safety practices - working safely around electrical cables and infrastructure, including: effects of electric shock on the human body encompassing: shock currents burns risks of low voltage (LV), high voltage (HV) and high currents risk management and assessment of risk encompassing: principle and purpose of risk management processes for conducting a risk assessment hazards associated with electrical cables/conductors encompassing: electrical supply arrangements for isolation of circuits supply connected capacitance charge on cables isolated from supply consequences of damaged cables/conductors encompassing: accelerated deterioration of insulated cables, including damage to enclosures, serving, armours, sheathing and insulation without exposure of the conductors damage of exposing conductors with the likelihood of dangerous step voltage and touch voltage how a short circuit occurs and the resulting potential damage they cause risks and control measures associated with work in the vicinity of electrical cables and infrastructure the main features and purpose of an access permit system electrical isolation and types of permits issued for work in the vicinity of isolated cables scope of work permitted on an access permit safety observation procedures relevant industry standards for electrical isolation relevant WHS/OHS legislated requirements relevant workplace documentation relevant workplace policies and procedures. |
