Gas 24


Gas 24 : Gas is an aeriform fluid of matter lacking independent shape or volume, which tends to expand indefinitely. The properties of gases, and their behavior, can only be explained by assuming that they are composed of extremely minute particles in constant motion - the higher the temperature, the more violent the motion. For fire protection purposes, gases are generally divided into two broad categories; flammable and nonflammable. The hazards of flammable gases are generally similar to flammable liquids and there is really no sharp line of demarcation between gases and gases of liquids in respect to fire hazard; further any actual gas, at a sufficiently low temperature and high pressure, becomes a liquid and any flammable liquid at a sufficiently elevated temperature becomes a gas
