(under subclass 314) Subject matter which includes a
substance which, upon the detonation of the explosive and the release of heat or flame as a result of the explosion, prevents or minimizes the chances of the surroundings from catching fire or causing an explosion by putting out the flame or absorbing some of the heat of the explosion.
(1) Note. The substance will (a) absorb some of the heat of the explosion, or (b) volatilizes, (c) liquifies, (d) releases water of crystallization and absorbs some of the heat resulting from the explosion, or (e) forms a gas which will not support combustion.
(2) Note. The substance may be in the form of a sheath about the container.
