Chemical Safety

Your right-to-know

Compressed gas safety: All compressed gasses can be dangerous, even those that are not flammable or toxic. Inert gasses act as asphyxiants, and a ruptured cylinder can cause physical damage. Cryogenic liquids pose the same asphyxiation hazard as compressed gasses, but also introduce the possibility of severe cold burns.

For information on disposing of chemical, biological, radioactive, or other hazardous waste, see our waste page.


There are 25 OSHA regulated chemicals, including formaldehyde, benzene, methylene chloride, and vinyl chloride. You must report use of these chemicals to EHS.

See the chemical storage and compatibility page for information on storing acids, bases, solvents, oxidizers, and other toxic or dangerous chemicals.

A Material Safety Data Sheet (MSDS) is required for any newly-created chemicals especially if the material will be sent to another institution.
