A superconducting magnet uses two types of cryogens (liquid helium and liquid nitrogen). Cryogenic liquids can be handled easily and safely, provided certain precautions are followed as outlined in these instructions.
Use the Exposure Response Poster as a guide for responding to a biological, chemical or radiological exposure.
Post in your lab alongside the Spill Response Poster.
Compressed and liquefied gases are routinely used in laboratories, shops and various other operations at the University. Compressed gas is a generic term used for describing compressed gases, liquefied compressed gases, refrigerated liquefied gases (cryogenic fluids) and dissolved gases.

Safety Data Sheets (SDSs) are documents that describe the physical and health hazards of chemicals or chemical-containing products and must be readily accessible to employees during all work shifts when these products are present in the work environment.
EH&S maintains a centralized library of SDSs in the online MyChem database for your use. SDSs are added to the central collection as employees inventory their chemicals in MyChem.
Elemental or metallic mercury is a potent neurotoxin, even with small exposures. Avoid exposure by replacing broken thermometers and lamps, and use a spill kit to manage a spill clean-up.
Health effects of mercury
Mercury is a liquid at room temperature and readily evaporates into the air. People can be exposed if instruments or equipment containing mercury break and release mercury-containing dust, liquid or vapor. Health effects can include central nervous system disorders, reproductive effects and kidney damage.
The U.S. Department of Transportation (US DOT) requires you be trained and certified before shipping hazardous materials. Even if someone else handles your shipment for you, you are responsible for packaging and labeling hazardous materials correctly, and providing the required documentation. Fines for non-compliance and potential legal action can occur if you are found to have willfully ignored hazardous materials shipping regulations.
Notes:
The Chemical Exchange program allows MyChem users to share unused chemical inventory to save money and reduce waste.
The Chemical Exchange allows you to search for available chemicals or chemical products in MyChem inventories, and save money and reduce waste. You can flag chemicals in your own inventory to share with others at the University. Hundreds of chemicals are waiting to be exchanged.
The UW is committed to providing a safe and healthy work environment for all employees, students and visitors. Individuals who work with or near hazardous substances need to be aware of the identity, potential physical and health hazards, and the safe work practices that can minimize exposure.
Supervisors (including PIs) are required to train personnel on the hazards of the chemicals used in University workplaces, regardless of location.
Be prepared with proper training, cleanup supplies and personal protective equipment to manage spills easily and safely.
If you work with chemicals, you will probably have a chemical spill at some point. Your safety, and the safety of others, depends on your assessment and response.
To assess whether you and your fellow researchers are prepared to manage a chemical spill, consider these questions:
UW personnel who use chemicals or chemical-containing products at any UW owned or leased facility are required to maintain chemical inventories in MyChem, the UW’s chemical tracking system.
