Fire investigation

[2] Investigations of such incidents require a systematic approach and knowledge of fire science.

The difficulty of determining whether arson has occurred arises because fire often destroys the key evidence of its origin.

Many fires are caused by defective equipment, such as shorting of faulty electrical circuits.

[3][4] Car fires can be caused by faulty fuel lines, and spontaneous combustion is possible where organic wastes are stored.
