Exposure Control Device (ECD) refers generally to all ventilated devices (engineering controls) designed to protect users from hazardous materials (vapors, gases, dusts, heat, etc.). Types of Exposure Control devices can include:
- Laboratory Fume Hoods
- Biological Safety Cabinets*
- Snorkel Exhaust Hoods
- Vented Gloveboxes
- Vented Gas Cabinets
- Downdraft/Backdraft Tables
- Dust Collection Systems
Note: This list is non-exhaustive, contact indhyg@ehs.ucla.edu if you are unsure whether your device is considered an ECD.
*Some devices such as biological safety cabinets and gloveboxes required vendor certification prior to the ECD certification program curtailment and are unaffected by this change.
Exposure control devices must be certified annually. Certification is valid until the last day of the same month of the following year. E.g. a device certified on October 10, 2025, must be recertified by October 31, 2026.
Vendor information can be found in Bruin Buy Plus. Search for vendors in the Vendor Agreements List under “Lab Contamination Control Services”. Additional vendors may be added to Bruin Buy Plus in the future.
Please contact the vendor to request a quote. Once a quote is received, proceed through the normal purchasing process.
The UC system has contracted flat rates per-device with each vendor found in Bruin Buy Plus. These prices are negotiated annually and subject to change.
Training will be affected. The corresponding modules are scheduled to be updated by the training development team.
The vendor will make the determination whether present materials will negatively impact the device’s ability to be tested. This should be discussed with the vendor prior to scheduling testing.
The vendor will determine the appropriate testing procedure for each ECD. For example, for a standard chemical fume hood, the vendor will perform face velocity and smoke visualization tests, and for variable air volume (VAV) fume hoods, an additional test is required to ensure the hood is automatically responding properly.
Submit a Facilities Management Service Request to address the deficiency. Service Requests can be submitted online at the UCLA Facilities Management Service Request Portal, or using the UCLA 311 Mobile App. For step-by-step instructions on using the UCLA 311 Mobile App, please view the following guide: Submit a Facilities Service Request using the UCLA 311 Mobile App
If the device fails due to items and materials stored in the hood, it is the device owner’s responsibility to remove and store the materials in the appropriate location. Contact laboratorysafety@ehs.ucla.edu for guidance on proper fume hood storage practices.
IMPORTANT: If a hood has been commissioned for radioactive material use, please contact fumehoods@ehs.ucla.edu prior to submitting a service request.
If the airflow monitor begins to alarm, the sash should be closed and a trouble ticket should be submitted to Facilities Management. Next steps should be taken once the cause of the alarm has been determined.
The status of your ticket can be tracked in the UCLA 311 app, or on the Facilities Management website. You can also call or email the Facilities Management Customer Service team. Details on ticket tracking and Customer Service information can be found below
If a request has not been addressed in 10 or more business days, you may contact UCLA EH&S at fumehoods@ehs.ucla.edu. Please provide the ticket number in the email. The ticket will start with an “R” followed by seven numbers, e.g. R1234567.
Yes, each device must be certified to be in compliance prior to resuming use. The vendor will charge for recertification services.
If a vendor is non-responsive, attempt alternate contact methods such as phone or email, or seek services from an alternate vendor.
Device certification will be checked by EH&S during regularly scheduled lab inspections. If a device is not certified, the normal escalation process will be followed.
