Compressed Gas Cylinders

Purpose and Applicability

The guidance document below provides information on handling compressed gases, including basic compressed gas classification and hazardous properties, and safety guidance on storage, handling and use, transportation and relocation, and disposal of cylinders.

This guidance is applicable to all research and teaching laboratories and non-laboratory areas (facility management, machine shops, studio arts, etc.), where compressed gas cylinders and refrigerated liquefied gases are stored and used. This document meets the Hazard Communication Standard 2012 and GHS classification and labeling criteria. 

While this guidance document describes basic prudent safety practices for handling compressed gases in research labs, the principal investigator (PI) or the lab manager is responsible for developing and implementing standard operating procedures (SOPs) for the purchase, storage, and safe handling of compressed gases that are specific to the PI’s research.
