Frequent Questions

What is considered cryogenic conditions?

The Tier II Hazardous Chemical Inventory form, used to meet annual EPCRA §312 reporting requirements, requires facility owners or operators to note whether reported hazardous chemicals are present at, above, or below ambient temperature.  For temperatures below ambient, the form distinguishes between “less than ambient temperature but not cryogenic” and “cryogenic conditions.”  What is considered cryogenic conditions?  


Some gases are stored under “cryogenic conditions,” which means that they are stored at very low temperatures (-130 degrees Fahrenheit or less).  Examples of gases that may be stored this way include air, argon, carbon monoxide, ethylene, fluorine, helium, hydrogen, methane, nitrogen, and oxygen.
