A fume hood adapted to be connected to an exhaust system has a ventilated chamber having an access opening, and at least one horizontally sliding sash or panel at the access opening that is configured to cover and uncover portions of the access opening. Each horizontally sliding panel has a peripheral edge that convexly curves into the chamber towards a centerline of the at least one horizontally sliding panel. In some embodiments, the peripheral edge is convexly curved in an arc of between about ninety degrees and about one hundred eighty degrees (90°-180°). The exhaust system creates air flow into the chamber and the curved peripheral edge produces controlled air flow patterns into the chamber. The curved edge is aerodynamically designed to help shed vortices and prevent accumulation of concentrations on the inside edge of the each panel typical of conventional fume hood sashes/panels.

An air evacuator includes a dome having an exterior surface, an interior funneling surface, an air intake end, and an air outlet end, the dome being significantly wider at the air intake end than at said air outlet end. An inlet allows air from outside the air evacuator to be drawn into the dome. A vent tube is positioned to receive air from the air outlet end of the dome. An air pump is positioned to move air in the air evacuator and through a filter. One or more interior-aimed ultraviolet lamps positioned within the air evacuator treat and disinfect air as it is drawn into the air evacuator. A light trap extends substantially across the air intake end of the dome to prevent ultraviolet light from one or more ultraviolet lamps from shining directly out from within the dome through the air intake end of the dome.

A method for preparing decontamination measures within a room located in a building and used by people includes a planning acquisition step. Therein, a plurality of regions of use within the room are identified, and for each region an expected use intensity is determined based on previously determined parameters. In a subsequent planning implementation step, for each region of use, proceeding from the expected use intensity, a suction means assigned to said region of use and having an associated supply air volume flow is specified. In a method by carrying out the decontamination measures, while the decontamination measures are being carried out, operation of individual suction means is adjusted to an actual use of the assigned region of use by people, and a suction volume flow suctioned by the suction means in question is specified, between a minimum value specified for the suction means in question, and a maximum value.

An equipment cleaning apparatus for an extraplanetary environment includes a cleaner vessel positioned at an exterior of an extraplanetary habitat, and an exterior hatch located outside of the extraplanetary habitat and allowing access to an interior of the cleaner vessel. The cleaning apparatus is operable in one or more cleaning cycles to clean equipment located in the cleaner vessel. A method of cleaning equipment in an extraplanetary environment includes providing a cleaner vessel at an extraplanetary habitat, placing one or more articles of equipment into an interior of the cleaner vessel through an exterior hatch located outside of the extraplanetary habitat, closing the exterior hatch, and operating one or more cleaning cycles on the equipment in the cleaner vessel.

A fume extraction hood is designed to be positioned above a welding, cutting, or other metal-working location and to remove hot gases, smoke and fumes produced during these processes. The hood forms a box-like structure with an extractor rail structure disposed in an internal volume of the hood. The extractor rail structure comprises panels that force sharp turns in the gases, causing particulate matter to drop out of the gases both outside and inside the extractor rail. A primary path for gases accelerates and re-directs the gases entering into the extractor rail, and within the rail. The rail may form a dropout tray that can be removed for cleanout of collected particulate. The side and end rails of the hood may create a secondary path for gas not directly intaken into the extractor rail. This secondary path is re-directed towards the extractor rail, where gas is collected and particulate is forced to drop out as it joins the primary path.

Also disclosed are the use of the workstation for handling and/or microscopy of biological materials, such as tissue, embryos, and stem cells, as well as the use of the workstation for microbiological safety workstation in accordance with ISO/EN 12469.

The invention relates to a discharging apparatus for discharging loose and in particular pulverulent material that is hazardous to health from rigid or flexible containers (12), in particular bags and barrels (13), comprising a discharge chamber (2) which has a discharge opening (5) for discharging the material after removal from a container (12) and which additionally has an insertion opening (3) for at least partial insertion of a container (12) into the discharge chamber (2). According to the invention, the discharge chamber (2) has a ventilation opening (4) which is arranged at a side of the discharge chamber (2) opposite the insertion opening (3) and which is connected to pump means (10) in such a way that an air stream can be generated inside the discharge chamber (2), which causes a laminar air flow starting from the insertion opening (3) and leading in the direction of the ventilation opening (4).
