Abstract: A protective covering to control the spread of contaminants associated with material handling equipment and containers. The protective covering may comprise at least one sheet of a flexible substantially air-tight material that may be adapted to enclose various types of material handling equipment. The protective covering may also include collectors at specific locations so as to attract and collect contaminants raised by material handling equipment while running across a floor.

Abstract: A lift has a member for supporting a material handling tool. The lift has a housing defining an interior and a longitudinally elongated slot orientated in the vertical direction. The housing has a wall encircling the slot. The member extends through the slot in the housing and moves in the longitudinal direction. A flexible closure strip has a length of at least twice the longitudinal length of the slot and is connected to the member at an approximate midpoint of the flexible closure strip and movable with the member. The flexible closure strip is in slideably sealing engagement with the slot. A pair of scroll boxes accumulates and dispenses the flexible closure strip as the member moves in the longitudinal direction. One of the scroll boxes is located in proximity to an upper wall portion of the wall and the other scroll box located in proximity to a lower wall portion of the wall.
