Fire Trucks and Other Emergency Vehicles
Most fire trucks and other emergency vehicles are fitted with audible warnings, also known as sirens, to warn people of impending danger before they arrive on scene. Mechanical bells mounted on the trucks were the first audible warnings, but today most vehicles are equipped with electronic sirens, which emit a variety of different sounds. Your fire service driving training may involve practicing these sounds in various situations, such as in urban areas or when making a maneuver.
A fire truck’s water supply is its most vital component, making it useful for fighting fires and sucking water from various locations. The water pump is operated by an engine that spins blades, forcing water in. When the valve is opened, water is forced outward. Firefighters control the pump with levers and hoses, and there is a water tank panel on the side of the truck that tells them when the water tank is almost empty. They can then call for backup or get more water in case of a shortage.
Some fire trucks also have fixed deluge guns, which direct a heavy stream of water into the fire. These guns are attached to external, permanent sources of water. Firefighters can also use their own water tenders, which are often positioned close to the fire site. These trucks have the capacity to tackle fires faster than their counterparts. They may also be equipped with thermal imaging cameras. So, if you need to call for emergency assistance, fire trucks are always prepared.
Type 5 through 7 fire engines are designed for initial response. Their GVWR ranges from 26,000 pounds for the Type 5 to 14,000 pounds for Type 7. Each is built to carry a minimum of two personnel and has a hose diameter of one to one and a half inches. They also carry larger tanks than Type 3 engines. If you need a custom apparatus, Pierce Manufacturing can help you with that. The fire service uses these vehicles extensively.
A fire truck can be either a conventional or aerial apparatus. Aerial apparatus trucks are equipped with a boom and are used to put out tall building fires. Not all fire engines are red, though. Their colors are determined by their specific purpose and location. You might be surprised to find a fire truck in your community or in another city. If you see one in the area, don’t hesitate to stop by and take a closer look.
Type 2 trucks are smaller versions of the Type 1 engines, and are ideal for wet or heavy-duty rescue. They have fewer water tanks and pumps, but can still hold a large amount of equipment. They often arrive first and can put out a fire until more support arrives. They usually carry three or four firefighters, and their equipment includes axes, ladders, and other basic firefighting gear. In addition to firefighting gear, they may also include hazmat equipment and additional structural gear.
