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 lightingtraffic (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 practicelegislationAustralian Standards,manufacturer's specificationsindustry 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 languagewritten instructionssignagehand signalslisteningquestioning to confirm understandingappropriate worksite protocol. |
Appropriate personnel may include but are not limited to: | those associated with the operations of the concrete placing boomsupervisorssuppliersclientscolleaguesmanagers. |
Procedures may include but are not limited to: | manufacturer's guidelines (range chart, instructions, specifications or checklists)industry operating proceduresworkplace procedures (work instructions, operating procedures, checklists). |
Service logbook may include but is not limited to: | any logbookservice bookhistory 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 radiosmobile 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 groundbackfilled groundsoft soilshard compacted soilrockbitumenconcrete. |
Stability may include but not limited to: | deploying outriggersestablish correct size plates or packingcorrectly position plates or packing. |
