Abstract:
A safety cabinet for storing flammable liquids is provided with a flame arresting vent. The flame arresting vent or “flame arrestor” allows flammable vapors inside the cabinet to leave the cabinet's interior but prevents flame from flowing into the cabinet's interior from outside the cabinet.

Claim (Index 12):
A flame arrestor for a safety cabinet, the flame arrestor comprising:\n a stack of corrosion-resistant wire mesh layers inside a hollow tube, which has first and second opposing open ends and an inside diameter, each wire mesh layer of the stack of wire mesh layers being substantially planar and substantially parallel to the other wire mesh layers of the stack of wire mesh layers, the wire mesh layers abutting each other, the stack of wire mesh layers comprising:\n a first wire mesh layer comprising a first set of substantially parallelogram-shaped openings each of which has a first open area sufficient to allow gaseous molecules to pass there through; \n a second wire mesh layer comprising a second set of substantially parallelogram-shaped openings each of which has a second open area sufficient to allow gaseous molecules to pass there through, the second open area being less than the first open area; and \n a third wire mesh layer comprising a third set of substantially parallelogram-shaped openings each of which has a third open area sufficient to allow gaseous molecules to pass there through, the third open area being less than the second open area; \n wherein the wire mesh layers are substantially planar and substantially parallel to each other; and \n wherein the first, second and third open areas are sized, shaped and arranged such that, molecules of gas passing through the wire mesh layers travel along a path through the stack of which mesh layers, which is at least partially boustrophedonic and travel over a surface of at least one wire in each of the substantially parallel wire mesh layers; \n wherein the wire mesh layers are formed of non-intumescent wire such that the wire mesh layers will not swell when heated and will not seal the hollow tube when the wire mesh layers are heated.
