NON-FLAMMABLE AND EXPLOSION-PROOF METHANE-AIR MIXTURE

摘要

FIELD: medicine, life saving equipment. ^ SUBSTANCE: invention relates to fire and explosion protection. A non-flammable and explosion-proof methane-air mixture contains a fire retardant diluted in carbon dioxide and presented by propylene and/or isobutylene in the volume ratio of the fire retardant to carbon dioxide equal to 1 : 4-10, with the following content of said components in the protected capacity, vol %: Propylene and/or isobutylene 1.5 - 4.0; Carbon dioxide 8.0 - 15.0; Methane 4.0 - 13.0; Air up to 100. ^ EFFECT: lower consumption of the retardant. ^ 1 tbl
