 Work Process BB. Designated Areas

1.  Designated areas are specific locations within a laboratory for work involving particularly hazardous substances. Their purpose is to ensure that proper controls are in place and that all activities involving these higher-hazard materials are confined within the designated area.
2. Designated areas can be a piece of equipment, such as a fume hood or a centrifuge, or they can be entire laboratories. However, it is best to limit the number and size of designated areas to the minimum needed because there are additional control procedures required. Refer to Work Process M for more information.
3. The activity lead must establish and post designated areas.

1. If an entire lab has been established as a designated area, then the “Caution” Entrance Placard with the applicable icons serves as the designated area posting. See Work Process AA. Additional designated area postings are not required.
2. If only specific areas within a lab, such as a piece of equipment, fume hood, lab bench, etc. are established as designated areas (without the entire lab being so designated), then the Designated Area sign must be used for posting these specific designated areas.

4. Employees working in designated areas must be informed of the hazards and controls of the materials used.
