Snyder, R H

A method of substantially precluding accumulation of combustible hydrocarbon vapors in the air of a closed substantially empty holding tank is described comprising: placing an effective combustion preventing amount of vulcanized rubber particles in the size range from 6 mesh to 200 mesh in contact with the hydrocarbon vapors within the holding tank, and, absorbing the vapors emanating from residue in the tank whereby a sufficient amount of the vapors are absorbed into the vulcanized rubber particles to ensure that the hydrocarbon vapor/air ratio is below the explosive envelop.
