FIELD: fire safety.
SUBSTANCE: invention relates to a fuse flashback, comprising a cylindrical flame arrester built into wall that separates an endangered area from outer area having a plurality of through-slits in its cross section and height, which determines length of bushing slots, as well as directed to explosion hazardous area lower side and directed to outer area upper side. Important case of application of fuse flashback of type mentioned at outset is that it comprises forming reinforcements, which serve for venting vessel when vessel creates pressure which must be reset for safety reasons. In this case, valve releases gas from endangered area through flame arrestor. In order that gas does not harm environment, it can be burnt directly after release from flame arrester, with aim of disposal with respect to explosiveness or combustibility due to atmospheric deflagration.
EFFECT: fuse flashback is disclosed.
