Introducing the Stinger Rail Berm™ designed to provide portable spill containment and control for bottom loading and unloading rail tank cars This lightweight containment pad is designed to provide a temporary bermed containment area around the valves below a rail tank car during loading/unloading operations. At only 80 lbs. , it can be easily lifted into place by two operators The berm provides a 4' x 4' x 12" sump area that sits in the void between the tracks directly under the valves. Should a Large release occur, captured liquid would begin to fill this berm. The spilled product would then be directed over the outside rail to an alternate compartment 4' x 18" x 12"H. This outside compartment is fitted with two " drains that includes a male CAM-LOC fitting for quick coupling of system to hoses that can transport the spilled materials to a nearby containment area.
