Hot Work

A Philadelphia Department of Licenses & Inspections and Jefferson hot work permit is required when burning, welding, torch cutting, grinding where sparks are produced, soldering or brazing in Jefferson owned buildings.

The Department of Environmental Health & Safety has the responsibility for issuing hot work permits, assisting departments in developing appropriate hot work safety plans, providing technical guidance and assisting with employee training where applicable.

Special Precautions to follow:

  1. Prior authorization from:
    1. Thomas Jefferson University Fire Marshal.
    2. Notify Control Room (TJUH/TJU) at 215-955-1418 of start and end of hot work.
  2. Ensure that the area has been made safe by the removal of all combustibles from the ignition sources.
  3. Determine that fire protection and extinguishing equipment are properly located and readily available.
  4. Provision of a fire watch.
  5. Protection of walls and floors (e.g. fire blanket).

Hot Work Permit

Before hot work operations begin, a completed hot work permit prepared by the Jefferson Fire Marshal is required.  Based on local conditions, the Fire Marshal must determine the length of the period for which the hot work permit is valid. 

Work Closeout

  • A fire watch shall be maintained for at least 1 hour after completion of hot work operations in order to detect and extinguish smoldering fires.
  • The Fire Marshal shall inspect the job site on the same day before or following completion of hot work.  A close out date will be provided on the permit.
  • The completed Hot Work Permit shall be retained 3 years following completion of the project.
