Chemical Fume Hoods

General Information

For general information on chemical fume hoods see the UI Chemical Hygiene Plan, Section 9.0 Facility and Equipment Safety.

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 Facilities Management (FM) operations and maintenance personnel have completed work request

Mechanical Malfunction or Repair Requests

The unit using the hood should directly contact the FM Work Control Center (335-5071) for problems or repair requests related to mechanical aspects of the hood such as alarms, monitors and controllers, or when the hood appears to not be operating correctly. After FM completes the work request, FM notifies EHS to recheck the hood airflow.

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 Work Control Center (WCC). 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.
