Tufts Environmental Health and Safety (TEHS) contracts with an outside vendor to assist with the semi-annual high hazard audit of chemicals. The audit entails visiting each wet lab to review chemical stock. During this review, chemicals that are or could become unstable will be identified and communicated to the lab. Common examples are old ether and tetrahydrofuran.
The purpose of this assessment is to identify any potentially energetic materials that may pose a safety risk to laboratory personnel, and dispose of them if necessary. This assessment also includes an inspection of storage practices of more common hazardous chemicals, and cites incidences of improper chemical storage that could also pose a safety risk for laboratory personnel
