Prior to initiating research, consider whether any materials may be considered hazardous and seek support from Environmental Health & Safety (EH&S). EH&S can help researchers perform risk assessments, find ways to mitigate risks, and identify regulatory requirements. Use of hazardous materials will almost always require training and in some cases will also need to be registered with a local committee for review prior to initiating work. Regulated research materials may require permitting or licensing with regulatory bodies as well as local committee oversight and usually have very specific instructions for waste disposal. Common hazardous and regulated research materials are listed below with the departments on campus that can provide guidance.
