Abstract: A spray containment enclosure assembly for use during the spraying operation on a work surface to prevent escape of airborne particles to the environment. The assembly includes a support arm, a personnel basket sized to receive a worker therein, a rigid enclosure attached to the personnel basket. The rigid enclosure is positioned with respect to the personnel basket such that when the worker is in the forward portion, at least a portion of an upper torso of the worker is within an interior area. The rigid enclosure has an open front side that is adapted to be positioned adjacent to the work surface to form an airway gap therebetween to allow air to flow into the interior area. A fan mounted to the rigid enclosure is adapted to create negative pressure in the interior area to draw air inwardly through the airway gap.

Abstract: A moveable, rigid enclosure having a work platform enclosed therewithin and which is sealed against a work surface. A negative pressure is applied to the interior of the enclosure. The rigid enclosure is supported by the inner work platform, and includes a funnel-shaped bottom portion coupled to a conduit for collecting and transporting of spent blast materials and debris contained within the enclosure which is released during blasting of the work surface. Blast media is supplied to the worker by a supply conduit extending interior of the rigid enclosure. A controller is positioned within the enclosure by which the worker while within the enclosure can adjust the vertical or horizontal position of the enclosure.
