The Division of Occupational Health and Safety (DOHS) 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.
Any maintenance or similar work in a laboratory that requires the entry of maintenance or other staff that is not knowledgeable about laboratory safety and/ or aware of potential hazards in the space.
In addition, for BSL-2 laboratories, work on ventilation equipment, and re-occupancy 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.
Clearances are not performed or required for the removal or maintenance of Biosafety Cabinets. Instead, place a Service Request for gaseous decontamination of a Biosafety Cabinet rather than submitting a clearance. Please note this link is only accessible on the NIH Intranet.
Submit all laboratory clearance requests through
PI-Dashboard. Contact your Safety & Health Specialist for additional information.
