Laboratory Safety Unit

Liquid Nitrogen Signage

Since liquid nitrogen poses unique safety hazards, the Laboratory Safety Unit requires areas having several tanks to have an oxygen sensor mounted in the room where the tanks are located. The sensor will alert personnel of an accidental release of the gas resulting in an oxygen-deficient environment.

The sign developed by Lab Safety lists the personal protective equipment (PPE) required for the safe handling of liquid nitrogen, the hazards associated with it, and the emergency response if the oxygen sensor alarm sounds. This sign needs to have contact information listed and must be printed in COLOR and posted near the location of the liquid nitrogen where it can be easily seen.

The placement of the sensor needs to be in an area where it will detect an accidental release of the liquid nitrogen but not alarm each time the tank vents. For questions as to the placement of the sensor or other concerns, please contact the Laboratory Safety Unit at 275-3241.
