Hot Work Procedures

A local fire code permit, which may be obtained from the local fire official, is required for all cutting and welding operations conducted in the Municipality of Princeton.

While Princeton University does not currently require hot work permits to conduct hot work on campus, the Office of Environmental Health and Safety (EHS) in conjunction with the Office of the Fire Marshal require that the following considerations be given prior to beginning any hot work on campus.
