UW personnel commonly order liquid nitrogen (LN2) from suppliers such as Airgas Inc. and Praxair (aka Linde Welding Gas and Equipment Center) for cryogenic storage used to preserve biological samples.
Airgas recently notified the University that as of January 1, 2022, Airgas staff will no longer perform the following services:
Use and dispensing of flammable liquids presents fire and explosion hazards to facilities and occupants. Proper grounding and bonding limits the potential of static electrical spark during dispensing.
Keeping your safety documents up to date and easily accessible are key for staying safe.
Chemical Hygiene Plans (CHPs) include lab-specific information and relevant documents in addition to the UW Laboratory Safety Manual (LSM) provided by EH&S. This information must be reviewed at least annually and is necessary to fulfill WAC 296-828-20005. Read the Creatiing Electronic Chemical Hygiene Plans focus sheet for more information and instructions on creating one for your lab.
EH&S launched a new Chemical Container Labels webpage where UW employees can learn about the requirements for labeling chemical containers of various types and download a number of customizable chemical label templates.
