HOT WORK POLICY

Purpose

In order to minimize the risk of injury and damage caused by any temporary operation involving open flames or producing heat and/or sparks, including but not limited to welding, burning, brazing, and propane soldering (“hot work”), West Point Public Schools (WPPS) requires that all employees and other workers engaged in hot work on district property or under the control of the district (collectively, “workers”) shall follow this Hot Work Policy.

 

Hot Work Supervisor

Designation.  The Operations and Maintenance Director or designee will serve as the district’s Hot Work Supervisor.

 

Responsibilities.  A Hot Work Supervisor shall be responsible for the following:

a.            Issuing and administering hot work permits.

b.            Ensuring that the hot work permit and this policy are understood by all workers performing hot work.

c.            Determining whether a Fire Watcher is required for a hot work project and designate the Fire Watcher.

d.            Advising all outside contractors who will perform hot work on district property of flammable materials or hazardous conditions which are not readily apparent.

e.            Informing all outside contractors who will perform hot work on district property or under control of the district that they must follow all OSHA requirements.

 

Engaging in Hot Work

Engagement.  All workers planning to engage in hot work must:

            a.         understand this Hot Work Policy;

b.         be suitably trained in the safe operation of the equipment used to perform the hot work;

c.         employees of WPPS must obtain a hot work permit as provided herein; and 

d.         know, in reference to the hot work site, the location of the nearest phone, fire protection and extinguishing equipment, and manual fire alarm pull station.

 

Performance.  When performing hot work, all workers must:

a.         use appropriate personal protective equipment including, but not limited to, welding helmets, gloves, jackets, and eyewear.

b.         employees of WPPS must cease hot work and contact the hot work supervisor if conditions under which the hot work permit was issued change. 

 

Fire Watch

Fire Watcher.

a.         A Fire Watcher is a person that shall be on the hot work site when required.

            b.         A Fire Watcher must have fire extinguishing equipment readily available and must be trained in the use of the readily available fire-extinguishing equipment

c.         A Fire Watcher must be familiar with the hot work site and surrounding facilities in order to be able to sound an alarm in the event of a fire

d.         A Fire Watcher must watch for fires in exposed areas, try to extinguish fires only when obviously within the capacity of the equipment available, or otherwise sound the alarm.

 

 

When Required.  Fire Watchers shall be required whenever hot work is performed in a location where:

            a.         more than a minor fire may develop;

            b.         there is appreciable combustible material in building construction or

contents closer than thirty-five (35) feet to the point of operation;

c.            there is appreciable combustible material more than thirty-five (35) feet away but easily ignited by sparks;

d.            there are wall or floor openings within a thirty-five (35) foot radius which expose combustible material in adjacent areas including concealed spaces in walls or floors; or

e.            there are combustible materials that are adjacent to the opposite side of metal partitions, walls, ceilings, or roofs that are likely to be ignited by conduction or radiation.

 

Duration of Fire Watch.  If a Fire Watcher is required, such Fire Watcher must be maintained at the hot work site for at least thirty (30) minutes after completion.

 

Hot Work Permits (WPPS Employees)

Permits.  A separate hot work permit must be issued for each hot work project.

 

Duration.  All hot work permits must specify a time period and shall not, in any case, cover a time period in excess of twenty-four (24) hours. 

 

Class Work.   A hot work permit is NOT required of student work during an approved class.

 

Issuance

Requirements.  In order to issue a hot work permit, the Hot Work Supervisor or designee must determine all of the following:

 

a.         with the exception of emergencies, hot work permits will not be issued the last hour of the day.

b.         that the work site is NOT a “prohibited work area” as defined herein.

c.         that fire protection and extinguishing equipment is maintained in a state of readiness for instant use at the site where the hot work will be performed.

d.         that the hot work equipment is in good and safe operating condition.

e.         that, if required, a Fire Watcher is present at the hot work site.

f.          that, when removal and relocation of flammable and combustible material is not possible as provided above, all flammable and combustible materials are protected with flameproof covers or otherwise shielded with metal or asbestos guards or curtains.

g.         that combustible floors are kept wet, covered with damp sand or protected by fire-resistant shields and that when floors have been wet down, workers operating equipment shall be protected from possible electrical shock.

h.         that openings or cracks in walls, ceilings, roofs, windows, doors, floors, etc. at the work site are covered to prevent heat and sparks from passing to adjacent areas.

i.          that ducts and conveyor systems on or near the work site that might carry sparks to distant combustible and flammable materials are suitably protected or shut down.

j.          that if hot work is done near a metal wall, partition, ceiling, or roof, precautions are taken to prevent ignition of combustible or flammable materials on the other side due to conduction or radiation.

k.         that special precautions have been taken to avoid the accidental operation of automatic fire detection or suppression systems, yet still maintain the full safety and protection of the building.

 

Prohibited Issuance.  Notwithstanding anything herein, a hot work permit may NOT be issued if a Hot Work Supervisor determines that there is an existence or possibility of the development of nearby combustible or flammable solids, liquids, dusts, vapors or gases or improperly prepared tanks or equipment which contain or have previously contained such materials and which cannot be removed or properly protected.

 

Prohibited Work Areas 

Hot Work shall not be conducted:

a.            in areas equipped with sprinkler systems that are out of order;

b.            in areas, including those with confined spaces, where atmospheres of explosive gases, vapors, or dusts exist or could accumulate;

c.            on containers where flammable liquids, solids, or vapors may be present;

d.            in areas with suspected lead-based paint or suspected lead-based painted components; or

 

Storage of Cylinders

Cylinders shall be stored at least twenty (20) feet from highly combustible materials and where the cylinders will not be exposed to excessive rise in temperature, physical damage, or tampering by unauthorized persons.  Cylinders must be chained at all times or otherwise secured to prevent them from falling over.  Oxygen cylinders must be separated from fuel gas cylinders or combustible materials at a minimum distance of twenty (20) feet or by a non-combustible barrier at least five (5) feet high, having a fire resistance rating of at least thirty (30) minutes. 

 

Posting

Hot Work Permit.  The permit shall be posted in a highly visible area at the hot work site

 

Warning Signs.  Signs, where appropriate, shall be posted to warn others of reasonably foreseeable danger.

 

After Hot Work

Remain on Site.  At least one worker must remain at the hot work site with access to the fire prevention and extinguishing equipment as required above for at least 30 minutes after hot work has been completed to detect and extinguish any possible smoldering fires.

Inspection.  The Hot Work Supervisor or designee must perform an inspection of the hot work and repossess the hot work permit and return it to the district’s central office. 

Disclaimer

This policy shall not relieve any person from following all laws and regulations dealing with hot work.
