1 PURPOSE To specify the minimum requirements for controlling risks associated with Hot Work activities. 1 SCOPE This procedure defines Hot Work as any activity that may introduce a source of ignition or heat to an area where flammable or combustible materials are present, stored or handled in quantities sufficient to produce a fire or explosion. Hot Work activities include, but are not limited to: Welding Use of equipment with naked flames Use of equipment with heated elements Use of equipment that may produce a spark during operation Work which may produce incendiary sparks Use of cartridge-operated tools and other explosive devices This procedure further defines General Hot Work as work where welding, oxy cutting, grinding or heating is conducted in the vicinity of combustible material. This procedure applies to Hot Work activities conducted within areas controlled by the University of Canberra. All persons shall comply with the requirements of this procedure. This procedure shall be read in conjunction with the Permit to Work System Guideline POL-1000, Isolation Lockout and Tagging PRO-1060, Barriers and Barricading PRO-1080 and Confined Space Work PRO-1020 and any other relevant Permit to Work procedures. 2 PROCEDURE 2.1 Requirement for FRM-1041 Permit to Work Hot Work and FRM-1001 Job Safety Analysis (JSA) As per POL-1000 Permit to Work System Guideline, FRM-1041 Permit to Work - Hot Work shall be authorized before hot work may commence In addition, Appendix 1 of FRM-1041 Special Considerations shall be completed and authorized for areas requiring special consideration. PRO-1040 V1.0 Hot Work.doc Page 1 of 22

2 2.1.3 In addition, Appendix 2 of FRM-1041 Hazardous Zone or Area shall be completed and authorized before performing work in areas which have potentially explosive atmospheres Where a safe work procedure has been established for Hot Work in an area designed for this work, the area manager may waive, in writing the need for a FRM-1041 Permit to Work Hot Work. Refer to section 2.14 Designated Hot Work Areas. 2.2 Areas Requiring Special Consideration Areas in which fire could spread rapidly, fumes or fire protection gas could displace or change oxygen levels, or where fire could be enclosed, require special consideration. Such areas include, but are not limited to: Locations such as shafts and airways where fumes could displace or change oxygen levels Timber-lined structures (e.g. a building.) Confined spaces Locations with oxygen-depleting fire systems (e.g. substations, control rooms, information technology server/ switching rooms). Hazardous areas 2.3 Hazardous, Potentially Flammable Atmosphere A potentially flammable atmosphere is one having potentially explosive gas, vapour and/or combustible dust present. Potentially flammable areas include, but are not limited to: Flammable liquid fuel storage and handling facilities (e.g. fuel pipes, cabinets, tanks and pumps) Portable flammable liquid tank storage containers (e.g. petrol, kerosene) Flammable gas storage or piping systems (e.g. natural gas, LPG, acetylene) Diesel fuel storage is not classified here as hazardous. 2.4 Risk Assessment As per POL-3203 UC Risk Management Plan and tools, a written risk assessment shall be completed by knowledgeable, experienced persons before HOT Work may be authorized. This written assessment can be (or shall include) a completed FRM-1001 Job Safety Analysis (JSA). This risk assessment may include, but is not limited to: The nature and inherent hazards of the intended activity All sources of potential heat and/or ignition Removal, isolation or wetting down of combustible sources PRO-1040 V1.0 Hot Work.doc Page 2 of 22

