Storm culvert inflatable bladders are designed to plug culvert pipes so as to prevent the spill from traveling through the pipe and spreading contamination. The trailer inventory includes three bladders in 12", 18" and 24" diameter. These bladders have fittings that connect with the air hose and air compressor and are best deployed on the side closest to the plume. Care should be taken when inflating the bladder by wearing the proper safety equipment. Lines should be attached to the bladder rings to assist in deployment and retrieval.
