Upon completion of the new fume hood installation project and before the third-party ASHRAE 110 test is scheduled, a VAV, CAV, or High Performance Fume Hood Checklist needs to be filled out (page 1 only), signed by project manager, and returned to EHS (see the instructions on the form). These forms are used to ensure that hood and its components are properly installed and adjusted, room air and cross drafts are properly balanced, and hoods meet required exhaust flow. All calibrations and adjustments must be finalized before the third-party ASHRAE 110 test is scheduled. The third-party ASHRAE testing company will fill out page 2 of the form and turn it in as the temporary test report.

It is critical to post all newly installed hoods with a “Do Not Use” sign during the project. Sign will be only removed by EH&S, after successful final test and inspection results.
