Biosafety @ EH&S
- When 3/4 full or within 7 days, securely tie medical waste bag with overhand knot or gooseneck tie. Pretreat, if BSL2+.
- Decontaminate transport container and transport to a Medical Waste Accumulation Site.
- Dispose bag in SafeShield Containers. Ensure all closure and/or locking mechanisms are engaged. Do not put loose sharps in these containers. Do not let bags stick out of containers.
What We Manage
- Institutional Biosafety Plan (IBP)
- The Institutional Biosafety Plan (IBP) provides guidance on requirements for the safe use of regulated biological materials in research and teaching at UCLA. The IBP applies to all UCLA faculty, staff, students, contract employees, and other personnel working at locations where UCLA has management of the following biological materials:
- Infectious agents (bacteria, viruses, fungi, parasites and prions) that can cause disease in healthy humans and/or significant environmental or agricultural impacts - Human and nonhuman primate materials (all fluids, tissues, excretions, secretions, primary cells or cell lines) - Select agents and select toxins (see Guidelines Regulating Select Agents & Toxins below) - Recombinant and synthetic nucleic acid molecules (see Guidelines Regulating Recombinant or Synthetic Nucleic Acid Molecules below) - Genetically modified animals and whole plants
- Biological Use Authorization (BUA) and Institutional Biosafety Committee (IBC) Approval
- A BUA is required for all research and teaching activities involving biological materials described in the IBP. BUAs must be submitted using SafetyNet and approved by the Institutional Biosafety Committee (IBC). More information can be found in the Institutional Biosafety Plan: Chapter 2.
Go to SafetyNet
- Biosafety Levels (BSL)
- All work practices and procedures must comply with the BSL containment standards outlined in the table below. More information on Animal Biosafety Levels (ABSLs) and Plant Biosafety Levels can be found in the Institutional Biosafety Plan: Chapter 5. Additional guidance is provided upon request.

- Biosafety Site Visits
Schedule an appointment with EH&S Biosafety
Biosafety Review A comprehensive review of the facilities, equipment and practices covered under each BUA is required when a new facility is set up and every 3 years thereafter or whenever significant changes are made that affect the risk assessment (e.g., containment level change, new major equipment or operations).
During the review, EH&S Biosafety works with the PI or a designated representative to evaluate the efficacy of the biosafety program and to ensure that facility standards are maintained, engineering controls are utilized effectively, and risk mitigation plans documented in SOPs are implemented and meeting the needs of personnel.
Following reviews, EH&S Biosafety will generate reports to summarize the findings. A follow-up visit will be scheduled within 30 days to address any outstanding issues. The IBC may choose to investigate repeat findings as outlined in the Policy on Investigating Allegations of Noncompliance.
- Guidelines Regulating Recombinant or Synthetic Nucleic Acid (r/sNA) Molecules
Recombinant or synthetic nucleic acid (r/sNA) molecules are constructed outside of living cells. They are made by joining DNA or RNA segments (natural or synthetic) to DNA or RNA molecules that can replicate within a living cell.
It is mandatory that all UCLA researchers working with r/sNA molecules follow the National Institute of Health (NIH) Guidelines on Research Involving Recombinant DNA Molecules.*More information on risk groups can be found at PHE Risk Group and the ABSA Risk Group Database.

- Guidelines Regulating Escherichia coli Strain (E. coli)
- The the National Institute of Health (NIH) Guidelines on Research Involving Recombinant DNA Molecules states that with some exceptions, experimental use of Escherichia coli (E. coli) K-12 strain and its derivatives are exempt from the requirements of the NIH Guidelines. This exempt status allows for faster review and approval of the Biohazard Use Authorization (BUA).
Below are lists of commonly used strains of E. coli and the NIH Guidelines category applicable to those strains.
Ancestral E. coli
The following E. coli laboratory strains are K-12 and therefore most research utilizing these strains is exempt from the NIH Guidelines (Section III-F, F-8, Appendix C-II).

- Guidelines Regulating Select Agents & Toxins
- Select agent and toxin regulations require that any entity, facility and personnel involved in possession, use, or transfer of select agents and toxins register with the Federal Select Agent Program (FSAP). More information on can be found in the Institutional Biosafety Plan: Chapter 3.
Tier 1 Select Agents and Toxins Tier 1 can pose as a severe threat to public health and safety, and require additional training, containment, occupational health and security requirements (see 42 CFR 73 and 9 CFR 121). Permissible Amounts of Select Toxins The UCLA IBC requires registration of permissible amounts of select toxins before acquisition of any amount to ensure proper biosafety and biosecurity measures are in place. This does not require registration with FSAP.

Dual Use Research of Concern Dual use research of concern (DURC) refers to life sciences research involving 15 designated agents and toxins and 7 categories of experiments. These agents and experiments pose a significant threat with broad potential consequences to public health and safety, plants, animals, the environment, military materials and equipment, or national security.
At UCLA, the Dual Use Review Entity (DURE) identifies DURC and implements risk mitigation measures per UCLA Policy 995.
- Frequently Asked Questions (FAQs)
- How do I report an incident?
If this an emergency, call 9-1-1. To reach the EH&S Hotline, call (310) 825-9797.
How do I request a new biohazard door card?
Complete the the Biohazard Door Card Request form. These door cards are for sub-rooms. If the door is public facing, complete the Universal Door Card Request form.
How often should my Biosafety Cabinet (BSC) be certified and how do I get it certified?
BSCs should be certified annually. A TSS sticker on the BSC will note when it was last certified and the retest date. If your BSC needs to be serviced, please contact the phone number on the sticker.
If you have a fume hood that you would like to get serviced, email firstname.lastname@example.org to schedule a technician visit.
What should I use to disinfect?
Please see the Decontamination SOP.
I don't know who to contact. What do I do?

Is there information on how to manage core facilities?
Please see the Core Facility Management SOP.
What if I can new personnel?
New personnel can use the Site Safety Orientation Checklist.
What training do I take if I will perform BSL-3 experiments?
The BSL-3 training program is an extended mentorship and competency testing plan, which is conducted over several weeks in one of the UCLA BSL-3 facilities. Currently, the biggest prerequisite is to have an approved project which will take place in a UCLA BSL-3 lab at some point in the coming months. You can have whoever is coordinating your lab's BSL-3 experiment get in touch with the UCLA High Containment Director about scheduling your training. Please visit the High Containment website for more information.
