10) The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Appropriate standards may include, but not be limited to: codes of Practice; legislation; Australian standards and manufacturers’ specifications.Communicated/Communication may include, but not be limited to: verbal; written; telephone; two-way radio; log records and computer record systems.Emergencies may include, but not be limited to: fire; bomb threat; terrorism; personal accidents; chemical spills; major steam leaks; major water leaks and flooding and natural disasters.Equipment may include, but not be limited to: engine and auxiliary plant; engine lubrication and power or control oil systems; hydraulic oil system; pump; compressed air system; steam supply system; cylinder exhaust system; computers with equipment control functions; supervisory, alarm, protection and control equipment and Relevant maintenance equipment.Also to include equipment for: lock out for protecting operators and co-workers from accidental injury; emergency shutdown stopping; extinguishing fires; organisational first aid requirements and evacuation.Equipment faults may include, but not be limited to: abnormal operating conditions; loss of a major auxiliary; excessively high engine and engine valves heating rates or differentials; high engine bearing temperatures or vibration; high pressure heaters malfunctions; mechanical or electrical faults or failure and failed field devices and engine protection.Hazards may include, but not be limited to: chemical hazards; thermal hazards; manual handling hazards; guarding of machinery requirements; illumination of work area; rubbish and combustibles in area; leakage of steam; leakage of fuel; obstructions in the work area; fire; noise; vibration; water and working at heights.Operational checks may include, but not be limited to: supply and quality of steam and line pressure; exhaust system; safety devices; speed governor; vibration level; lubrication system; operation and function of valves and fittings; cylinder drainage system and operation of control/safety devices.Personal Protective Equipment (PPE) may include, but not be limited to: prescribed under legislation, regulation, codes of practice, and workplace policies and practices; hard hat; safety boots; gloves; high visibility clothing; breathing, hearing, sight, skin and sun protection; fall-arrest equipment such as harnesses and lanyards, horizontal life lines and inertia reel.Pre-operational safety checks may include, but not be limited to: supply steam system; position and operation of engine valves; lubrication system; cylinder drainage system; exhaust system; auxiliary equipment; safety devices; over speed shut down; pressure relief devices and speed governor.Procedures may include, but not be limited to: manufacturer’s guidelines (instructions, specifications or checklists); industry operating procedures and workplace procedures (work instructions, operating procedures, checklists).The operation of steam equipment where the steam acts upon a piston under pressure where this action of the steam forces the piston to move. The definition includes all expanding (steam) reciprocating engines, with any piston diameter of greater than 250 millimetres.Recorded may include, but not be limited to: operations and maintenance of reciprocating steam engine equipment; difficulties or issues; environmental issues; recommendations for future work; results; costs; hazards; incidents or injuries; dangerous occurrences or equipment; malfunctions using log books; proformas; production reports and maintenance recordsShut down checks may include, but not be limited to: steam supply; cooling process; load on engine; cylinder drains and auxiliary equipment.Shut down checks for maintenance may include, but not be limited to: checks of cooling down process; isolation of steam; isolation from any common connection and opening of all access points required for inspection.A simulator is a device used especially in training to reproduce the conditions of the working situation, enabling tasks to be learned and practised safely and economically.Start-up checks May include, but not be limited to: heat input; steam supply system; steam traps and steam line purge systems operation; engine warmed up; lubrication system; drainage system; operation and position of engine valves and fittings; operation of auxiliary equipment; freedom of rotation of engine; warm up of reticulation system and reticulation line pressure.Testing May include, but not be limited to: loss of a major auxiliary controls response checks; stand-by plant “cut-in” tests; valves operating checks; on-load engine valve and emergency governor operation test; performance tests; valve operation tests and alarm and protection tests. |
