Provide and perform all necessary labor and materials for annual on-site certification of BSCs. All “containment related” and “worker comfort and safety” related tests (except for cabinet leak test and vibration) listed in the most current edition of NSF Standard #49 shall be done. These include, but are not limited to: 1. Downflow velocity and volume test; 2. Inflow velocity test; 3. Airflow smoke patterns test; 4. HEPA filter leak tests of supply and exhaust filters. 5. Electrical leakage and ground circuit resistance and polarity tests. 6. Lighting intensity test; 7. Noise level test; Adjust exhaust and supply controls to achieve correct air balance when possible, and level BSC. Perform certification as described in A above when BSCs are relocated. Schedule certifications with the principal user of each BSC in this proposal. All services are to be performed during the hours of 8:00 a.m. to 5:00 p.m., Monday through Friday, excluding University Holidays. Additionally, the ability to provide emergency service outside of business hours upon request from principal users is preferred.
