- Abstract
- The manifestations of a fire in ordinary combustible materials usually appear in the sequence of first, combustion gases, then smoke, followed by flame and heat. Many fires develop through the first two stages over a considerable length of time which is known as the incipient period. Detection must occur during this incipient period if damage is to be kept to a minimu. In many instances, this slow, smoldering condition will continue until a window or door is opened. The admission of fresh air at this time produces a sudden burst of flame that generates intense heat.
