In order for a fire to occur, three conditions must be met. There must be a combustible (fuel), an oxidizer (oxygen), and a sufficient heat energy source (source of ignition). The key elements that determine the cause of the fire rely on the determination of the first material ignited and of the source of ignition.
Universal Fire & Safety Services Ltd, examine buildings in order to detect fire hazards and ensure that federal, state, and local fire codes are met. Fire investigators, another type of worker in this field, determine the origin and cause of fires and explosions.
