Abstract

A sorbent pad for protection against environmental damage by drums of hazardous waste is disclosed. The sorbent pad comprises sorbent fibers and, on the bottom, a barrier layer. The drum rests on the sorbent pad and any spills or condensation are sorbed by the sorbent pad. The barrier layer prevents any sorbed material from leaching through to the pallet, floor, etc. on which the drum rests.
