ABSTRACT:
An igniting mixture is provided for chemical oxygen generators used in respirators and resuscitators for making an oxygen supply available. In chemical oxygen generators the oxygen is present in chemically bound form and when needed is released in the course of a chemical reaction with the triggering of an ignition. The ignition device with an igniting mixture is normally contained in the upper part of the chemical oxygen supply present in candle form. From here, then, begins the reaction after the ignition. To ensure the storability of the oxygen generators, the igniting mixture remains thermally stable up to a temperature of 100.degree. C., but can be activated by water and also by a higher temperature. The igniting composition consists of a mixture of an alkali and metal oxygen compound selectively with an oxygen containing silicon compound, percarbonate, metal peroxide or superoxide.
