Biosafety Program Mission Statement
The University of Vermont Biosafety Program’s primary mission is to support laboratory research by assuring the safety of research operations involving biohazardous materials, the people involved in that research, and the public and environment where that research is conducted. We strive to provide excellence in a wide range of quality services that include biosafety training, IBC and IACUC registration & SOP reviews, risk assessments for laboratories and vivarium, and regulatory guidance for research and teaching activities involving biohazardous materials.
Biological Safety
Biological safety or biosafety is the application of knowledge, techniques and equipment to prevent personal, laboratory and environmental exposure to potentially infectious agents or biohazards. Biosafety defines the containment conditions and work practices under which infectious agents can be safely manipulated. These pages serve as the biological safety manual for the University of Vermont. They should be used as a primary reference for any work involving biohazardous materials used at UVM.
Biohazard
Infectious or etiologic (disease causing) agents, potentially infectious materials, certain toxins and other hazardous biological materials are included in the definition of a biohazard. Biohazardous agents may include but are not limited to: Certain bacteria, fungi, viruses, rickettsiae, chlamydiae, parasites, recombinant products, allergens, cultured human or animal cells.

Biohazard Spill Response
General Spill Response
It is important to have a plan of action before an emergency occurs.
In the event of a biological spill, only properly trained personnel should attempt cleanup, and then only if the appropriate tools, PPE, and disinfectants are available. If in doubt, or if the spill is unmanageable, call Service Operations (SOS) at 802-656-2560 to have Environmental Health & Safety (EHS) staff paged. Know the risks and proceed with the appropriate response. This can save you valuable time during an emergency situation.
For a life-threatening emergency, call 911.
Be Prepared
It is important to have a plan of action in the event of an emergency. Knowing the risks and the appropriate response can save you valuable time during an emergency situation. Purchase biological spill kit materials so they are available in your laboratory. Biological spill cleanup materials are not provided by EHS. A biological spill kit should contain the following:
- Disposable gown
- 4 mil Nitrile gloves, at a minimum
- Disposable face shield
- Shoe covers/booties
- Spill pads or other absorbent material
- The appropriate disinfectant for agents used in the lab. Read the Pathogen Safety Data Sheet.
- Tongs, forceps and/or small broom and dustpan to pick up broken glass (sharps)
- Sharps container
- Red Biohazard bags
Spill Assessment
Not all spills of biological materials present the same risks to personnel and/or to the environment. The volume of the spill is not necessarily the most important factor. In addition, the following should be taken into account:
- Location of spill
- Nature of the affected surface(s)
- Infectivity or toxicity of the material spilled
- Degree of aerosolization resulting from the spill
- Complicating materials (broken glass, chemicals, clothing)
- Ability to sufficiently and effectively disinfect the area
In any spill scenario, the safety of personnel is the most important consideration!
Spill Clean Up
Small spills (less than 500 mL) inside the laboratory
- Keep others away from the spill area
- Don appropriate PPE (gloves, lab coat, shoe covers, face shield)
- Gently cover the spill with absorbent material, such as paper towels or spill pads
- Mix a fresh solution of the disinfectant that is appropriate for the materials spilled.
- Pour (do not spray) the appropriate disinfectant over the spill; start at the outside and work towards the center.
- Allow 20 minutes of contact time
- Use tongs, forceps, or dustpan to clean up any broken glass.
- Place broken glass in a sharps container.
- Dispose of debris contaminated with the biological material into a red bio bag. (used spill pads, paper towels, gloves, etc)
- Apply more disinfectant and wipe the area clean again.
- Wipe down any tools or equipment used with disinfectant, allowing for appropriate contact time.
- Place red bag(s) filled with contaminated debris into biowaste box.
- Thoroughly wash hands with soap and water
Large spills (over 500 mL) inside the laboratory
- Immediately evacuate the lab, close the door behind you, and post a do not enter sign on the door
- If the laboratory in not under negative pressure, cleanup should begin as soon as possible to minimize the spread of aerosols. Always don PPE first.
- Call SOS at (802) 656-2560 and report the spill. Have them page EHS staff.
- Remain at a safe distance and wait for responders to arrive. They will need any information you can provide.
Spills in a centrifuge
- Close the lid and allow aerosols to settle for at least 30 minutes
- Don appropriate PPE (disposable lab coat, face shield, gloves)
- Transfer the rotor and buckets to a biosafety cabinet for disinfection
- Thoroughly disinfect with an appropriate disinfectant, allow 20 minutes of contact time
- Discard all cleanup materials and used PPE as biowaste
- Thoroughly wash hands with soap and water
Spills involving sharps
- Don appropriate PPE (gloves, lab coat, shoe covers, face shield)
- Never pick up sharps by hand. Use tongs, tweezers, or a dustpan to avoid direct contact.
- Dispose of any larger pieces of broken glass into the sharps container. Cover the remaining area with absorbent material, such as paper towels or spill pads.
- Pour (do not spray) appropriate disinfectant over the spill, starting at the outside and working towards the center.
- Allow 20 minutes of contact time
- If broken glass was involved, there still may be small pieces present. Carefully collect the used spill pads with tongs.
- Discard used spill pads as biowaste
- Apply more disinfectant and wipe the area clean
- Wipe down any tools or equipment used with disinfectant
- Dispose of all clean up materials and used PPE as biowaste
- Thoroughly wash hands with soap and water
- For more information on sharps, please refer to the Sharps Safety page.
