Hot Work

• Goals and Objectives
• At the end of this program you will
• - Recognize work that requires the use of
• Hot Work Permits.
• - Be familiar with and able to implement the
  PSU Hot
• Work Permit Process.

3
What is Hot Work?

• Definition
• Hot Work is any work using open flames or sources
  of heat that could ignite materials in the work
  area.

4
Hot Work

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

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.

Is Hot Work Necessary??

• Question to Ask
• Can the job be avoided or is there a safer
  way?

• Before beginning any hot work, ask yourself if
  the work can be done a safer way. Hot work is
  potentially very hazardous and should be avoided
  if not absolutely necessary.

8
Work that may not require the use of a hot work
permit includes

• Areas that are maintained and identified as
• - Welding Shops
• - Maintenance shops with designated
• areas for hot work activities
• Work on equipment (ex. Farm Implements) occurring
  in areas outside of buildings where the potential
  for fire development is minimal.

9
Starting the Process
Procedures Before beginning hot work a hot work
permit must be completed. Permits can be
obtained from your supervisor or the Penn State
Environmental Health and Safety Web Page at
www.ehs.psu.edu

Hot Work Safety Precautions

• Required Safety Precautions
• ? Fire suppression sprinklers, fire hoses or
  fire extinguishers are available and operable.
• ? Hot work equipment is operable and in good
  repair.
• ? Smoke / fire detectors in the immediate area of

  responsibility to verify that all necessary
  precautions have been taken at the worksite.

12
Safety Precautions (contd)

• Are Fire Suppression Sprinklers in service ?

• 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 EHS Fire Protection Engineer. If
  a sprinkler system needs to be taken out of
  service, Campus specific procedures must be
  followed.

13
Safety Precautions (contd)

• Is cutting and welding equipment in good repair ?

• Gas hoses, backflow preventers, fire resistive
  tarpaulins, curtains and other cutting and
  welding equipment must be maintained in good
  repair.

14
Safety Precautions (contd)Anything that 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
