Biohazard bench

A safety cabinet is a laminar down flow cabinet, which is constructed specifically for protection of both the sterile product and the operator. It is frequently used in (hospital) pharmacies for aseptic preparation (when products are not fully closed) and for aseptic handling of class 4 or 5 substances (see Sects. 26.5.2 and 26.8). Laminar down flow has the advantage compared to cross flow that the operator does not feel the continuous flow in his direction. Other names for a safety cabinet are biosafety cabinet, biosafety bench, biohazard bench, biohazard cabinet, biological safety cabinet etc. 

Animal carcasses, bedding and absorbent material from bench tops should be wrapped in biohazard containers and prepared for disposal by incineration. 

All floors, laboratory benches, and other surfaces in areas where biohazardous materials are handled must be disinfected upon completion of operations involving plating, pipetting, centrifugation and similar procedures. 

Minor spills that occur on a bench top can be wiped up with a decontaminant-moistened towel. The use of absorbent bench-liner will help contain small spills. These surface covers can be moistened with decontaminant after a spill and placed in the biohazard waste.
