The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Context | This competency includes breaking and making flange joints using hand tools. It does not include the use of: pneumatic torqueing tools hydraulic torqueing tools powered torqueing tools |
Work requirements | Work requirements may include but are not limited to: flange and gasket specifications stud and nut specification process line and process materials parts and equipment required local detectors requiring isolation required skill level conflicting work Work requirements may come from briefings, handovers, and work orders and may include: compliance documentation product specifications nature and scope of tasks achievement targets operational conditions lighting conditions plant or equipment defects hazards and potential hazards coordination requirements or issues |
Job site | Inspecting job site may include but is not limited to identifying: location authorisations required access and egress needs hazards recent work undertaken on joint flange type (matches specification) |
Control hazards | Control hazards may include but is not limited to: selection and use of appropriate personal protective equipment obtaining appropriate authorisations checking required isolations controlling other work in area |
Implement hazard controls | Implementing hazard controls may include but is not limited to: controlling access to area using gas tester verifying and confirming isolation safe flange breaking procedure (line of fire) |
Manage open pipe | Manage open pipe includes: all those actions required once the flange is broken to ensure the pipe and its contents are not contaminated or damaged |
Inspect components | Inspecting flange components may include but is not limited to: checking for asbestos in gaskets looking for signs of damage, defects or deterioration in all components cleanliness and correct surface roughness of mating surfaces alignment Refer to appendices of ASME PCC-1-2010 Guidelines for Pressure Boundary Bolted Flange Joint Assembly for technical details |
Components | Components may include but are not limited to: studs nuts washers gaskets |
Check studs and nuts | Checking studs and nuts may include but is not limited to checking: integrity of studs and nuts fit of nut to stud need for new studs and nuts conformance to specification |
Initial assembly of joint | Initial assembly of joint may include but is not limited to: aligning joint inserting studs assembling nuts to studs inserting and aligning gasket |
Blinds | Blinds may include but are not limited to: blinds blanks spectacle/goggle blinds |
Refer | Refer means to refer the issue to the person with the required skills, knowledge and/or authority to deal with the matter |
Procedures | Procedures may be written, verbal, computer-based or in some other form. They may include but are not limited to: flange management procedures all work instructions standard operating procedures temporary instructions any similar instructions provided for the smooth running of the plant good operating practice as may be defined by industry codes of practice Procedures would be expected to comply with any relevant government regulations. |
Checklists and records | Checklists and records may include: paper or electronic based and verbal/radio reports reporting items found which require action |
Appropriate action | Appropriate action includes but is not limited to: determining problems needing action accessing and applying relevant technical and plant data applying appropriate problem solving techniques to determine possible fault causes rectifying problem using appropriate solution within area of responsibility following through items initiated until final resolution has occurred reporting problems outside area of responsibility/ability to resolve to designated person |
Typical problems | Typical problems may include but are not limited to: seal/gasket leaks pressure loss/low flow blockages/build-up/fouling erosion/wear ancillary equipment problems studs incorrectly tensioned worn threads misalignments cold pull isolation failure leak test failure |
Remedial actions | Remedial actions may include but are not limited to: replacing existing components with new components carrying out minor maintenance within operator's skill level identifying and reporting problems outside operator's competence identifying and controlling hazards related to flange joints |
Health, safety and environment (HSE) | All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence. |
