10) Range: This relates to the unit of competency 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. Chemical conditions monitored and operated may include pH, conductivity, acid conductivity, silica, dissolved O2, ammonia, totally dissolved solids, phosphate, oxidisation reduction potential, sodium ion and chlorine residual. Systems, plant and/or equipment may include raw water, feed water, condenser cooling water, auxiliary cooling water, demineralised water, water treatment plant, water quality room, ammonia and hydrazine systems, hypochlorite plant, effluent disposal system, reverse osmosis plant pumps, high/low pressure, characteristics, operating conditions valves, actuators (electric, pneumatic) electrical supply switchboards electrical motors (high and low voltage) supervisory, alarm and control equipment filters, strainers, dryers, moisture, pressure control devices, safety devices and high and low pressure systems. 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/form(s) equipment and alarm manuals dedicated computer equipment enterprise/site standing and operating instructions enterprise log books and manufacturer’s operation and maintenance manuals. Technical and operational indicators may include stimuli (audio, smell, touch, visual), local indicators and recorders and alarms (visible and/or audible). Communications may be by means of telephone, two way radio, pager, public address system, computer (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, technical and engineering officers or equivalent, maintenance staff, power plant operations personnel and contractor and specialist staff. Test, fault finding and operating tools may include chemical analysis equipment, power or hand tools, control system equipment and leak test equipment. Operating environment may be remote from plant, aided by indicators and monitors, during inclement or otherwise harsh weather conditions, in wet/noisy/dusty areas or during night periods. Faults and abnormal operating conditions may include motor/pump/ actuator/valve/damper failure/malfunctions, control equipment failure/ malfunctions, loss of electrical supply to plant and equipment, loss supply, low water pressure, burst pipes, plant/equipment, loss of major auxiliary (dosing plant) and loss of station air supply. 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. |
