Claims20
A spilled fuel containment apparatus, comprising:
- a drive-on substrate;
- and
- at least one side including a lower edge being substantially vertically extendable, said at least one side being substantially fluidically sealed with said substrate when said at least one side is substantially vertical, said lower edge of said at least one side not being fluidically sealed with said substrate when said at least one side is substantially horizontal, wherein the lower edge of said at least one side is hingedly connected to said drive-on substrate to facilitate the vertically extendability of said at least one side.
A method of containing a potential liquid material spill, comprising the steps of:
- driving a delivery vehicle onto a floor;
- and
- raising at least one side to be substantially vertical, said at least one side including a lower edge being substantially fluidically sealed with said floor when said at least one side is substantially vertical, said lower edge of said at least one side not being fluidically sealed with said floor when said at least one side is not substantially vertical, wherein the lower edge of said at least one side is hingedly connected to said floor to facilitate said raising of said at least one side to be substantially vertical.
