Protocol for Use and Maintenance of Oxygen Monitoring …

ors.od.nih.gov

Compressed gases and cryogenic liquids (mainly nitrogen, helium, and carbon dioxide) may be used in laboratories and other locations for various lab applications and work procedures. Nitrogen and helium are the most commonly used compressed gases; primarily for their freezing properties and use in storing laboratory samples and/or components.

Never use compressed helium gas from a cylinder without a proper regulator. Overpressure can cause serious injury if the system equipment ruptures. During operation, some surfaces under the compressor’s cover become hot. Allow the compressor to cool for 1/2 hour after shutdown before removing the cover for maintenance.
