  • Patent number: 5359955
    Abstract: An improved spill pallet for the support of drums which contain hazardous material. The pallet provides a support surface which vertically abuts a grate upon which a number of drums are placed. Beneath the support surface is provided a number of bowl-shaped chambers which receive and contain spilled or leaked liquid. The support surface includes a peripheral rim, a series of support rails, and a central support member. The rails extend from a side wall of the pallet inwardly toward the central support member, a space or gap separating an inner terminal end of the rails and the central support member. Adjacent bowl-shaped chambers are fluidly connected by channels defined by the space between the terminal end of each rail and the central support member. The channels increase the volume available for retention and containment of liquid to at least two times the maximum volume of any drum or container placed on the pallet while the rails laterally support the side walls and help prevent deformation thereof.
