of carbide (the maximum permissible charge in many countries for a
portable lamp for indoor use) will yield was liberated in a room, a
destructive explosion could not ensue on ignition provided the air-space
exceeded 40 cubic metres or 1410 cubic feet, or, if the evolved gas were
uniformly diffused, 24 cubic metres or 850 cubic feet. When the walls of
the room were rendered impervious to air and gas, and acetylene was
liberated, and allowed time for diffusion, in the air of the room, an
explosion was observed with a proportion of only 2-1/2 per cent. of
acetylene in the air.
