Fire trucks are an important part of the public safety machinery. While the primary purpose of a fire engine is to fight a fire, they also do other important tasks like saving lives, rescuing people from the scene of a fire, ventilating a building, and providing emergency first aid. Some fire trucks are equipped with a mobile medical unit to help people who have been injured in the fire. Fire trucks are also equipped with oxygen tanks that provide breathing assistance during a fire.
A fire truck has three parts: a pump, a water tank, and a hose. There are a wide variety of hoses that firefighters can use to fight a fire. Firefighters can deploy hoses from the tank and into a building. Some engines are equipped with hose reels, which allow firefighters to deploy hoses quickly and easily. Firefighters can also use fire hydrants and other sources of water to do their jobs.
Fire trucks are equipped with foam systems made by E-One, Pierce, and other manufacturers. These systems use CAFS (Compressed Air Foam System) and have various types of foam. Class A foam is designed to saturate flammable materials, while Class B foam is used for flammable liquids. Fire trucks typically have tanks of 500-3,000 gallons of water. Hoses connect to various points on the truck and expel water at different pressures and rates.
Fire trucks also have a variety of tools. The water tank typically contains 500 gallons of water, and some of them even have a camera to help firefighters detect smoke. NFPA standards require that fire trucks also have a pump that can pump 150 gallons of water per minute. They are also equipped with ladders and other tools that help firefighters do their jobs better. When it comes to fire fighting, it’s best to have the right equipment.
While a fire truck can handle a wide range of emergency situations, its most important function is rescuing people. In the past, firefighters stood on the sides of a fire truck or stood at the rear. This was uncomfortable and often dangerous. Some firefighters were thrown to their deaths during sharp turns. Now, most fire trucks have enclosed seating areas for the crew. They also include a fire safety system to reduce the risk of backdraft.
The history of fire trucks dates back to Colonial times. The Colonial laws required homeowners to place buckets of water on their front stoop, but these buckets were only for the initial bucket brigade. In 1719, Philadelphia finally acquired its own hand-pumped fire engine, which was designed by Joseph Jenckes Sr. It arrived in the US before the two engines from London. Eventually, the entire nation became equipped with firefighting equipment.
