Dispensing Cryogens

A liquid nitrogen burn causes the death of living tissue by extreme cold. 

Watch a video about how to fill a hand dewar with liquid nitrogen safely.

Safe Dispensing of Liquid Nitrogen

1. Under no circumstances should you leave the area while filling a dewar.

2. Put on protective clothing.

Handling Cryogens

Handling Cryogens Safely

The hazards associated with the handling of cryogenic fluids include cold contact burns and freezing. This happens when skin comes in contact with cold liquid, gas or surface.


Laboratory Emergency Response

Emergencies are situations where there is a threat of a fire, life-threatening situations, or unexplained symptoms associated with an odor.

Chemical Safety

Laboratory work often involves the use of hazardous chemicals.  Before using a chemical, lab workers must become informed about chemical hazards in addition to their safe handling, storage, and disposal.  Information about chemical hazards can be found below.



Biohazardous Waste Management

In order to comply with state regulations, UVM requires that all solid biowaste be incinerated by our biowaste contractor. For an overview of this program, take the Biowaste Management Procedures on line course

Please forward any questions you have on this subject to Jeff LaBossiere, the Biosafety Program Coordinator, at

Mercury Thermometer Exchange

Program Highlights

We are working to get elemental mercury out of UVM laboratories as well as the environment. You can help us by swapping your mercury thermometers for non-mercury thermometers. Contact us at and let us know what you need for replacement. The choices are:

Temperature range: -20 to 110 degrees Celsius or -10 to 260 degrees Celsius

Partial or total immersion:

Infectious Agents

Research or teaching activities involving infectious agents must have prior approval by the Institutional Biosafety Committee. Laboratory workers must follow the requirements specified in the Biosafety in Microbiological and Biomedical Laboratories as the minimum containment required for this work. In specific instances, containment requirements may be subject to modification by the IBC or the Biosafety Program Coordinator.

Safety Data Sheet Information

Looking for Safety Data Sheets (SDS)?

We recommend that you first try the Canadian Centre for Occupational Health and Safety. UVM has a site license for access to this database, which includes over 100,000 SDS's, updated quarterly.

Train and Inform Lab Personnel

When Is Safety Training required?

Training is required to ensure that all lab employees are informed about the hazards with which they work. This may including  chemical, biological, radiological and physical hazards as well as waste management procedu
