A secondary containment apparatus for use in combination with primary containers for hazardous wastes such as drums or large barrels, comprising a generally rectangular base member and two generally rectangular lid members of a size sufficient to enclose one or more primary containers. The lid members are moveable only laterally in relation to the base member, the lateral movement allowing access to the drums contained within. The lid members have interlocking means to form a releasable closure, and have engagement means for attachment to the base member. The base member is impermeable to liquids, and is preferably composed of translucent plastic for visual inspection.
