Abstract: A skid steer loader comprising an improved loader main frame and including an operator's compartment designed to present a low profile vehicle particularly suitable for low clearance applications. The loader main frame includes a center compartment partially defined by a pair of longitudinally extending, laterally spaced side beams. The engine for the vehicle is mounted at the rear of the center compartment and is acoustically enclosed by structural elements of the frame. A seat pan mounted on the side beams overlies the engine and transmission and separates the operator compartment from the center compartment. At a forward end of the center compartment an elongated transmission case forms a partial bottom wall and also encloses the chain and sprocket drive system of the vehicle. The side walls of the transmission case are displaced from the side walls of the frame, enabling the operator to straddle the case, thus reducing height requirements for both the operator compartment and the overall vehicle.

Abstract: A decontamination system in combination with a work space maintained at subambient pressure. An inner vestibule is connected to the work space via a first portal, which can be selectively opened and closed by a first door. A middle vestibule, in which at least one shower bath is installed, is connected to the inner vestibule only via a second portal, which can be selectively closed by a second door or opened. An outer vestibule is connected to the middle vestibule only via a third portal, which can be selectively opened and closed by a third door, and to an ambient space only via a fourth portal, which can be selectively opened or closed by a fourth door. Each door is a rigid door. Except for the third door, which seals the third portal when the third portal is closed by the third door, each door has fixed louvers allowing small quantities of air to infiltrate.
