacuating others from the premises.
Fire extinguishers are for controlling small fires before they have a chance to spread. Before using one, make sure that: you have a clear escape, you are familiar with the operating instructions of the fire extinguisher, and that the fire extinguisher you have it suitable for the fire you are facing.
Before using the extinguisher on the fire, look at the fire class symbols on the front label to make sure the extinguisher you have is suitable for the type of fire you’re facing. Most common cases of fires are: A, B, C, K. Class A fires involve common combustibles like wood, paper and tires. Class B involve flammable liquids like gasoline and petroleum oil. Class C involve energized equipment or things that are plugged in like appliances, computers, tvs and electric machinery. Class K fires involved cooking oils and grease, like vegetable fats.
