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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Hazards may include but not limited to: | ground stability (eg. ground condition, recently filled trenches, slopes) overhead hazards (eg. power lines, service pipes) insufficient lighting traffic (eg. pedestrians, vehicles, other plant) environmental conditions (eg. wind, lightning, storms) other specific hazards (eg. 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: elimination substitution isolation engineering control measures using safe work practices personal protective equipment. |
Appropriate standards may include: | codes of practice legislation Australian Standards, manufacturer's specifications industry standards (where applicable). |
Concrete placing boom may include: | a mobile truck mounted plant incorporating a knuckle boom, capable of power operated slewing and luffing to place concrete by way of pumping through a pipeline attached to, or forming part of, the boom of the plant. |
Communication methods may include but not limited to: | verbal and non-verbal language written instructions signage hand signals listening questioning to confirm understanding appropriate worksite protocol. |
Appropriate personnel may include but are not limited to: | those associated with the operations of the concrete placing boom supervisors suppliers clients colleagues managers. |
Procedures may include but are not limited to: | manufacturer's guidelines (range chart, instructions, specifications or checklists) industry operating procedures workplace procedures (work instructions, operating procedures, checklists). |
Service logbook may include but is not limited to: | any logbook service book history record system where the service and maintenance history is kept. |
Hoppers may include but not limited to: | large receptacles mounted on the concrete placing boom which receive the concrete from supply vehicles and dispense the concrete to the pumping system. |
Communication equipment may include but not limited to: | fixed channel two way radios mobile phones. NB: where radio communication equipment is used the transmitting frequencies of the equipment must be selected to prevent interference to or from other radio equipment being used in the vicinity of the crane. |
Ground suitability may include but not limited to: | rough uneven ground backfilled ground soft soils hard compacted soil rock bitumen concrete. |
Stability may include but not limited to: | deploying outriggers establish correct size plates or packing correctly position plates or packing. |
Safety devices may include but not limited to: | horns/sirens audible and visual reversing devices 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). |
