4. Hot Work Examples of hot work are: • welding • burning • brazing • propane soldering • oxyacetylene cutting • grinding ferrous metals • torch applied roofing • heat gun

5. Hot Work Why Hot Work Permits? • Every year fires related to hot work activities occur causing significant property damage and business interruption. Many of these fires could have been prevented if employees and contractors had used appropriate fire prevention measures while conducting hot work. • During a recent 5 year period FM Global reported that after Arson and Housekeeping, Hot Work was the third leading cause of fires in FM insured properties with an average fire loss totalling $1.4 million dollars per incident. • Penn State University requires the use of the Hot Work Permit system as a primary tool for preventing the outbreak of fire due hot work operations.

The employee performing the Hot Work has the responsibility to verify that all necessary precautions have been taken at the worksite.

12. Safety Precautions (cont’d) Welding and other hot work have been found to be a leading cause of fires in University settings. Sprinkler systems should remain in service in the hot work area, unless specifically approved by the EH&S Fire Protection Engineer. If a sprinkler system needs to be taken out of service, Campus specific procedures must be followed. Are Fire Suppression Sprinklers in service ?

13. Safety Precautions (cont’d) • Gas hoses, backflow preventers, fire resistive tarpaulins, curtains and other cutting and welding equipment must be maintained in good repair. Is cutting and welding equipment in good repair ?

14. Safety Precautions (cont’d)Anythingthat can burn must be removed or protected from the immediate work area. Requirements within 35 feet:  Area within 35 feet of the work area has been properly swept to remove any combustible debris.  Flammable and ignitable materials and debris have been moved at least 35 feet from the hot work area or covered and protected with fire resistant materials.  Cracks or holes in floors, walls and ceilings (including ductwork) are covered or plugged.  Combustible floors covered with fire-resistive material Requirements within 50 feet:  Explosives, compressed gas cylinders or stored fuel have been moved at least 50 feet from the hot work area or have been protected from the hot work. Work on walls or Ceilings  Construction is noncombustible and has no combustible covering or insulation.  Areas adjacent to walls being worked on are checked for combustibles and any combustibles are either removed or protected.

15. Fire Watch • Fire Watch Personnel must be trained to use fire extinguishers or other fire extinguishing equipment that is present. • Fire Watch Personnel must be aware of how to report emergencies and to activate building fire alarm systems. • Fire Watch Personnel must be identified and their qualifications verified prior to commencing hot work.
