The fire hydrant system is the backbone of the fire fighting system in a building or premises. The system is a water distribution system consisting of water tank, suction piping, fire pumps and a distributed piping system. The distributed piping system establishes connectivity throughout the building through fire hydrants, hoses and nozzles. The purpose of the fire hydrant system is to provide a readily available source of water to any point throughout the building. This helps in controlling fire during an emergency.
Through the fire main system, the fire-fighter is provided with a reliable and versatile system capable of providing a number of different methods for controlling the fire, water can be supplied through the fire hydrant system as a straight stream for combating deep seated fires and as a spray for combating combustible liquid fires.
A fire sprinkler system is the most effective fire prevention system since it extinguishers fire before it gets too big.
A fire can create havoc in a few minutes. This can be avoided by installing the fire sprinkler system. The fire sprinkler system is activated when heat in the room rises to a threshold-level. A fire sprinkler system douses the fire by sprinkling water on it, effectively smothering it before it spreads further.
Most people who die as a result of fire don’t actually burn to death. Predominantly, they die of suffocation from smoke inhalation. Fire sprinkler system is the only fire protection device that cuts through the smoke, weighting down larger smoke particles before they have a chance to rise. This lessens smoke thickness, making it easier to breathe.
Fire sprinkler systems are connected with water pipes on ceiling and walls. The network of water pipes is either filled with water at all times, or hooked up to the water main or a storage tank via a water pump or valve.
The sprinkles themselves are installed on ceilings or sometimes high on the walls. Each sprinkler in the fire sprinkler system is fitted with a glass bulb containing gases and liquids that expand under heat, or a fusible link with seals that melt when they contact with high heat.
When fire starts, it sends a plume of hot air toward the ceiling. This expands the contents of the glass bulb. When the gases get hot, the glass bulb breaks. In the case of the fusible link, the heat melts the seals on the links. This releases a valve connected to the water pipes in the ceiling, dousing the fire with water. The glass bulbs and link seals are often designed to break at a specific temperature usually around 68°C.
The droplets released by the fire sprinkler system ate strictly controlled to be large enough to penetrate the core of the fire without evaporating. They bring the temperature inside the fire below sustainable levels. As a result, the fire goes out quickly before it spreads to different areas of the premises.
