10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance. Plant and equipment may include electricity distribution system a.c. and d.c.; HV transformers; tap changers; HV switchgear; burner tilts; burner operations; precipitator plant; ash or dust plant; hydrogen/seal oil differential pressure controllers; stator temperature controller; hydrogen temperature controller; ammonia dosing controller; feed heater level controls; secondary air and flue gas dampers; turning gear barring equipment; rotary air heater barring equipment; sootblowing retracting equipment; reflux valve controls; condenser level controls; condenser backflushing equipment; oil temperature controllers; turbine gland sealing controllers; valves, actuators and dampers (electric, hydraulic, pneumatic and manual); supervisory, alarm and control equipment. Safety standards may include relevant sections of Occupational Health and Safety legislation, enterprise safety rules, relevant state and federal legislation and national standards for plant. Information and documentation sources may include verbal or written communications; enterprise safety rules documentation; enterprise operating instructions; dedicated computer equipment; enterprise/site standing and operating instructions; enterprise log books; manufacturer’s operation and maintenance manuals; and equipment and alarm manuals. Technical and operational indicators may include stimuli (audio, smell, touch, visual), remote or local indicators and recorders, computers and alarms (visible and or audible). Communications may be by means of telephone, two way radio, pager, computers (electronic mail) and operating log (written or verbal). Tests may include stand-by plant tests and post maintenance operating tests. Appropriate personnel to consult, give or receive direction may include supervisor/team leader or equivalent, system controller/power plant operator/unit controller or equivalent; technical and engineering officers or equivalent; maintenance staff; other operating staff or equivalent. Test, fault finding and operating tools may include high voltage testers, proving dead equipment, power or hand tools, control system equipment and specialised testing equipment. Operating environment may be remote from plant and equipment being operated (operation is assisted by remote indicators of plant status and other parameter monitors), during inclement or otherwise harsh weather conditions, in wet/noisy/dusty/hot areas or during continuous operation. Unit operations may include routine plant movement, spurious faults in automatic systems; automatic systems operating out of range and failure of automatic system component(s)... Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries. |
