Liquid Nitrogen and Gas Cylinders


There are no expected supplier and/or delivery disruptions for liquid nitrogen and gas cylinders.

During the COVID19 Pandemic, laboratories are responsible for the continued management of their own liquid nitrogen and gas cylinder needs.

The FHSSO does not handle liquid nitrogen or gas cylinders.

Liquid nitrogen and gas cylinders are two research consumables that require cyclical pickup and delivery. The process for each is managed by a number of different groups, and the contacts within these groups may be different according to the building in which you work. The players in these groups include:

  • supplier
  • laboratory supervisor/workers
  • building security
  • logistics (building or campus)
  • hospital logistics
  • Faculty of Heath Sciences Safety Office (FHSSO)

Those involved in direction and handling of liquid nitrogen and gas cylinders must be familiar with their responsibilities under RMM504 - Compressed and Liquefied Gases Safety Program in addition to completion of Gas Cylinder (GASCYL) training on Mosaic.

For the management and delivery of LN2 and gas cylinders on campus, please contact EOHSS.

Liquid Nitrogen Delivery

Dewar Registration

As of May 2013, Facility Services manages all administrative activities related to the filling, replenishment and billing of tanks/dewars containing and transporting liquid and gaseous nitrogen. Liquid nitrogen transport dewars are to be registered with the FHS Safety Office. This does not include biological storage tanks, only those tanks which are transported in and out of the lab for filling. Please contact the FHS Safety Office for the forms required to register your dewar. All queries related to liquid nitrogen billing are to be directed to Anne Symons.

You will receive a vinyl sticker with the number on it. Note: during this time if you are assigned a number, you are responsible for labeling the dewar, as our office is working remotely during the pandemic and cannot physically provide stickers.

Gas Cylinder Delivery

Cylinder Exchange

Cylinder exchange involves calling to arrange for pickup and drop off of your size and type of gas cylinder. Unattended gas cylinders in hallways are prohibited. All gas cylinders are to be secured to prevent tipping and caps are to be replaced when the cylinder is not in use.

The FHSSO does not faciliate sales, provide service or negotatie any service agreements for gas cylinders. This agreement is solely through HHS and issuees related to gas cylinder service are to be directed to Mike Mans.
