Wall mounted fixed oxygen monitors protect employees in case of a cryogenic gas leak. Oxygen depletion is called a silent killer since there is no warning that the air is oxygen deficient. The Occupational Safety and Health Administration (OSHA) specifies that a hazardous condition may include one where the oxygen concentration is below 19.5% or above 23.5%.

Detecting low oxygen levels revolves around using advanced oxygen sensor technologies. Oxygen depletion meters or monitors utilize zirconium oxide sensors to gauge the oxygen concentration in the environment. These O2 sensors offer real-time measurements and will trigger audible and visual alerts when oxygen levels fall below safe thresholds, alerting personnel to take immediate action.

Industries that commonly use compressed, oxygen depletion gases, such as nitrogen, argon, carbon dioxide, and helium among others, include but not limited to laboratories, MRI and IVF, food and beverage, pharmaceutical, research and development, semiconductor, additive manufacturing, and cryogenic facilities.

According to guidelines put out by the National Institutes of Health (NIH) an oxygen monitoring device shall be installed in any indoor location where compressed gases or cryogenic liquids are stored and/or dispensed in manner that could create the potential for the displacement of oxygen.

Additionally, nitrogen gases or cryogenic liquids shall not be located or dispensed in any indoor location that does not have proper ventilation.

If oxygen levels decrease to an unsafe level, the Monitor will set off audible and visual alarms, alerting personnel to evacuate the area.

Furthermore, the oxygen monitoring device should have alarm and warning levels set according to the OSHA guidelines.
