The oxygen generation compositions are tin fueled to produce a significantly lower carbon monoxide contamination of the breathable oxygen generated. The oxygen generating compositions comprise about 0.5-15% by weight of tin powder as a fuel and rheology modifier; from zero to about 15% by weight of a transition metal oxide catalyst; about 0.1-5% by weight of an alkaline compound as a chlorine remover and reaction rate modifier; and the remainder of an oxygen source selected from the group consisting of alkali metal chlorates, alkali metal perchlorates, and mixtures thereof. The oxygen generating composition can optionally further include up to about 5% of a binder. The oxygen generating compositions have a smoother, more uniform rate of oxygen generation, lower temperature sensitivity, and a lower operating temperature than comparable chlorate/perchlorate oxygen generation compositions utilizing iron powder as a fuel.