Spills inside of a biosafety cabinet
- Make sure you are wearing appropriate PPE (disposable lab coat, face shield, nitrile gloves)
- Allow the BSC to run continuously during cleanup
- Gently cover the spill with paper towels or spill pads, do not allow the spill to spread.
- Apply appropriate disinfectant and allow 20 minutes of contact time
- Disinfect all interior surfaces of the BSC
- Dispose of all clean up materials and used PPE as biowaste
- Thoroughly wash hands with soap and water
- Allow BSC to run for 10 additional minutes before resuming work or shutting off
Spills outside of the laboratory
- Immediately clear the area of all persons and secure the area.
- Call SOS at (802) 656-2560 to have safety staff paged
- Cleanup should begin as soon as possible to prevent the spread of aerosols.
- Only attempt cleanup if the appropriate tools and PPE are available.
Please refer to our Transporting Biological Materials page for proper transport procedures.
Transporting Biological Materials
Inside of Your Lab
Primary containers that have lids are acceptable for moving biological materials within your own lab. Ideally, the container should not break or open if accidentally dropped.
Outside of Your Lab (Same Floor)
Moving biological samples or materials outside of your lab requires secondary containment. The primary containers should be placed inside of a secondary container with a lid (a tupperware-type container may work well). The secondary container should be sturdy enough that it will not break, open, or leak if accidentally dropped. The container should be made of a material that is easy to decontaminate.
Secondary containers must be decontaminated before being removed from the laboratory.
Outside of Your Floor or Building
Moving biological samples or materials to a different floor or building also requires tertiary containment. The secondary container (as described above) should be enclosed in a tertiary container that will not break, open, or leak if accidentally dropped. (An igloo-type cooler may work well). The container should be made of a material that is easy to decontaminate.
Tertiary containers must be decontaminated before being removed from the laboratory.
PPE
PPE should never be worn to transport samples or materials outside of your lab. Decontaminate the outside of your containers before you leave the lab.
Bring new PPE with you to put on once you arrive at your destination.
Biohazardous Agent Reference Documents
BARD Info
The Biohazardous Agent Reference Document (BARD) is a guidance resource that reviews and summarizes the nature of a pathogen or biotoxin and offers safety requirements for work with the agent in the laboratory. The document includes characteristics of the agent, laboratory and health hazards, precautions, containment and PPE requirements, spill and disinfection procedures, exposure procedures and required follow-up, and additional references. The BARDs provided here are general templates, and laboratory-specific BARDs may be created by the IBC to address any additional risks or requirements specific to the research in each individual laboratory.
The BARD is provided as an additional guidance tool, and is not a substitute for a risk assessment, biosafety training, lab-specific training, or a formal IBC master protocol registration. This document should be readily available in the laboratory, and it is the responsibility of the Laboratory Supervisor or Principal Investigator to ensure that all lab personnel have read, understood, and signed the document. The BARD is for informational purposes only and is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Please consult a health care provider for any medical questions or concerns.

Risk Assessment and Containment
Risk Assessment Factors
Risk Assessments are conducted on a case-by-case basis due to the large variety of labs, equipment, and research being conducted at the University. Many factors are taken into account during a risk assessment, some of which are independent of each other, and some of which rely heavily on other factors:
Amount and Concentration of Agent
- Based on the infectious dose and ability of the agent to cause disease
Route of Exposure
- Which routes of exposure are possible?
- What can be done to reduce or eliminate these risks?
Diagram below shows exposure pathways of hazardous substance through inhalation, ingestion and dermal exposure (example hand exposure).
Pathogenicity and Virulence
- How easily can the agent cause disease?
- How serious is the associated illness?
Associated Disease
- What are the possible outcomes of an exposure to the agent?
- Are there vaccines or post-exposure treatments available for the disease or illness?
Infectious Dose
- How much of this agent does it take to make someone sick? (For example: the infectious dose for Salmonella is about 100,000 organisms, while the infectious dose for Cryptosporidium is 1 - 10 oocysts)
How The Agent Will Be Used
- Is aerosol production possible?
- Will a biosafety cabinet be used?
- Will this agent be used in an animal model?
- Will sharps be used?
PPE
- Is the PPE used in the lab appropriate for this work?
- Is contaminated PPE managed in a safe manner?
Experience Level of Researcher(s)
- Do lab personnel have prior experience with this agent or this type of work?
- Have lab personnel had the proper training for this work?
- Is there a Standard Operation Procedure (SOP) in place?
- Are lab personnel proficient and comfortable with the procedures to be performed?
Biosafety Levels and Risk Groups Info
There are four biosafety levels and four risk groups, as defined in the BMBL. Biosafety levels describe the practices, equipment, and facilities used for work with biological agents. Risk groups describe the potential effect of the biological agent on human health. The biosafety level generally corresponds to the risk group, but not always. Biosafety level is dependent on a risk assessment by safety staff. The biosafety level or laboratory practices maybe elevated if there is an increased risk of exposure. Each biosafety level builds upon the previous one.
Questions? Contact safety@uvm.edu for assistance.
Risk Groups
Risk Group 1
Agents that are not associated with disease in healthy adult humans (E. coli K12)
Risk Group 2
Agents that are associated with human disease which is rarely serious and for which preventive or therapeutic interventions are often available (Salmonella)
Risk Group 3
Agents that are associated with serious or lethal human disease for which preventive or therapeutic interventions may be available (high individual risk but low community risk) (Hantavirus)
Risk Group 4
