Jeffords Hall


Storage Limit for Flammable Liquids 

There is a 5-gallon limit on the storage of flammable liquids in each Jeffords building laboratory. This limit is based on fire code restrictions for a building of this type of construction.


Neutralization Tank

Delehanty is one of the few buildings on campus with a neutralization tank to dispose of weak acid solutions.  UVM Environmental Health and Safety and the UVM Geology Department have designed a specific Sink Disposal Agreement, approved by the City of Burlington. Contact us for specifics as to which acids are appropriate for disposal in this system. Only lab sinks with blue plumbing below the sink lead to the neutralization tank on the first floor. No hazardous waste other than weak acids may be poured down these drains in Delehanty.

Biowaste Management


Biohazardous and infectious (or potentially infectious) agents are routinely handled and manipulated in biomedical and animal laboratories. Biohazards include human samples and tissue cultures, bacteria, viruses, prions, parasites, toxins, recombinant DNA (rDNA) - which is used in expression vectors such as plasmids, infected or transfected/transduced cells, infected human or animal tissues, transgenic animals, and any material contaminated with a biohazardous agent.

Biological Safety Cabinet Training

BSC training is compulsory for researchers working in laboratories with a minimum biosafety level BSL2. Online training is available at:  Please, log in with your net ID and password and take the online training "Safe Use of Biosafety Cabinets".

BSC Certification Failure

If your cabinet has failed the certification, it means that it is not performing as it should. This may compromise the quality of your work (e.g, contaminated cells) or expose you and the environment to aerosols from infectious agents (e.g., exhaust filter damaged). You should not resume work within the BSC until it is repaired and passes the certification. Contact Environmental Safety at if you have any question or concern.

Contamination Problems in the BSC

Most BSCs (except Class I) are equipped with HEPA filters that supply clean air to the working area. If the supply filter is damaged or leaks, dirty air may be supplied to the BSC, contaminating the area. Schedule a certification with a specialized technician to check the performance of your BSC.

Biological Safety Cabinets and Clean Benches

While all types of biological safety cabinets protect personnel and the environment from exposure to contaminants within the cabinet, clean benches do not. In clean benches, contaminated air is directly blown towards the user and surrounding environment. For this purpose, clean benches should only be used to conduct work that requires sterile conditions (such as preparing sterile solutions) but that does not involve manipulation of biohazards, chemical hazards or radioactivity.
