Introduction
Fire is very useful in man’s existence in planet Earth. During incient time, Hominid (great apes) is the group of people discovered fire. They used fire to keep them warm and to protect them against wild animals. As the time passed by, they discovered that fire can be used to cook food. Until now, people used it in daily live, and many other things that need the benefits afforded by fire. While fire has helped much in shaping and developing the country’s industries, it has also become a threat and has claimed numerous lives and properties.

The degree of usefulness which fire possess is conditioned by the care which man applied in handling it. As such, the task of fire prevention/control has become a pressing concern of the government. This is so, in the face of the alarming figure of losses yearly resulting form reported conflagrations. The threat of conflagration is greater in cities and municipalities.

Arson is an inherently difficult crime to detect and prosecute, and it falls between police and fire department responsibility. Both the police and fire services can legitimately claim authority in arson cases, but each also may rationalize that the responsibility belongs to the other. The police/law enforcement spends additional time and money trying to bring arsonist to trial, and the arson investigator need cooperation and better training to solve an arson crime.

Body
Fire investigation is by nature the basis for fire prevention program. Only an in-depth analysis of what sequences of events enable it to spread, and how and where it was controlled (e.g. firefighting, structural design lack of fuel) can help prevent future fires. One of the most difficult problems to solve is to determine the cause of the fire, since the flames generally consume any evidence of what occurred. This is the reason that the cause of most fires cannot determined without a long and careful investigation. Cause arson is a crime against either persons or properties. It may be defined as the malicious burning of another’s property or the burning of one’s own property with intent to injury or defraud the insurer of that property. Arson may include the burning of all kinds of buildings, structures, aircraft, watercrafts, crops, forest land and personal property. So no matter how small, fire must be investigated.

Fire investigations provide authorities with information needed to guide fire prevention education programs, help fire inspectors in spotting and eliminating new or previously overlooked hazards, and develop meaningful information for training fire protection personnel.

As far as fire investigation is concerned, they must be defined as: Cause - that which made the fire start, and Reason - that which led to the cause of a fire (a motive leading to the action)
Both cause and reason must be established to satisfactorily complete a fire investigation. The “cause” explains the existence of fire, or the WHAT of investigation; while the “reason” establishes the WHY of the fire, and also to provide guidance in establishing corrective action to preclude a recurrence of the incident.

By knowing the classes of fire a certain material will fall into, you will be able to make intelligent firefighting decisions.

Base on Burning Fuel (four classes of fire): Class A- Fires in ordinary combustible materials such as wood, cloth, and paper; Class B- Fires in flammable petroleum products or other flammable liquids, gasses or greases; Class C- Fires involving energized electrical equipment; Class D- Fires in combustible metals, such as magnesium, titanium and sodium.

Base on the Fire Causes: Natural Fire- fire caused naturally without human intervention or aid; such as lightning, spontaneous ignition, mechanical malfunction of equipment; Accidental Fire- fire causes where human action is involved directly or indirectly. Example: a.)Careless disposal of smoking materials; b.)workers using welding-cutting...
