Laser cutting: Nitrogen is typically used in the steel industry when cutting any type of metals.Nitrogen gas is also used in the packaging of medical supplies to keep them sterile and clean which helps to preserve the product. Nitrogen is essentially used as a blanket gas, purging gas and a gas for when transporting these oxygen sensitive materials. Pharmaceuticals: APIs, inactive ingredients and other chemicals must be kept in an inert atmosphere to prevent oxidation.The same principles are applied to beverage packaging as they do with dried foods, where nitrogen is used to prevent oxidization in juice, wine, and beer. There will be no moisture as nitrogen is a dry gas which keeps products such as chips crisp. Food packaging: It is a common practice to use compressed nitrogen to displace oxygen to extend shelf life of food.Nitrogen gas will reduce the amount of oxygen in the air so that the solder remains strong. Electronics: When assembling electronics, nitrogen gas is used in soldering to form a connection between two components.Nitrogen plays a significant role within all these industries and can be used for many different applications. Nitrogen is used in a variety of industries including electronic manufacturing, food and beverage, pharmaceutical, steel, and many more. The training covers the hazards associated with liquid nitrogen and the best practices for using, moving, and storing liquid nitrogen.CAPS Australia breaks down the role and benefits of on-site nitrogen generation in manufacturing. EH&S recommends enrolling in the EH&S Liquid Nitrogen Safety online training.

If an UW end-user decides to assume the responsibility for ordering and storing LN2 Dewars for the purpose of filling smaller Dewars and vessels for cryo storage, please contact EH&S at for assistance in evaluating the room or area for cryogen storage and use to ensure safety and compliance with local fire code requirements.ĮH&S recommends all UW personnel who dispense LN2 into a Dewar and/or connect/disconnect an LN2 Dewar to a Cryo-freezer should read the equipment-specific operations manual and understand how the equipment works and follow the manufacturer’s instructions.Īll UW personnel who work with LN2 are required to be trained on the hazards and preventive measures when working with cryogens.
Har Dang, Life Science Specialist personnel will have to assume these responsibilities or utilize Praxair as a supplier, who continues to offer this service upon request. – An Air Liquide Company Seattle, WA |Ĭustomer Service 20 | Mobile (206)-930-5703 Please contact Airgas Customer service or email the customer service representative at:Īirgas, Inc. Connect or disconnect LN2 sources to cryo-freezers where human biological samples are stored.Īirgas will continue to connect/disconnect LN2 Dewars to cryo-freezers that contain non-human biological samples with a signed Cryo Storage Product Supply Agreement.Dispense LN2 into Dewars and vessels containing any biological samples, and.and Praxair (aka Linde Welding Gas and Equipment Center) for cryogenic storage used to preserve biological samples.Īirgas recently notified the University that as of January 1, 2022, Airgas staff will no longer perform the following services: UW personnel commonly order liquid nitrogen (LN2) from suppliers such as Airgas Inc. Hazardous Energy Control - Lockout/Tagout.Asbestos and Other Regulated Building Materials.UW Research & Training Building Remediation.Use of Radiation in Human Subjects Research.Radiation Detection Instrument Calibration.Fire Code Hazardous Materials (HazMat) Compliance.Building Emergency Procedures and Resources.Designated Areas for Smoking and Vaping.Fume Hoods: Use, Inspection and Maintenance.
