The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, , the range statement and the assessment guidelines for the Training Package.

Overview of assessment

Successful assessment of this unit meets the competency requirement of the National Standard for Licensing Persons Performing High Risk Work.

State/territory OH&S regulators have mandated the use of Assessment Instruments and Instructions for Assessment for this unit which have been endorsed by the national body responsible for OH&S matters.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Compliance with OH&S licensing legislation.

Effectively communicate and work safely with others in the work area.

Risk assessment and management procedures (particular awareness of the risks associated with overhead powerlines/electrical cables, ground conditions, crane tipping and demolition sites).

Operation of a derrick crane for the lifting and moving of loads to the safe working rated capacity in conjunction with other associated personnel.

Appropriate mathematical procedures for the estimation of loads.

Context of and specific resources for assessment

Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instrument.

Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace setting.

Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is made available to suit the assessment and the workplace.

Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints.

Assessment is to comply with relevant appropriate standard requirements.

Applicants must have access to:

Personal Protective Equipment (PPE) for the purpose of the Performance Assessment.

appropriate derrick crane and associated equipment in safe condition specified by the endorsed Assessment Instrument

suitable loads as specified by the endorsed Assessment Instrument

communication equipment (e.g. two-way radios, whistles, etc.)

other associated personnel to sling and direct the loads.

Method of assessment

Assessment must be conducted using the endorsed Assessment Instruments. These Instruments provide advice on their application.

The use of 'simulators' in the assessment of this unit of competency is not acceptable.

Assessment may be in conjunction with the assessment of other units of competency.

Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.

Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Guidance information for assessment

Further information about endorsed Assessment Instruments may be obtained from state/territory OH&S regulators.

This describes the essential skills and knowledge and their level required for this unit.

Required skills:

Accurately record and maintain information relating to crane operations

Use communication techniques in the workplace including whistles, hand signals and use of two-way radios

Use interpersonal communication skills at a level sufficient to communicate with other site personnel

Operate a derrick crane for the lifting and moving of loads to the safe working rated capacity in conjunction with other associated personnel

Apply risk assessment and hazard control strategies, including hierarchy of control as applied to the safe operation of the crane (particular awareness of the risks associated with overhead powerlines/electrical cables and other personnel or vehicles)

Use and interpret crane manufacturer's specifications and data, or engineers specifications, assessments or designs, including load charts, or load limits at various radii, to enable the crane to be configured for the load

Verify problems and equipment faults and demonstrate appropriate response procedures

Required knowledge:

Appropriate mathematical procedures for estimation of loads

Commonwealth, state or territory OH&S legislation, standards and codes of practice relevant to the full range of processes for the crane class

Derrick crane characteristics and capabilities to allow for the operation of the crane to suit the range of loads

Level of literacy to be able to read and comprehend manufacturer's instructions, procedures and safety signs

Organisational and workplace standards, requirements, policies and procedures for conducting operations for the crane class

Derrick crane operating techniques

Understanding of the hierarchy of hazard identification and control

Procedures for the recording, reporting and maintenance of workplace records and information

Rated capacity and working load limits (including use of crane load charts)

Typical routine problems encountered in the operation of the crane and equipment and adjustments required for correction

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.

Hazards

May include but not limited to:

overhead hazards (e.g. powerlines, service pipes)

insufficient lighting

traffic (e.g. pedestrians, vehicles, plant)

environmental conditions (e.g. wind, lightning, storms)

other specific hazards (e.g. dangerous materials)

Hazard control measures

Refers to the systematic process of eliminating or reducing the risk to personnel and property through the application of controls

It includes the application of the hierarchy of control, the six-step preference of control measures to manage and control risk:

1 elimination

2 substitution
