O2 Oxygen Sensors

The FDNY Code requires that O2 Oxygen Sensors be installed in areas where more than 60 gallons of cryogenics are stored, in use, or dispensed. In areas where more than 60 gallons are identified, EH&S asks that labs assess the way cryogenics are managed to minimize the purchase of required O2 sensor installations.

The following are suggested:

* Increase cryogenic delivery frequency,
* Store cryogenics in one area (one sensor), OR
* Distribute cryogenic storage among multiple laboratory rooms.

If an existing laboratory does increases the use of cryogenics that exceed the threshold of 60 gallons, thus requiring a 02 sensor, please contact: fire-life@columbia.edu for information about obtaining an O2 sensor.
