Imbiber Beads® Bazooka Drain Shut-Off Pipe System allows water to be discharged from containment areas. As the Imbiber Beads® in the Drain Shut-Off Pipe System come in contact with the compatible organic chemical(s) - Fuels & Solvents - they will swell, forming a blocking seal, preventing hazardous material from reaching the environment. The spent Imbiber Beads® Pipe system is then replaced in order to re-establish a pro-active system. This is especially using in the AIRE Decon™ Berm and for wash down containment areas. The Bazooka filter is designed & recommended for "Class l & II" organic chemicals only : e.g.: Gasoline, Benzene, # 1 Fuel Oil , Xylene, #2 Diesel, #2 Fuel Oil ,Jet A-1,JP-5,JP-8 Kerosene,VM&P Naphtha, etc. (DO NOT USE FOR TRANSFORMER- HYDRAULIC -MINERALS OILS)
