8) Essential Knowledge and Associated Skills (EKAS): This describes the essential skills and knowledge and their level, required for this unit. Evidence shall show that knowledge has been acquired of working safely near live electrical apparatus as electrical worker. All knowledge and skills detailed in this unit should be contextualised to current industry practices and technologies. KS01-TEL16A ESI safe work practices near live electrical apparatus Evidence shall show an understanding of ESI safe work practices near live electrical apparatus to an extent indicated by the following aspects: T1 Electrical safety and principles encompassing: Hazards encountered in an electrical environment and safety procedures for dealing with them - types of hazards (hazards include electrical shock, fire from an electrical source, chemical hazards and fall hazards.), factors indicating general unsafe work practices and conditions, safety practices in the use of common tools and plant. Rescue techniques and first aid treatment of an electric shock victim - methods to rescue an electrical shock victim in contact with live equipment or conductors, accepted first aid treatment for burns, bleeding and shock, procedures for conducting EAR and CPR. Procedures for dealing with fires and hazardous chemicals associated with electrical equipment - selection and use of different types of equipment used to fight fires associated with electrical equipment, procedures for dealing with a fire associated with electrical equipment, procedures for dealing with PCBs. Basic circuit components and state the function of each - sources of electrical supply, control switches, types and functions of resistive consuming devices, basic circuit components symbols used in electrical diagrams. Connection of basic electrical circuits and measurement of circuit parameters - connection of components that make up a single-source single-load circuit, relationship between voltage and current in such circuits, consequences of a short-circuit and an open-circuit. Determining the voltage, current and resistance - calculation methods, measurement methods. Cable and conductor terminations to Australian/New Zealand standards - types of terminations, cable conductor preparation, prepare conductor for termination, termination method (conductor terminations include soldered and pressure types). T2 Transmission, distribution and rail systems encompassing: Relationship between the transmission, distribution and rail/tram system within an overall power system - different organisations responsible for generation, transmission, distribution and rail/tram and, how they correlate and their functions Characteristics of a transmission, a distribution and a rail system - principal components, typical voltage levels and methods of transmission and distribution including grid type transmission systems, radial, parallel and ring main feeders Relationship between an overhead and underground supply systems within an overall power system - advantages/disadvantages, applications and the basic steps for planning and installing an overhead and underground distribution system Single line drawings and layouts - drawings and layouts of transmission and distribution systems including, radial, parallel and ring main feeders and the HV equipment associated with substations T3 Fundamentals for working safely near live electrical apparatus encompassing: Standards, guidelines/codes of practice, State/Territory/local government legislation, supply authority regulations and or enterprise requirements including relevant certification and licensing, applicable to working safely up to the defined “safe working zone” near energised electrical apparatus (inc. electrical powerlines) for non-electrical worker Definitions of terminologies - ‘safe working zone’ ‘risk assessment’, ‘safe approach distances zones’, ‘safe working distances’.’ work permits’, access authorisation permits’, ‘Technical standards’ ‘isolation procedures’ and compliance requirements’ OHS policies and procedures for working safely - emergency response and First Aid procedures such as CPR, roles and responsibilities of employers, employees and other parties under OHS legislation, personal protective equipment, identifying hazards, assessing and controlling OHS risks, first aid procedures, duties of a safety observer, working at heights/confined spaces, permit to work systems and isolation procedures, safe application of different types of tools and equipment Operation of mobile plant and machinery (e.g. EWP) near live electrical apparatus Electricity supply infrastructure assets and voltages Techniques and precautions in undertaking different work functions and working safely up to the defined “safe working zone” near energised electrical apparatus (inc. electrical powerlines) for non-electrical worker - work functions that may be performed include, vegetation control, scaffolding, rigging, painting, and/or any other activity that requires working safely near live electrical apparatus by a non-electrical worker. |