3 Ventilation Range of methods by which the work can be performed Hazards and associated risks of the chosen work method, equipment and tools Emergency and rescue/recovery procedures Access to fire protection and firefighting equipment Need for and duration of Fire Watch Availability of relevant personal protective equipment Competence of persons undertaking the work Competence of persons supervising the work The risk assessment shall be revised whenever evidence indicates that it is no longer valid or when the scope of the work changes The nature of the activity and the work environment shall determine both the need for and level of skill and experience required by the Safety Observer performing Fire Watch. a. ACT Fire & Rescue - ACT Emergency Services personnel shall be used as Specialist Fire Watch whenever hot work is conducted in hazardous areas with Hazardous Zones or Areas and/ or which contain Special Consideration b. A Trained and authorized Safety Observer may perform as Fire Watch for General Hot Work Activities c. Where FRM-1041 Permit to Work Hot Work is required, the risk assessment may recommend specialist personnel to conduct the Fire Watch Before hot work is authorized on any surface covered with a preservative or other coating or lining, an investigation into the combustibility and thermal decomposition of the coating shall occur. If the coating is deemed combustible as a result of hot work activity, it shall be stripped from the area to prevent ignition. When choosing the stripping method, the risk assessment shall also consider the combustible nature of the coating and determine whether a charged fire hose or other suitable extinguishing equipment is required. 2.5 Areas that have Oxygen-Depleting Fire Systems Fixed fire-extinguishing equipment that employs an extinguishing agent which may be harmful to workers shall be isolated as per PRO-1060 Isolation and Tagging before personnel perform hot work. 2.6 Hidden or Developing Explosive Atmospheres Ignition Sources Vents, flanges, valves, drains or connections in containment systems may result in small leaks or weeps which could create an explosive atmosphere in an unexpected area. PRO-1040 V1.0 Hot Work.doc Page 3 of 22

4 2.6.2 If containment systems fail or become open or breached, the explosive atmosphere could extend well beyond the documented Hazardous Area classification Risk Assessments shall consider the likelihood of hidden or developing explosive atmospheres. 2.7 Location where Fumes from Hot Work could Displace or Change Oxygen Levels (e.g. shafts, airways and intakes) Fumes can be generated from arc, oxy and acetylene and rubber welding and /or cutting/grinding activities that cause smoldering of combustibles Personnel planning to perform Hot Work in locations where fumes could displace or change oxygen levels in (shafts, airways and intakes) shall consider the following hazards: Rapid spread of fire Generation of fumes Change in Oxygen levels Duration of fire watch 2.8 Timber Lined Structures (Buildings etc.) Personnel planning to perform Hot Work in or near timber-lined structures shall consider the following hazards: Access to prevent fire spreading (firefighting) Safe distance from timber structure while performing hot work Delayed fire ignition Rapid fire spread Duration of fire watch 2.9 Confined Space Considerations Weather, temperature, wind speed and direction The following hazards shall be considered by personnel planning to perform Hot Work within or near a confined space. Flammable atmospheres around confined space Ventilation: low ventilation may result in rapid generation of flammable atmospheres Generation of fumes Duration of fire watch When welding or cutting a tank or a heat conductive boundary of a confined space, the same precautions shall be exercised inside and outside the space where the hot work is being conducted. Sparks from direct penetration or heat transfer may create an explosion or fire hazard in the adjacent spaces outside the confined space. PRO-1040 V1.0 Hot Work.doc Page 4 of 22

5 2.9.3 Means shall be provided to exhaust airborne contaminants from the confined space. The exhaust suction point shall be located as close as possible to the source of contamination within the confined space (e.g. close to metal being welded). Exhaust shall be directed to a location where it presents no hazard to others and will not accidently re-circulate into the confined space or other adjacent airway or intake Minimising potential ignition of a flammable atmosphere inside a Confined Space When arc welding is suspended for a substantial period such as during lunch breaks or overnight the power source to the equipment shall be deenergized, all electrodes removed from holders and the holders placed in a manner that prevents accidental contact or arcing. When gas welding or cutting is suspended for a substantial period such as lunch breaks or overnight then torch and cylinder valves shall be closed. The torch and hose shall be removed and depressurized outside the confined space. No flammable compressed gas cylinders or associated manifolds shall be located inside the confined space Risk Management and Control All combustibles shall be removed from the proposed work area. Where this is not possible e.g. rubber lined vessels, suitable protection measures shall be implemented Housekeeping shall be maintained for the duration of the task Personnel shall be vigilant throughout the task as changing conditions may introduce new hazards. Such conditions may include weather, wind, personnel, equipment, consumables, other work or work groups Where there is a potential for an explosive atmosphere, arrangements shall be made to control by removing, isolating or lowering the explosive limit before work commences When working in potentially flammable atmospheres, the following shall be implemented: Removal and/or isolation of flammable sources Prohibition on the introduction of ignition sources into potentially flammable atmospheres. Gas detection or monitoring of the lower explosive limit of the atmosphere as per Appendix 5 Gas Detectors of PRO-1020 Confined Space Work.
