operator restraint devices (where applicable)
lights
safety interlocks.
Hazard prevention/control measures may include but not limited to:
safety tags on electrical switches/isolators
powerlines are insulated
safety observer used inside exclusion zone
power disconnected
traffic barricades and control
pedestrian barricades
trench covers
movement of obstructions
personal protective equipment
adequate lighting
earth chain.
Supply vehicle may include but not limited to:
cement mixer trucks
agitator trucks
other concrete transport vehicles.
Relevant boom movements may include but not limited to:
raising boom
lowering boom
slewing
knuckling.
Safe operating techniques may include but not limited to:
achieving a safe optimum output from the concrete delivery system within the manufacturers design specifications
ensuring hopper levels are maintained at safe and recommended levels
safe operation of the boom to ensure safety of operator and other personnel
managing engine power to ensure efficiency of concrete pump truck platform movements and to minimise damage to the engine and gears
coordinating engine power with gear selection ensuring smooth transition and operation within torque range.
Communication signals may include but not limited to:
boom up - hand
boom down - hand
boom left - hand
boom right - hand
open or extend boom -hand
close or retract boom - hand
stop boom - hand
start pump speed up - hand
slow pump down - hand
little bit - hand
add water - hand
all done clean-up - hand.
Unplanned and/or unsafe situations may include but not limited to:
failure/lose of control e.g. blown hose or concrete line
failure of equipment e.g. hydraulic system
environmental conditions (e.g. wind, lightning, storms, etc).
Shut down may include but is not limited to:
retracting boom
positioning/securing boom
retracting outriggers/stabilisers
idle engine to stabilise temperature
disengage PTO (where applicable)
turning off engine (where applicable)
remove key from ignition (where applicable)
lock and secure cabin (where applicable).

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, 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 OHS 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 OHS matters.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
comply with OHS licensing legislation
assess ground conditions to confirm that the site is suitable (e.g. firm, level and safe) to erect the concrete placing boom.
assess risk and hazard control strategies, including hierarchy of control as applied to the positioning and safe operation of the concrete placing boom (particular awareness of the risks associated with overhead powerlines/electrical cables, ground conditions, wind, pedestrians and tipping)
complete the pre operational check, positioning, stabilising, set up, operation, post operational checks of a concrete placing boom including all functions to their maximum extension in the moving of the boom and placement of concrete to the safe working rated capacity of the concrete placing boom
operate the concrete placing boom in conjunction with other appropriate personnel (where applicable).
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 concrete placing boom and associated equipment in safe condition
communication equipment (e.g. two way radios, etc) where appropriate
other appropriate personnel to direct the placement of concrete (where applicable).
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 OHS regulators.
