ROTO PEEN Scaler and VAC-PAC SYSTEM

Category: Decontamination > Mechanical Surface Removal > Scabbling , Mechanical
Reference # : OST # 1943 DOE/EM-0343 Model No : ROTO PEEN- VAC PAC

The ROTO PEEN Scaler and the VAC-PAC waste collection system, is a fully developed and commercialized technology used to remove hazardous coatings from concrete and steel floors, walls, ceilings, and structural components. The ROTO PEEN Scaler, the basic hand-held tool, weighs 6.5 lb, has a cutting width of 2 in, is pneumatically driven, and works with a variety of interchangeable cutting media such as cutting wheels and 3M TM Heavy-Duty Roto Peen Flaps. It was designed to remove lead-based paints and radioactive and other hazardous contaminants from flat areas and large vertical surfaces, including the interface near walls and within confined spaces. The ROTO PEEN Scaler operates independently or in conjunction with the Pentek VAC-PAC ® waste collection system. The VAC-PAC® high-efficiency particulate air (HEPA) filter and vacuum system is a portable unit offering two-stage positive filtration of hazardous particulates, including radioactive particles and lead-based paint. The VAC-PAC® also has a patented controlled-seal drum fill system, which allows the operator to fill, seal, remove, and replace the waste drum under controlled vacuum conditions. Skills and training required to operate the Pentek milling technology are minimal because the equipment is relatively easy to operate.

Benefits

* Simultaneous collection of dust and debris * Small removal gap * Reduced waste generation when compared to the baseline technology (mechanical scabbling) * Reduces the amount of airborne contamination * The technology is best used in confined areas under or around obstacles * Easily disassembled for decontamination * Flaps are easily replaced * Engineering control and no respiratory protection required during operation. * Eliminated the generation of waste and protective clothing to enter the areas, as well as decreasing the man-hours necessary to maintain the posted areas, helping to decrease costs

Limitations

* Operator have to work on their hands and knees * Very labor intensive
