The laboratory should be divided into “functionally clean” and “potentially contaminated” areas, with the clean areas reserved for administrative and preparatory work. Access to the clean areas and the contaminated areas must be controlled and enforced by the laboratory’s manager.
The laboratory should be kept neat, clean and free of materials and equipment not used for performing routine work. Equipment and materials that are not being used or that do not work should be removed from work areas.
Work surfaces must be decontaminated after any spill of potentially infectious material and at the end of each work session. (See the section on spills in Chapter 8 for additional information.)
