ABSTRACT:
Improved techniques are provided for improving the environment of hazardous material abatement personnel operating within an enclosed working area while conducting, for example, asbestos removal operations. A negative pressure is established within the working area by a portable air moving unit, which exhausts air from the working area to prevent hazardous material leakage. The exhausted air is filtered, a significant portion of the exhausted air is conditioned by a portable refrigeration, heating and dehumidification system, and the temperature controlled air is returned to the working area. An air diverter is provided for regulating the ratio of the discharged air to the returned and conditioned air in response to the sensed pressure level within the working area. The temperature of the working area is regulated, thereby substantially increasing worker productivity and reducing safety risks. The humidity level within the working area may either be lowered to reduce the curing time for hazardous material final encapsulation operations, or increased to reduce the airborne contaminant level during wet abatement operations. Leakage from the working area is preferably minimized, while the efficiency of the portable conditioning unit is maximized.
