2. HOT WORK PROCEDURES & PERMITIntrepid PolicyHot WorkHot work is any temporary or permanent operation that involves open flames or produces heat and/or sparks. This includes, but is not limited to, brazing, cutting, grinding, soldering, torch-applied roofing, and welding. The definition of hot work can be applied to activities within a facility, such as normal production processes, periodic/planned maintenance activities, new construction work, and emergency repairs. Hot Work PermitSpecial permit issued by an authorized authorityRevised 04/2014
3. HOT WORK PROCEDURES & PERMITIntrepid PolicyAlternative MethodsAlternative “cold work” methods include: Mechanically removing and relocating frozen piping to a heated area rather than thawing piping in place with any form of hot work Using manual hydraulic shears rather than a cut-off saw or torch Using mechanical bolting rather than welding Using screwed or flanged pipe rather than sweat soldering Using a reciprocating saw rather than a cut-off or radial saw Using a mechanical pipe cutter rather than a torch or radial sawRevised 04/2014
4. HOT WORK PROCEDURES & PERMITIntrepid PolicyProhibitionsHot work is prohibited where it cannot be conducted safely. However, hot work may proceed under the provisions of a specific written plan (authorized at the Superintendent level) designed to eliminate or mitigate the prohibitive conditions. ExamplesEquipment lined with rubber or other combustible materialsOxygen-enriched atmospheresAtmosphere containing flammable gasses or mists.Hot work on tanks or vessels containing flammable or combustible liquids Revised 04/2014Equipment lined with rubber or other combustible materials shall be effectively identified by appropriate signage, markings, notices or tags.
5. HOT WORK PROCEDURES & PERMITIntrepid PolicyPermitsPermits are issued for a specific job being done, and for a specific time period. The time period may extend for the full working shift and under rare circumstances, multiple shifts. Normally if job is not completed by shift-change a new permit will be issued and the old permit will be replaced and retained. A master log of current hot work activity and post-hot work fire watch and monitoring will be maintained at each facility. Each hot work permit tag displays a unique identification number that can be referenced on the master log. Revised 04/2014

7. HOT WORK PROCEDURES & PERMITIntrepid PolicyAuthorizationBased on the discretion of the authorizer, voice authorization of a hot work permit may be issued for hot work to be performed at remote locations. The permit must show the name of the authorizer and all required hot work safeguards must be implemented and documented on the permit. The authorizer must sign the permit before filing.Revised 04/2014
8. HOT WORK PROCEDURES & PERMITIntrepid PolicyDesignated Safe Hot Work AreasA Designated Safe Hot Work area is an area that has been designed and constructed to perform open flame or spark producing work with adequate ventilation. The Safety Manager and Operations Manager will determine if a given area qualifies as a designated safe hot work area. Permanent designated safe hot work areas will be identified by signage or other demarcation. Temporary designated safe hot work areas will be posted. These areas must continuously be free of combustible and flammable materials within 35’ of the work. All underground hot work not performed in designated shops must be permitted.Revised 04/2014
9. HOT WORK PROCEDURES & PERMITIntrepid PolicyEnclosed Tanks and VesselsAny time hot work is performed on any enclosed tank, or vessel that contains or previously contained flammable or combustible liquids precautions shall be taken to prevent the ignition of the liquids and/or vapors that may be generated within the containment during the hot work procedure. Such precautions may include, but are not limited to purging the containment with water or inert gas and must be documented on a Hot Work Permit. Revised 04/2014
10. HOT WORK PROCEDURES & PERMITIntrepid PolicyHot Work Distance RestrictionsFlammable liquids and combustible material removed from area (35’).Work area clean from combustible or flammable dust, lint and debris (35’).FM approved welding blankets and metal shields provided as needed (35’). All floor and wall openings (regardless of size) covered and/or protected, walls/ceilings: remove combustibles away from opposite side adjacent structures (35’).Underground, flammable gas tests shall be conducted in the affected area before initiating hot work, and at periodic intervals during the work. Surface or underground, such flammable gas tests shall be conducted whenever hot work is to be performed within 50’ of active gas lines.Hot work shall not be performed within 50’ of any explosives, blasting agent, active magazine or where explosives or blasting agents are being transported.Outdoor hot work shall not be performed in any area affected by wind currents in excess of 25 mph unless flammable and combustible materials are removed or protected in all directions for at least 50’ and/or other affirmative protective actions are taken.Revised 04/2014
