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.

Equipment and tools

Equipment and tools include one or more of the following:

crucibles

siphoning equipment

mobile transporting equipment

harnesses and slings

materials handling equipment

hand tools

Procedures

All operations must be performed in accordance with relevant procedures.

Procedures are written, verbal, visual, computer-based or in some other form, 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:

heat (e.g. burns, dehydration and heat stress)

energy sources (e.g. hydraulic, pneumatic and electric)

electromagnetic effects

high pressure piping and valves

pinch and crush points

moisture

banned items

mobile equipment and pedestrian interaction

suspended loads and roller conveyors

hazardous materials (e.g. chlorine)

molten materials

equipment failures

industrial (machinery, equipment and product)

equipment or product mass

noise, rotational equipment or vibration

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:

delivery of molten metal from reduction cells to clean crucible

pipe failures (e.g. cracks and blockages)

venturi and siphon system failure

siphoning suction equipment failure

out-of-parameter operation or product

fluctuation in temperature, power consumption or product movement

instruments and equipment requiring cleaning

equipment mechanical and electrical problems

flow path blockages

out-of-parameter emissions

unavailability of equipment, personnel or material

Known solutions are drawn from one or more of the following:

procedures

training

remembered experience

historical data and records of common faults

troubleshooting lists and directives

site procedures

Non-routine problems must be reported according to according to relevant procedures.

Instrument/electrical systems

Instrument/electrical systems include one or more of the following:

emergency shutdown systems (ESD)

fire systems

pressure and temperature control systems

communications systems

utility systems

Operate

Operate is to monitor, adjust/make change to the production unit and/or its component items to meet specifications, by one or both of the following:

manually in the plant

using local controller in the plant

Pre-start checks

Pre-start checks will conform to site procedures or equipment pre-start checklist. They must be completed before the equipment is operated unless stated in the procedures.

Reports and records

Reports and records include one or more of the following:

routine inspections (daily readings and monthly checks)

scheduled maintenance activities

computer readouts locally or in the control room

shift log sheet

mandatory or statutory inspections

hazard, accident and incident reports

quality inspection reports of the product

Shutdown procedures

Shutdown procedures must follow equipment and site-authorised checklist and will typically include the following:

communication to supply and delivery areas

communication to impacting areas

obtaining appropriate authorisations

rescheduling operations

liaison with maintenance teams

Start-up procedures

Start-up procedures must conform to site procedures and will typically include the following:

safety and pre-start checks

accessing shift logs and equipment records

pre-shift briefing information

records and reports from the previous shift

Work requirements

Work requirements will be identified from one or more of the following:

shift briefings

shift logs

supervisor or crew leader meetings

toolbox talks

handover details
