The nozzles and brass couplings that are attached to fire hoses are as important as the hoses themselves, and must be in proper working order. Similar to the idea that different fire extinguishers are used for fighting a variety of fires, there are also many different types of nozzles that have been created for a variety of situations. Nozzles are used for three purposes:
• to dispense a liquid over an area
• to increase liquid surface area and
• generate impact force on a solid surface.
As the term suggests, a spray nozzle helps to disperse liquid into a spray. In this case, a spray is a dynamic collection of liquid drops that are dispensed over an area. At Reliable Fire Equipment Company, our experts can help determine the type of nozzle you need.
A fire monitor is a controllable, high-capacity water jet that can be aimed in various directions and is often used for manual firefighting or automatic fire protection systems. Fire monitors are designed to be used with foam that can be injected in the upstream piping. You will often see them fitted to fire boats or tug boats, and mounted on top of some of the larger fire trucks.
Fire monitors are also used in fixed fire protection systems to protect high hazards, such as aviation hangars and helicopter landing pads. One of the benefits of a fire monitor that is mounted to an apparatus, is that it can be directed by a single firefighter, compared to a standard fire hose which normally requires several. Fire monitors can also be automatically positioned for fixed systems. They can pump up to and slightly over 2,000 US gallons per minute.
Brass Caps & Plugs
Brass caps and plugs are used on fire department connections (FDC), hydrants, valves, etc., to hold water back from spraying everywhere. Brass plugs and chains are used on fire department inlet connections to keep inlet ports free of debris. It is critical that these connections and ports remain free of any obstruction that could prevent them from working properly in an emergency. Our inspections include this equipment to make sure they are not showing signs of wear and are being used appropriately.
