Introduction:
Man has known fire and has used it in his everyday life without knowing that a day would come to see fire a source of death. Fire accidents are of the oldest problems that faced humankind; scholars duly studied and researched such phenomena.
Since man is natured to protect his life and property, he developed methods of dealing with new technology, and with what have been produced regarding flammable materials. Such materials together with the expansion of building and construction increased fire problems.
Whenever man advances and develops, the cost of such developments is increasing in terms of catastrophes. Wars displaced many peoples; lots died because of hunger and scare; and thus, the need to form a body to manage disasters emerged. Co-operative societies and governments began forming such a body. The Security Committee was one of the first organizations in history that combated fire in the Roman Empire.
In Saudi Arabia, a Royal Decree formed the first Civil defense Unit in Makkah on 1/1/1446H.
