ABSTRACT:
A vehicle for transporting hazardous materials that may yield airborne particulate contaminants, such as asbestos, includes in the disclosed embodiment a trailer having an inner surface, an outer surface, and at least one door defined therein for providing access to an enclosed space therein. An air supply is provided for forcing outside air into the enclosed space during operation, creating at a slight overpressure in the enclosed space. An outlet opening is defined in the enclosed space for permitting air to flow out of the enclosed space as a result of the slight overpressure. The vehicle also includes a filter positioned at the outlet opening for filtering airborne particulate contaminants from the air as it flows therethrough. This continuously cleans the air of airborne particulate contaminants during operation of the vehicle. A method of operation and a filter pouch for holding the hazardous material are also disclosed.
