Elements and Performance Criteria

1. Plan and prepare for operations
   • Receive and give shift handover
   • Identify work requirements
   • Identify and control hazards
   • Coordinate with appropriate personnel
   • Check for recent work undertaken on screens
   • Note any outstanding/incomplete work
   • Check operational status of screens
   • Check screen feed and discharge areas for obstructions and hazards
   • Complete any required pre-start checks
2. Operate screening plant in accordance with procedures
   • Identify the type of screen and its duty
   • Complete routine checks, logs and paperwork
   • Monitor feed and discharge rates to ensure efficient and safe screen operation
   • Take action required by procedures
3. Recognise and take action on abnormal situations in accordance with procedures
   • Monitor screens frequently and critically throughout shift using measured/indicated data and senses as appropriate
   • Identify impacts of any changes upstream and downstream
   • Recognise situations which may require action
   • Resolve routine problems
   • Take actions on other abnormal situations to make safe and have the situation resolved
4. Isolate and de-isolate screening equipment
   • Complete any required pre-start checks
   • Start up/shut down screens according to the screen type and duty in liaison with other personnel
   • Isolate screening equipmen
   • Make safe for required work.
   • Check screening equipment is ready to be returned to service
   • De-isolate and prepare screening equipment for return to service

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Regulatory framework	The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following: legislative requirements, including work health and safety (WHS) industry codes of practice and guidelines environmental regulations and guidelines Australian and other standards licence and certification requirements All operations to which this unit applies are subject to stringent health, safety and environment (HSE) requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the HSE requirements take precedence.
Procedures	All operations must be performed in accordance with relevant procedures. Procedures are written, verbal, visual, computer-based or in some other form, and include one or more of the following: emergency procedures work instructions standard operating procedures (SOPs) safe work method statements (SWMS) formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant
Hazards	Hazards include one or more of the following: electricity structural hazards structural collapse equipment failures industrial (machinery, equipment and product) equipment or product mass noise, rotational equipment or vibration limited head spaces or overhangs working at heights, in restricted or confined spaces, or in environments subjected to heat, noise, dust or vapours flammability and explosivity hazardous products and materials unauthorised personnel sharp edges, protrusions or obstructions slippery surfaces, spills or leaks extreme weather other hazards that might arise
Routine problems	Routine problems must be resolved by applying known solutions. Routine problems are predictable and include one or more of the following: feed or discharge blockages blinding screen/cloth blockages electro-static build-up over/under size contamination Known solutions are drawn from one or more of the following: procedures training remembered experience Non-routine problems must be reported according to according to relevant procedures.
Action on abnormal situations	Action on abnormal situations includes the following determining problems needing action determining possible fault causes rectifying predictable problems using appropriate solution from procedures following through items initiated until final resolution has occurred reporting problems outside area of responsibility/scope of procedures to designated person
Logs and reports	Logs and reports include one or more of the following: paper or electronic-based logs and reports verbal/radio reports reporting items found which require action
Screening equipment types	Screening equipment includes one or more of the following: moving screen static screen rotary screens circle-throw/vibrating equipment high frequency vibrating equipment gyratory equipment
Work requirements	Work requirements come from briefings, handovers and work orders and include one or more of the following: compliance documentation product specifications nature and scope of tasks achievement targets operational conditions geological data site survey data site layout and out of bounds areas worksite inspection requirements lighting conditions plant or equipment defects hazards and potential hazards coordination requirements or issues
