10) This relates to the unit of competency as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance. This Competency Standard Unit shall be demonstrated in relation to cutting and/or pruning vegetation at ground level and removal of vegetation obstructions up to the live work zone as defined for both Authorised and Instructed Persons in the industry guidelines associated with live electrical apparatus. Use of established cutting plan(s) relevant to the vegetation type Safety practices includes; the safe use of appropriate/specialised tools and equipment and may include safely accessing trees to install restraints/slings, removing tree limbs in a safe manner, clearing debris from the felling site to eliminate the occurrence of electrical incidents and reparation of risk assessment control measures that encompass job safety assessment. Excludes entry of persons, mobile plant, equipment, and/or specialised tools into to the safe approach distance (SAD) as defined. Work and zones is in compliance with relevant State or Territory regulatory agencies/bodies, local government legislation, Industry bi-partite body– Guidelines/Codes of Practices or other related requirements for safe work and access near live electrical and mechanical Apparatus Working safely up to the defined “safe working zone” near energised electrical apparatus (inc. electrical powerlines) for non-electrical worker/ordinary persons. Excludes any work that is or may be performed by other competent operatives within the defined “live work zone” Electricity supply infrastructure assets condition – sagging, swaying, ties, cross arms, poles, insulators, conductors, service wires, electrical apparatus/equipment, etc. Infrastructure constructions and excavations Safe approach distances zones/Safe Working Clearance Other areas which may need to be taken into consideration are: work permit(s) and/or access authorisation permits, technical standards and Industry Guidelines, rural applications, inclement weather, ground configuration and access – undulations, uneven ground, soft ground, damp, road construction, pavements, etc, feeder route plans and the use of technology and mathematical calculations Plant, equipment and specialised tools for use in electrical environments Vegetation control includes: site rehabilitation, horticultural vegetation cutting and pruning techniques to minimise regrowth - chemicals and physical cutting and pruning tools/equipment, concerns for vegetation type/species and significance – heritage, significant, urban/rural; vegetation fire prone areas and areas of particular significance. Use of technology and mathematical calculations The following constants and variables included in the Element/Performance Criteria in this unit are fully described in the Definitions Section 1 of this volume and form an integral part of the Range Statement of this unit: Appropriate and relevant persons (see Personnel) Appropriate authorities Appropriate work platform Assessing risk Assessment Authorisation Diagnostic, testing and restoration Documenting detail work events, record keeping and or storage of information Drawings and specifications Emergency Environmental and sustainable energy procedures Environmental legislation Environmental management documentation Established procedures Fall prevention Hazards Identifying hazards Inspect Legislation MSDS Notification OHS practices OHS issues Permits and/or permits to work Personnel Quality assurance systems Requirements Testing procedures Work clearance systems |
