This chapter discusses the major routes of exposure to chemical substances during laboratory work, and several safe handling practices that can minimize your risk while working with chemical substances. The last section lists practices for the safe use of hydrofluoric acid.

This document establishes a procedure for the safe handling and use of streptozotocin, commonly known as STZ (CAS# 18883-66-4), in the university Division of Comparative Medicine (DCM) large animal facilities.

This chapter supplements previous chapters by giving specific extra precautions, postings, training, and protective equipment necessary when working with substances that are highly toxic and/or select carcinogens. The appendices at the end of the chapter are a thorough (but not exhaustive) list of substances that might be present in your lab that are highly toxic and/or carcinogenic.

The purpose of this policy is to establish minimum standards for lab researchers that utilize dangerous gases. These standards will reduce the likelihood of a dangerous gas release and ensure the safety of laboratory researchers, building occupants and emergency responders.
