FIELD: chemistry.
SUBSTANCE: invention relates to pyrotechnics. The gas-generating composition for producing breathable gas contains silicon as fuel, cellulose nitrate or sodium metasilicate, or magnesium cement as binder, oxidising agent which forms nitrogen in combustion products, in form of nitrates of alkali or alkali-earth metals or their mixture with potassium perchlorate or ammonium perchlorate in ratio which ensures absence of hydrogen chloride in the combustion products.
EFFECT: invention enables to obtain non-toxic gases saturated with oxygen.
