Plant and equipment may include: flue gas emission control systems associated with coal, gas, oil and biomass fired thermal power stations and oil and gas fired gas turbine and combined cycle power stations; AC and DC electrical distribution systems; electrical switchgear; electric motors; electric motor driven pumps and fans; valves, dampers and actuators (manual, electric, hydraulic and pneumatic); flue and/or exhaust gas temperature control equipment; storage hoppers and material conveying equipment; lubrication systems; station water distribution systems; hydraulic power oil systems; compressed air systems; distributed control systems; supervisory, protection, alarm and control equipment. Safety standards may include relevant sections of Occupational Health and Safety legislation, enterprise safety rules, relevant State and federal legislation, national standards for plant and Australian standards. Information and documentation sources may include verbal or written communications; enterprise safety rules documentation; enterprise operating instructions; computer-based and computer accessed documentation; 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 (auditory, olfactory, tactile, visual), local indicators and recorders, computers and alarms (visible and/or audible). Communications may be by direct personal interaction or by means of telephone, verbal or text-based telephone messaging, two way radio, pager, computer (electronic mail) and/or operating logs (written or verbal). Appropriate personnel for consultation, giving or receiving direction may include: supervisor/team leader or equivalent, power plant operations personnel or equivalent, technical and engineering officers or equivalent, maintenance staff, other operating staff or equivalent, system controller/network controller, field operator, restricted H.V. operators, independent generators and customers and contractor staff. Operating environment may be remote from the plant and equipment being operated, (in cases where operation is assisted by remote indication of operating parameters and plant status), during inclement or otherwise harsh weather conditions, in hot, wet, noisy, dusty, elevated, confined or enclosed areas or during night periods. Plant operations (systems requirements) may include: Returns to service with the heat recovery steam generator in a cold, warm or hot condition; heat recovery steam generator internal chemical clean; raising pressure to allow steam main blow-out; raising pressure to allow safety valve setting, operational testing. Operational tests may include: System calibration tests, stand-by plant "cut-in" tests; dampers/valves operating checks and pre and post start tests; performance tests and alarm initiation tests Faults and abnormal operating conditions may include: Loss of electrical supply to switchboards, drive motors or valve actuators; controlled emissions limits exceeded; automatic control loop(s) malfunctions; high flue gas or exhaust gas temperatures; high temperatures on/in: motor and/or pump bearings, lubricating oil or motor windings; high differential pressures on oil/air filters and strainers; failed field devices; failed/malfunctioning actuators/dampers/valves; emission control system protection operation.
