Hot Work Program

The Iowa State University Hot Work Permit Program was developed in accordance with OSHA regulations and NFPA standards with the goal of preventing hot work fires.  All hot work must be conducted in Designated Hot Work Areas or under the Hot Work Permit Program. 

Designated Hot Work Area

A Designated Hot Work Area is a permanent location designed for hot work. For a space to be classified as a Designated Hot Work Area, it must meet the following requirements:

  1. It must be of noncombustible, fire-resistive construction, essentially free of combustible and flammable contents.

  2. It must be suitably segregated from adjacent areas.

  3. It must be equipped with an appropriate fire extinguisher.

  4. It must be inspected and approved by EH&S. 

Hot Work Permit

Before hot work can be performed outside of designated hot work areas, a Hot Work Permit must first be obtained. Hot Work Permits can be obtained from Permit Authorizing Individuals who have been designated as such by department supervisors.  All Iowa State University employees who perform or supervise hot work must complete Hot Work Permit Training

Outside contractors working on the Iowa State University campus are required to have hot work safety procedures as a part of their project safety programs. Contractors working on capital projects at Iowa State University are required to follow the hot work guidelines outlined in project specifications.
