8) This describes the essential skills and knowledge and their level, required for this unit. Evidence shall show that knowledge has been acquired of safe working practices and installing aerial communication cables. All knowledge and skills detailed in this unit should be contextualised to current industry practices and technologies. KS01-EF113A Telecommunication underground cabling requirements and techniques Evidence shall show an understanding of telecommunication underground cabling, applying safe working practices and relevant Standards, Codes and Regulations to an extent indicated by the following aspects: T1. Hazards and control measures in underground cabling working environment Risk management and assessment of risk: Principle and purpose of risk management, and Processes for conducting a risk assessment Hazards associated with low-voltage, extra-low voltage and high-currents: Parts of an electronic systems and equipment that operate at low-voltage and extra-low voltage, Parts of an electronic systems and equipment where high-currents are likely. Risks and control measures associated with high-voltage: Parts of an electronic systems and equipment that operate at high-voltage, The terms ‘touch voltage’, ‘step voltage’, ‘induced voltage’ and ‘creepage’ as they relate to the hazards of high-voltage, and Control measures used for dealing with the hazards of high-voltage. Risks and control measures associated with low voltage: Risks associated with installation, fault finding, maintenance and repair. Control measures before, while and after working on electronic systems or equipment Isolation and tagging-off procedures. Risks and restrictions in working live. Control measures for working live.
