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 boiler and auxiliary plant; fuel and fuel delivery system plant; fuel management system; flame detection equipment; steam temperature control plant; boiler heating surfaces dust removal system; combustion waste extraction system; electric motors (a.c. and d.c., high and low voltage); electricity distribution system (a.c. and d.c. transformers); diesel engine driven auxiliary plant; station water distribution systems; hydraulic power oil system; compressed air systems; computers with equipment control functions; and supervisory, alarm and control equipment.Safety standards may include relevant sections of Occupational Health and Safety legislation, enterprise safety rules, Australian standards, national standards for plant and relevant State and federal legislation.Information and documentation sources may include verbal or written communications; enterprise safety rules documentation; enterprise operating instructions; manufacturer’s operational and maintenance manuals; equipment and alarm manuals, enterprise log books, dedicated computer equipment, enterprise standing instructions and plant notes.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, computer (electronic mail) and operating log (written or verbal).Tests may include loss of a major auxiliary controls response checks, stand-by plant “cut-in” tests, dampers/valves operating checks and pre and post shut-down tests.Appropriate personnel to consult, give or receive direction may include supervisor/team leader or equivalent; other coordinators of energy production or equivalent; technical and engineering officers or equivalent; maintenance staff; other operating staff and contractor staff.Operating environment may be remote from plant and equipment being operated (operation is assisted by remote indicators of plant status and other parameters monitored); in wet/noisy/dusty/hot areas, during night periods and during inclement or otherwise harsh weather conditions.Plant operations (systems requirements) may include boiler emergency trip; boiler shutdown, with or without turbine bypass or by using forced cooling procedures.Faults and abnormal operating conditions may include boiler trip; loss of a major auxiliary; loss of electrical supply to switchboard(s), motors; boiler water chemical operating limits exceeded; automatic control loop(s) malfunctions; boiler heating surfaces dust removal system malfunctions; high temperatures on/in, boiler heating surfaces/tubes/headers, boiler exhaust (back end), steam to turbine, motor, fan, pump bearings and lubricating oil, motor windings; boiler tube leaks; air heater cold end temperatures low; air heater/combustion air ductwork fires; fuel preparation and delivery systems fires; fuel system malfunction; excessive drum water level split; excessively high heating/cooling rates; high/low furnace dp; high dp’s on oil/air filters and strainers; failed field devices (pressure/level switches/transmitters, thermocouples); failed/ malfunctioning actuators/dampers/valves; boiler feedwater pumps malfunctions and boiler protection.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. |
