Range Statement
The range statement indicates the context for demonstrating competence. This statement is a guide and unless otherwise indicated, items may or may not apply as required by the work context.
Work is carried out in accordance with company policies and procedures, licensing requirements, manufacturer's recommendations, legislative requirements, codes of practice and industrial awards and agreements. Codes of practice include the Sugar Milling Operations Industry Code of Practice
Workplace information can include Standard Operating Procedures (SOPs) and manufacturer's specifications
Boiler (advanced) covers boilers with the same features as Intermediate Boilers - that is they may have any or all of the following features: - modulating combustion air supply, modulating heat source, superheaters, and economisers. However Advanced boilers must also have multiple fuel types which may be fired simultaneously during normal operation. This does not include boilers that change fuel type during start sequence.
Operation and monitoring of equipment and processes typically requires the use of control panels and systems
Services can include fuel supply of bagasse, coal, gas, oil or other fuel types, steam, mill and instrumentation air, cooling water, general mill water supply and cooling water
Confirming equipment status involves conducting relevant pre-start checks, confirming that cleaning standards are met, all safety guards and manholes are in place and equipment is operational
Internal cleaning is carried out in accordance with statutory requirements regarding confined space entry and does not typically include chemical cleaning
Work may require the ability to work within a team environment
