Transfer of biomaterials between labs, buildings, and roadways is strictly regulated by various federal, state, and local agencies. Proper packaging is essential to ensure safe transport and to avoid sample loss and accidental release/exposure.

Contact Biosafety at or (323) 442-2200 before transporting ANY biomaterial (including Biosafety Level 3). All laboratory personnel who transport or work with these materials are required to complete General Laboratory Safety (GLS), bloodborne pathogens (BBP), and packaging and shipping training as required.

Who Prepares Biomaterials for Transport?

Laboratory personnel may prepare biomaterials for transport if they are trained on use of correct packaging, safe transport of the materials, and have knowledge of emergency procedures in the event of an accident or spill.

What Types of of Biomaterials Can I Transfer?

  • Recombinant or synthetic nucleic acids, organisms, or micro-organisms
  • Blood samples or other biological fluids and diagnostic specimens
  • Cultures, suspensions, or lyophilized (freeze-dried) micro-organisms
  • Fresh or preserved cells or tissues
  • Viruses or subviral particles

What are the Packaging Requirements for Handcarrying Infectious Materials?

  • Place material in a tightly closed and secured leakproof primary container.
  • Seal the container with a tightly fitted cap and wrap closure with Parafilm™ or laboratory tape.
  • Label the primary container to identify the material.
  • Wrap each primary sample tube with enough absorbent material to absorb leakage (liquid sample).
  • Place all primary samples in a sealable, leak-proof secondary container labeled with a biohazard symbol.
  • Suitable secondary containers can include a plastic specimen bag with a zip closure or plastic container with a fitted lid.

What Precautions are Necessary for Transporting Infectious Materials Between Buildings?

  • Use a cart for movement between rooms or buildings.
  • Wear PPE appropriate for transport within the laboratory (e.g., lab coat, gloves, and eye protection).
  • For movement through public areas (e.g., between buildings or hallways), wipe the outside of the secondary container and bring appropriate PPE for use at the laboratory destination. DO NOT wear PPE in public areas.
  • Wear the minimum PPE standard (full length pants or clothing that fully covers the legs and ankles and closed toe/heel shoes) for transport through public areas.
  • Bring or have hazard appropriate lab coats, protective eyewear, and gloves for use at the destination, if needed.

What are the Requirements for Self-transport by Personal or University Vehicle?

  • If using a university vehicle, personnel transporting the materials must be authorized to use university vehicles and carry a valid driver’s license.
  • Proper containment and packaging must be used (see packaging requirements above).
  • Personnel must be trained and authorized to handle and transport the materials. Contact for more information.
  • If transported by private vehicle, the vehicle used must be for direct and exclusive transport of the sample to the destination (no other stops permitted).

NOTE: Infectious materials meeting the definition of a Category A* substance require certified shipping training through EH&S and are excluded from self-transport using a personal or university vehicle.

*Definition: A Category A substance is a biological material in a form capable of causing permanent disability or life threatening or fatal disease in otherwise healthy humans or animals.

Are There Other Self-Transport Other Restrictions?

Yes. CAUTION: DO NOT transport biomaterials by public tram, shuttle, or taxi.

What if the Samples Must Be Kept Cold or Frozen Samples

  • Use cold packs or wet ice for temperature control during short-term transfers:
    • Place wet ice in a sealed plastic bag or leak-proof container to prevent water leakage.
  • Use special diagnostic shipping containers for frozen samples to maintain low temperature without the use of dry ice. If dry ice must be used, personnel must follow Department of Transportation (DOT) specifications for packaging in an insulated, gas-venting container:
    • Place the dry ice outside of the secondary container inside an insulated cooler or similar gas-venting container.
    • Do not place dry ice in a closed, non-venting container to avoid explosion or injury.
    • Label the outside package with a “dry ice” label.

What are the requirements for receipt of biological materials?

Laboratories receiving biological materials must have prior approval with the Institutional Biosafety Committee (IBC) for transfer, storage, and work with these materials.
