Modification History
Release 3 - Title corrected to 'Licence'.
Release 2 – Content reinstated following Safe Work Australia approval. Editorial changes to clarify WHS Regulations.
Release 1 - New unit of competency, endorsed by NSSC. Content not available pending endorsement by Safe Work Australia, the national agency for Work Health and Safety (WHS) high risk work licensing purposes.
Unit Descriptor
This unit of competency covers the operation of a standard boiler that uses a single fuel source and does not have a pre-heater, superheater or economiser attached.
Operation includes boiler start up, handover, monitoring, shut down and storage. Also covered are preparation for inspection procedures as specified in manufacturer recommendations, identification of maintenance requirements and relevant risk control measures.
Application of the Unit
The standard boilers covered by this unit would typically include boilers with fixed and modulating combustion controls, fixed and modulated air supply, and a single heat source. Operation may include a battery of boilers and boilers that have a single thermal or solar heat source. Boilers meeting the definition of ‘advanced boiler’ are excluded.
This unit in its current form meets state and territory high risk work licensing requirements. Any alteration to the content or outcomes would not be acceptable to regulators for the purpose of licensing.
Licensing/Regulatory Information
This unit is based on the licensing requirements of Part 4.5 of the Model Work Health and Safety (WHS) Regulations, High Risk Work.
