Before performing repair and/or maintenance of a fume hood exhaust system marked “Radiation – Danger”, consultation from the EHS Radiation Protection Service is required.
Examples of ventilation equipment with radiation signage
Contact the EHS Radiation Protection Services (RPS) Team prior to:
- Entering into the system;
- Performing any work on the exhaust system (maintenance, repairs, change of the filters, etc.);
- Disposing filters in order for RPS to confirm the proper disposal.
The RPS Team will conduct a radiation safety assessment, contamination survey as applicable, and communicate the recommendations to the worker, the supervisor, and/or the project manager.
