Transportation or Shipping of Hazardous Materials

This page outlines requirements and provides guidance for transporting or shipping hazardous materials on, between, and off Stanford campuses. This guidance also applies to transporting or shipping hazardous materials off a Stanford campus to another institution’s facilities. 

Any time there is a spill during transportation, contact EH&S immediately by calling (650) 725-9999. For radiological material spills, contact EH&S Health Physics immediately by calling (650) 723-3201.

If you need training or assistance in preparing to ship any hazardous material from Stanford, please contact EH&S by calling (650) 723-5069 to consult with a certified hazardous materials shipper. EH&S staff are available and ready to help prepare any hazardous material for shipment.

For Guidance on Laboratory Moves, refer to the Laboratory Deactivation and Move Guidelines Resource.

Transportation of Hazardous Materials ON Stanford Campus (including hand carrying or transporting on a cart)
  1. Transport of hazardous materials using bicycles, scooters, ride shares, public transportation, the Marguerite shuttle bus system, or other modes of public transit is strictly prohibited. See Transportation of Hazardous Materials In Between Stanford Campuses (below) for how to ship by vehicle on campus.


    Biological Materials
      • Primary containers must have a positive closure mechanism. 
      • Proper secondary containment (leak-proof, hard-walled, and have tight fitting covers). Styrofoam is not permitted as secondary containment. Decontaminate the external surface of the container prior to removing it from the lab. 
      • All containers must be labeled with a biohazard sticker or label (on all four sides and on the lid), biosafety level, and laboratory contact information.
      • Wear proper PPE: lab coat, safety glasses, gloves in addition to proper street clothing
        • Take two gloves with you and wear a glove on the hand touching the container, the other hand should be glove free to open doors and touch elevator buttons. Take extra gloves with you to handle any unexpected issues such as leaks or spills. 
      • Risk Group 3 agents require tertiary containment.
      • If the container spills, immediately contact EH&S 650-725-9999.

    Chemicals / Hazardous Materials
      • Primary containers must have a positive closure mechanism. 
      • Use appropriate safety carriers (a bottle carrier or other secondary containment) when transporting chemicals, either inside or outside of the building.
      • Incompatible materials shall not be transported in the same secondary containment.
      • Recommend using a cart to transport chemicals of one gallon or greater.
      • Chemicals must be clearly labeled with the name of the material, its hazards, and laboratory contact information.
      • Wear proper PPE: lab coat, safety glasses in addition to proper street clothing. 
        • Take two gloves with you and wear a glove on the hand touching the container or secondary containment, the other hand should be glove free to open doors and touch elevator buttons. Take extra gloves with you to handle any unexpected issues, such as leaks or spills. 
      • Alternatives and Safety Measures for 4-Liter Chemical Bottles 
      • Do not take stairways when transporting hazardous materials. Use the elevators.
      • DO NOT leave hazardous materials unattended. Hazardous materials shall be properly stored when delivered.
      • If the container spills, immediately contact EH&S (650) 725-9999. 
      • Note: Hazardous waste is not allowed to be transported from the point of generation. 

    Gas Cylinders
      • Move cylinders with a gas cart with chains only. Do not roll cylinders. 
      • Push, don’t pull, gas cylinder carts. Pulling heavy loads may result in ergonomic injuries.
      • PPE varies based on location and contents of the cylinder. Wear a lab coat and safety glasses in case the cylinder over pressurizes. Gloves may be required for some gases (e.g. corrosives) in addition to proper street clothing.
      • When moving a cylinder, the cap must always be on. 
      • Do not ride on the elevator with a cylinder; if the cylinder begins unexpectedly venting while on the elevator, you would be trapped in an unventilated area at risk of asphyxiation. Place the cart in the elevator with a sign that says “Do not get on the elevator”. Then, take the stairs and meet the cart on the destination floor or have a colleague receive it on the destination floor.

    Cryogenic Materials
      • Use properly insulated containers when transporting cryogenic materials by hand.
      • Do not seal containers with cryogenic materials inside. Pressure will build in sealed containers.
      • Wear proper PPE: Wear a lab coat, safety glasses, cryogen gloves, and appropriate street attire when transporting cryogenic materials, either by hand or in cryogenic liquid tanks (aka dewars).
      • Push, don’t pull, cryogenic liquid tanks. Pulling heavy loads may result in ergonomic injuries.
      • Do not ride on the elevator when transporting cryogenic materials either by hand or in cryogenic liquid tanks/dewars. 
        • Transporting by hand: Take the stairs. 
        • Transporting cryogenic liquid tanks/dewars: Place the tank in the elevator with a sign that says  “Do not get on the elevator”. Then, take the stairs and meet the cart on the destination floor or have a colleague receive it on the destination floor.

    Radioactive Materials
      • All work with radioactive materials, including transportation, must be performed under a Controlled Radiation Authorization (CRA).
      • Protocols involving the transportation of radioactive materials must be reviewed and approved by the CRA PI and EH&S Health Physics.
      • Must have appropriate radioactive material training before handling radioactive material.
      • Wear proper PPE: lab coat, safety glasses, gloves, in addition to proper street clothing and dosimetry, if assigned by Health Physics.
        • Take two gloves with you and wear a glove on the hand touching the container, the other hand should be glove free to open doors and touch elevator buttons. Take extra gloves with you to handle any unexpected issues, such as leaks or spills. 
      • Proper secondary containment (leak-proof and have tight fitting covers).
      • Survey the contents of the container prior to transport.
      • All containers must be labeled with isotope, activity, and date.
      • If the container drops or spills, immediately contact EH&S Health Physics 650-723-3201. Do not leave the scene.

    Transport of hazardous materials using bicycles, scooters, ride shares, public transportation, or the Marguerite shuttle bus system, or other modes of public transit is strictly prohibited


    Biological Materials & Chemicals / Hazardous Materials
      • Must follow the Materials of Trade Department of Transportation (DOT) exemption to transport biological materials or chemicals on public roads. 
      • Hazardous materials must not be transported in the passenger compartment of the vehicle. They must be kept in the trunk of a passenger vehicle or the bed of a truck. Driver must be informed that the material is being transported. 
      • Materials must be in the manufacturer’s original packaging or the sample needs to be in a primary container with a positive closure mechanism.
        • Primary container must be leak tight, securely closed and in combination packaging (container inside of another container with absorbent materials) – request a 5 gallon pail from EH&S Safety Store as an outer container.
        • Containers must be properly closed, secured against movement and protected against damage
        • The outer container must be labeled with the chemical name or the infectious agent and name of responsible person in case of an accident
