Penn State University Hot Work Permits

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.

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.

Hot Work

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

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 totaling $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??

• 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.

Question to Ask: Can the job be avoided or is

there a safer way?

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 (e.g. Farm Implements) occurring in areas outside of buildings where the potential for fire development is minimal.

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

Starting the Process

Hot Work Permit WARNING!

HOT WORK IN PROGRESS WATCH FOR FIRE!

In case of FIRE call 911 University Park Emergency Numbers: PSU Police 863-1111 EHS 865-6391 OPP Service Desk 865-4731

Permits are issued for the specific job being done, and for a specific time period. The time period is usually for the working shift, but may never exceed twenty-four hours.

Completed Permits need to be displayed in the hot work area.

Hot Work Safety PrecautionsRequired 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 the hot work have been temporarily disabled until the hot work is complete. Building occupants have been protected or isolated from the hot work area. Drums, barrels and tanks have been cleaned and purged of flammables and toxics, all tank feeds are closed, and the tank is vented.

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

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 ?

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 ?

Safety Precautions (cont’d)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 have 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 have been covered with fire-resistive materialRequirements 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.

Fire Watch

• Fire Watch Personnel must be trained to use fire extinguishers and 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.

Fire Watch Personnel's main responsibility is to monitor the area for the possible development of fire from the hot work. Other job tasks can be performed as long as they are able to adequately monitor the area for potential fire.

Fire Watch Fire watch will be provided during and for at least 30 minutes after hot work has

been completed and during any coffee or lunch breaks.

Fire watch is supplied with suitable extinguishers, or charged small hose. Fire watch is trained in use of this equipment and in sounding alarm.

Fire Watch (cont’d)

Should other precautions fail, trained personnel will be needed with firefighting equipment to extinguish any fires which start. Personnel andequipment must be readily available before hot work is started.

Fire Watch required during Hot Work and a minimum of 30minutes following completion of work.Yes ____ No ____ Name: ___________________________

A fire watch is needed for all hot work activities unless the hotwork area has no fire hazards or combustible exposures. The firewatch must have fire-extinguishing equipment readily availableand be trained in its use. They must also be familiar with theprocedures for sounding an alarm in the event of a fire. The firewatch will watch for fires in the exposed areas and areresponsible for extinguishing spot fires and communicatingalarms immediately.The fire watch may be assigned other work duties while in the hotwork area, however they need to be vigilant in watching for fires.

Hot Work CompletionWhen work is completed: Inspected work area, and any potentially affected surrounding areas, for fire, fire damage, or potential for

fire. Reactivated smoke / fire detectors that were disabled because of the hot work.I verify that the above location has been examined and the necessary precautions have been taken toprevent the outbreak of fire due to Hot Work.

familiar and trained in Hot Work Procedures.

• Jobs like electric arc welding, brazing, gas soldering, oxygen-acetylene cutting, welding and torch applied roofing work may require the use of a hot work permit.

• Permits are issued for a specific job and for a specific time frame.

• All necessary equipment must be on site and in good working order before work begins.

• A fire watch must be present for the duration of hot work and for at least 30 minutes after work is completed.
