UNIVERSITIES

Compressed gases—most commonly argon, nitrogen, and oxygen—are widely used across university laboratories. For instance, nitrogen may be used in a cryo chamber as part of sports medicine or physical therapy on campus. While these gases are safe when properly stored, improper handling or usage can cause an explosion.

Compressed gases pose a particular risk at universities, where students, faculty, maintenance workers, and other personnel may use them. All of these people must understand the risks posed by these gases. For more information on laboratory safety, see NIH -Protocol for Use and Maintenance of Oxygen Monitoring Devices 2021.

Gas can leak out if a gas cylinder is improperly stored or a tank becomes damaged in transit. Cylinders are pressurized, so improper handling can cause them to dent, making them more vulnerable to explosion.

To protect the safety of all on campus, universities should invest in oxygen monitors wherever compressed gases are stored or used. These monitors continually check the levels of oxygen in the air to alert individuals to a gas leak. Since nitrogen and argon are colorless and odorless, there is no other way to spot a leak. PureAire’s oxygen monitors include a robust zirconium sensor capable of lasting 10 years with no maintenance. Find out more.
