Abstract
An apparatus and method for transporting hazardous, toxic or nuisance materials from the controlled chambers of removal sites to disposal sites and containing these materials by controlling the environment within the cargo area of a transport vehicle and for some distance outside it. The apparatus comprises a cargo chamber to control leakage and air flow, a regulated air handler to maintain a predetermined vacuum pressure within the cargo area relative to outside ambient pressure, a filtering system to trap air borne particles before exhausting into the outside environment and a wetting means, filter means and containment process for larger contaminates. The unit is self sufficient to provide its own generated electricity, liquid flow supply and automated control process enabling the containment system to function under stationary or mobile conditions for extended periods.
