Fire control is the practice of reducing the heat output of a fire, reducing the area over which the fire exists, or suppressing or extinguishing the fire by depriving it of fuel, oxygen, or heat (see fire triangle). Fire prevention and control is the prevention, detection, and extinguishment of fires, including such secondary activities as ...
Ventilation is a part of structural firefighting tactics, and involves the expulsion of heat and smoke from a burning building, permitting the firefighters to more easily and safely find trapped individuals and attack the fire. It is frequently performed from the outside of a burning building while the fire is being extinguished on the inside.
This process keeps the cooling water in the reactor, making it unnecessary to use powered feedwater pumps. The water in the open pool slowly boils off, venting clean steam to the atmosphere. This makes it unnecessary to run mechanical systems to remove heat. Periodically, the pool must be refilled, a simple task for a fire truck.
A critical calculation in light of the axiom that an ordinary fire will not be extinguished unless there is sufficient water to remove the heat of the fire. Fire gas ignition: ‘an ignition of accumulated fire gases and combustion products, existing in, or transported into, a flammable state. There are a wide range of events that can be ...
A fog nozzle. A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets.By doing so, its stream achieves a greater surface area, and thus a greater rate of heat absorption, which, when compared to that of a smoothbore nozzle, speeds its transformation into the steam that smothers the fire by displacing its oxygen.
In this type of system, the water circulating inside the water loop removes heat from the condenser of the heat pumps whenever the heat pumps are working in the cooling mode, then the externally mounted cooling tower is used to remove heat from the water loop and reject it to the atmosphere. By contrast, when the heat pumps are working in ...
Control includes denial of oxygen, addition of extinguishing agents, and removing heat sources. In case of chimney fire, the local fire department should be called immediately: there is a risk of the chimney failing, and/or overheating adjoining structures, which could cause the fire to spread to other parts of the building.
Fire stations frequently contain working and living space for the firefighters and support staff. In large U.S. cities, fire stations are often named for the primary fire companies and apparatus housed there, such as "Ladder 49". Other fire stations are named based on the settlement, neighborhood or street where they are located, or given a number.
