Summary According to the author of ‘ http://en.wikipedia.com/ ,’ fire prevention is a safety and of the hazards associated with fires”. The prevention entails the knowledge of fire behavior, suppression, compartmentalization and investigation and its mergence not forgetting the research, development, production, testing and application of mitigating systems. The writer further says”. The owners of the buildings should maintain them according to certain builder’s instructions that are in form of laws. All buildings show be constructed as per the instructions given by building engineers and the constructors must obtain a recommendation from the construction engineers. This calls for inspection of the whole building before it is considered ready for shelter or business. The constructors must ensure that these buildings are properly maintained the necessary equipment for fire fighting is available and ready for use. Most preferable, the alarm system should be installed in every floor of the building to alert the fire fighters incase of an emergency of fire Fire prevention measures In his article about fire prevention measures, Gary Taylor says, “as the primary importance of any fire protection measure is to provide an acceptable degree of life safety to inhabitants of a structure, in most countries legal requirements applying to fire protection are based on life safety concerns” These features he is talking about should allow the owners of the buildings from physical damage. However, the owner has the right to use all means to ensure safety of his building and the properties. Therefore he has an obligation to take any necessary and affordable measures that will help him prevent the damages caused by fire. Technology growth has become a good solution to the so many problems faced by the owners of these buildings. After the buildings have been constructed according to the defined guidelines, the owners are advised to put use the current technology to help prevent fire damages. This is by using fire detection and alarm system which serves a great purpose in automatically detecting and giving warnings to the occupants in the building that there is threat of fire. With this alarm the occupants are required to vacate from the building as soonest as possible to prevent loss of lives and possibly property. Gary continues to give us information about basic elements of fire detection and alarm system. According to him, these may include: a system control unit ,a primary or main electrical power supply, a secondary (stand-by) power supply, usually supplied from batteries or an emergency generator , alarm-initiating devices such as automatic fire detectors, manual pull stations and/or sprinkler system flow devices, connected to “initiating circuits” of the system control unit, alarm-indicating devices, such as bells or lights, connected to “indicating circuits” of the system control unit , ancillary controls such as ventilation shut-down functions, connected to output circuits of the system control unit, remote alarm indication to an external response location, such as the fire department and control circuits to activate a fire protection system or smoke control system. Electricity has been a major cause of fires in buildings. It matters a lot how powe
