It is a federal requirement that all chemical waste containers be further protected through use of a secondary container. Secondary spill containment systems must hold 110% of the volume of the primary container in case of spills or container breakage, so select a container with an appropriate volume that holds at least 10% more than the largest bottle, carboy or drum you intend to use it with.
