The Safety Operations and Support Branch (SOSB) routinely performs clearances to check for visible research-related hazards prior to renovations and maintenance of laboratories.

​Laboratory clearances are required before the following activities:

• Any renovation, whether partial or complete, of a laboratory;
• In addition, for BSL-2 laboratories, work on ventilation equipment, and reoccupancy of newly renovated areas;
• In BSL-3 laboratories, all of the above and prior to any housekeeping (i.e. waxing of floors) or routine maintenance of equipment.

Contact your Safety & Health Specialist for more information and to schedule a time for any laboratory clearances.

The DOHS has published a document titled Moving Your Lab...Safely to assist in the laboratory clearance process, as well as in the greater endeavor of preparing to move a laboratory to a new location. This is an excellent resource for general guidance, timelines, and contact information.
