Fabrication of Fire Safety Sprinkler System in Cars
Published on Feb 05, 2017
In this these we are discussed about to avoid fire accident in cars, so we are planned to place the fire sprinkler in the car. At the same time, for this process water is most important for the resistance from fire. So we are planning to implement small water tank over the car.
A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly designed, and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone.
There are a high number of car parks being utilized and the fire load is immense. Highly flammable materials, such as plastic, rubber, textiles, have been used in the vehicles’ production - all of which have a high potential for fire development and smoke production. In addition, passenger vehicle tanks are filled with combustible fuel. Fire quickly develops through negligence (discarded lit cigarettes or carelessly placed highly flammable materials coming into contact with the hot motor components of the parked passenger vehicles) or through a technical defect (faulty power cable, leaky petrol lines or tanks, new electric power systems with increased danger of short circuiting due to high capacity batteries). If a fire is generated under these conditions, it will in certain circumstances quickly spread and ignite neighboring vehicles.
The hot, dense smoke rapidly blanketing the entire building complex makes firefighting more difficult and the emergency exits less visible. It is not uncommon for a “flashover” to occur in a fire in car parks. The fire then suddenly develops from its formation phase to the full-blown fire phase; it burns throughout the building, instantaneously covering a large area, room temperatures reach many hundreds of degrees Centigrade.
Fire safety is one of the key issues when designing buildings. Car parks, open or enclosed, are typical in modern urban environment. Car fires have been studied since numerous years. The study of the heat release rate (HRR) of cars has begun only with car tests of VTT in Finland 1991 [Mangs & Loikkanen, 1991]. After that many researches have been completed and a wide summary of car fires is in [BRE, 2009]. Wide literature and interesting statistical data from New Zealand is given in [Li, 2004]. Not only cars, but also parts of cars, such as tires [Gratkowski, 2012] and engine compartments [Weisenpacher et al, 2010] have been studied. Proper heat release rate with respect to time from ignition is the main property when modeling fires, generally.
In this model we are designed one water tank in the top of the car body, which is normally used to store the water. There we are implement the sprinkler it is normally as a product available in markets. When the heat or the temperature is normally increase in the car, or otherwise, if it any fire accident occur inside of the car means, it send the signal and the sprinkler open and the stored water will spray inside the car.
