Elements and Performance Criteria

1. Prepare for work
   • Receive and give shift handover
   • Identify work requirements
   • Identify and control hazards
   • Coordinate with appropriate personnel
   • Check for recent work undertaken on filter
   • Note any outstanding/incomplete work
   • Check operational status of filter
2. Operate filter
   • Identify the types of filter and its duty
   • Complete routine checks, logs and paperwork taking action in accordance with procedures on unexpected readings
3. Recognise and take action on abnormal situations in accordance with procedures
   • Monitor filter frequently and critically throughout shift using measured/indicated data and senses
   • 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 filter
   • Complete any required pre-start checks
   • Start up/shut down/changeover filter according to the filter type and duty in liaison with other personnel
   • Isolate filter
   • Make safe for required work
   • Check filter is ready to be returned to service
   • De-isolate and prepare filter 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 gas gases and liquids under pressure structural hazards structural collapse equipment failures industrial (machinery, equipment and product) equipment or product mass noise, rotational equipment or vibration plant services (steam, condensate and cooling water) working at heights, in restricted or confined spaces, or in environments subjected to heat, dusts 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: control pressure effects on upstream and downstream plant clogging seal/gasket leaks pressure loss/low flow cartridge/filter change blockages/build-up/fouling erosion/wear 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 problem using appropriate solution within area of responsibility following through items initiated until final resolution has occurred reporting problems outside area of responsibility to designated person
Filtration equipment	Filtration equipment includes the following: filters and membranes, such as plate and frame filters, leaf filters, cartridge filters, bed (sand/gravel) filters and disk/edge filters pressure/flow monitoring equipment minor equipment to supply filter and remove filtrate/cake which is integral to the operation of the filter
Operate	Operate is to monitor, adjust/change the plant item/unit/system to meet specifications, by one or more of the following: manually in the plant using local controller in the plant using the process control system in the control room
Start up/shut down as required	Start up/shut down as required includes the following: start up and shut down to/from normal operating conditions start up and shut down to/from isolated, cold or empty start up and shut down to/from other conditions/situations experienced on the plant
