4.3.2 Contact

Control of potential exposure by contact requires procedures be conducted in a manner that avoids contamination of body or work surfaces.  This is accomplished through the use of gloves and other personal protective clothing, protection of work surfaces with an appropriate absorbent disposable covering, using care in the performance of procedures and cleaning and disinfecting work surfaces.  Dispersal of contaminants to other surfaces can occur by their transfer from gloves of a laboratory worker, by placement of contaminated equipment or labware and by improper packaging of contaminated waste.
