Cryogen Training


Training of Personnel Using Cryogenic Fluids

All personnel working with cryogenic fluids must be thoroughly familiar with the hazards. Employees who have not worked with cryogenic fluids and systems must be trained on the job by experienced employees until thoroughly familiar with safe methods of operation. A buddy system is recommended when working with or around cryogenic liquids.

The safety training should address:

• The physical, chemical and physiological hazards associated with cryogenic fluids

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.

In An Emergency...   

Get yourself to a safe location and call UVM Police by dialing 911 from a UVM office phone or land line. You can also reach UVM Police by dialing 656-FIRE (3473).

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.


Emergency Equipment

Emergency Equipment

Emergency equipment must be maintained, inspected and tested to maintain proper working order as part of preparation and planning for an emergency. In the event of an emergency, properly functioning emergency equipment can help minimize both personal injury and property damage. Types of emergency equipment found in laboratories include eyewash stations, safety showers and fire extinguishers.

Emergency Prevention

Laboratory Emergency Prevention

Adhering to UVM's Environmental Safety Values will help prevent emergencies:

1. Safety: Ours and yours is the top priority during hazardous work.

2. Partnership: Government regulations were developed in response to actual situations that endangered the health of people and are designed to protect the health of the community and the environment. These are the second priority for UVM activities.
