Hot Work Safety

Hot Work (Welding, Cutting and Brazing)

Hot work operations use an open flame or generate sparks, such as cutting, welding, brazing, soldering, grinding, thermal spraying, thawing pipe, and installation of torch-applied roof systems. The majority of indoor campus hot work takes place in EHS approved designated locations. If you are performing hot work in an undesignated location, you must apply for a hot work permit using the Facilities Management Archibus Work Order System.
