Hood Airflow Performance Checks

Environmental Health & Safety checks airflow performance of all campus fume hoods and subsequently issues reports on the status of the fume hoods in each UI building. EHS also rechecks airflow performance after FM operations and maintenance personnel have completed work request.

Mechanical Malfunction or Repair Requests

This is an update to previous messaging regarding fume hood repairs as they relate to the closing of Shop 216 within FM.  Please continue to send all repair requests in through the Green button on the FM@YourService portal.  Certain repairs may require FM to secure outside contractor resources. 

Fume hood replacements will continue to be sent in through the Black button on the FM@YourService portal. 

If you have any questions on using the portal, please reach out to FM@YourService

Fume Hood Maintenance List

Environmental Health & Safety checks airflow performance of all campus fume hoods annually. If a fume hood needs adjustment, EHS submits a work request to FM. Maintenance should contact EHS after adjustments or repairs are completed. EHS then rechecks airflow performance. Most hoods are successfully adjusted after one attempt. Occasionally, further maintenance is needed. Once notified, EHS rechecks hood performance after additional maintenance is completed.

The list below shows only those fume hoods that required adjustments. The table will be updated as information becomes available. Repaired hoods will remain on the list for approximately one month after the final retest is completed.
