The Fire Extinguisher

A fire extinguisher is a red container filled with special chemicals. When you spray it on a fire, the chemicals put the fire out. Fire extinguishers are found in homes, schools, and buildings everywhere.

The History of Fire Extinguishers

People have been trying to fight fires for thousands of years. The first fire extinguisher was patented in 1723 in England. It was a barrel filled with a liquid that you threw at a fire.

Modern portable fire extinguishers were invented in the 1800s. They became smaller and easier to use over time. Today, you can find fire extinguishers on every floor of most buildings.

How Fire Extinguishers Work

Fire needs three things to burn: heat, fuel, and oxygen. A fire extinguisher works by removing one of these things. Most extinguishers spray foam or powder that covers the fire and blocks oxygen.

There are different types of extinguishers for different kinds of fires. The most common type in homes works on wood, paper, and electrical fires. You should only use a fire extinguisher on small fires and always call the fire department first.
