Legislation, Standards and Duty of Care for Concrete Placing Booms
The framework you must know
Concrete placing booms sit at the intersection of work health and safety (WHS) law, plant-specific licensing, and Australian Standards. Under the model WHS Act and Regulations (mirrored in each state and territory with local variations), a concrete placing boom is "plant" and often "high risk plant" requiring a high risk work licence for the boom operator. Know the primary duty of care: a person conducting a business or undertaking (PCBU) must ensure health and safety so far as reasonably practicable. Officers have due diligence duties; workers must take reasonable care for themselves and others, follow instructions, and report hazards.
Concepts candidates must understand
Registration and design notification of plant, licensing and competency requirements, the hierarchy of control, consultation and issue resolution, and record-keeping for inspections and maintenance. The plant-specific standards that matter are the AS 2550 crane series (particularly the general requirements and the mobile/boom-adjacent parts) and the concrete placing equipment standard AS 2550.15, plus AS 1418 series for the equipment design. Site-specific safe work method statements (SWMS) are mandatory for high risk construction work, and boom setup near overhead powerlines triggers specific exclusion-zone rules.
Traps in exam questions
Questions often test who holds which duty rather than the technical detail - for example, the operator is not solely responsible for ground conditions; the PCBU must provide a suitable, assessed setup location. Another trap is assuming a licence permits any boom; licences are class-specific and competency must be verified for the actual equipment. Also watch for questions implying that a SWMS replaces a risk assessment - it does not; it documents the controls.
Worked rule of thumb
If unsure who is responsible, apply the test: "Who has management or control of the activity?" That party owns the duty. If multiple parties do, duties are concurrent, not transferred.
