The tools you use are also important, and if used properly can contribute to the quality of the work you perform and prevent unnecessary risks. Every Field Contractor must comply with the nbn Code of Conduct whenever they are conducting an installation For more information, see Nbn code of conduct. 2.1 Health, safety, and environment (HSE) This document provides guidance to assist Field Contractors to exercise due diligence and safe work practices. Field Contractors are expected to comply with their HSE management systems. The safety-related information in this document is intended as guidance only and should not be relied upon. Companies engaged to undertake nbn work must satisfy themselves that they understand the risks associated with their work and their controls. 2.2 Important HSE symbols Error! Reference source not found.The following table shows the symbols displayed in this guide whenever there a re potential hazards when performing an installation. Symbol Description Electrical Hazard The nbn network is often located near electrical circuits in Premises and on or near the electrical distribution network. Contact with electricity can cause serious injury or death. Safe work practices must always control the risk of contact with electricity. This includes maintaining safe distances from live circuits, isolation of power when working on or near live circuits, having required training, licences and registrations, and complying with relevant standards. If a pit is within an Earth Potential Rise (EPR) zone, such as within 15 m of a high voltage transformer or switch, then there is a possibility that a person may receive an electric shock. This can occur when the person is working on a metal cable or fittings attached to the cable while they are also in contact with the local surrounding within the EPR zone. Whilst it is preferable not to locate assets within an EPR zone, if this cannot be avoided then appropriate HSE and PPE procedures should be implemented when working in the EPR zone. Asbestos Asbestos is a hazardous substance. Legislation determines that particular processes must be followed when working with asbestos or asbestos containing materials. © 2018 nbn co limited | ABN 86 136 533 741 Page 11 of 47 Uncontrolled when printed nbn-Confidential: Commercial HFC Service Assurance Field Guide P0223-14-322 | Rev 2.0 Symbol Description Personal Protective Equipment Personal Protective Equipment (PPE) is clothing and equipment used to offer protection against hazards. PPE should never be treated as a substitute for safe behaviour and following working practices, but as a last line of defence. Examples of PPE include: Eye goggles Covered footwear Hi-visibility vests Sunglasses Sunscreen P2 face mask Gloves Hearing protection Working at Heights Working on a construction site. As a general comment, HSE laws, regulations, standards, codes of practice, etc. require a range of risk control measures when working at heights (e.g. safe work platforms, fall arrest devices, etc). Confined Space Working in confined space or hazardous atmosphere. As a general comment, HSE laws, regulations, standards, codes of practice, etc. require a range of risk control measures when working in confined spaces (e.g. work permits, training, atmospheric monitoring, restriction of ignition sources, working in teams rather than alone, etc). 2.3 Risk management When performing field activities as part of HFC service restoration, ensure that you take the following hazards into consideration: Services such as electricity, gas, water and rail Fire Radiation Inadequate egress Working alone Working at heights Dangerous goods and hazardous substances, including asbestos Confined Space Machinery Hazardous Atmosphere Open trenches associated with excavations Mobile plant such as vehicles Flora and fauna Manual handling © 2018 nbn co limited | ABN 86 136 533 741 Page 12 of 47 Uncontrolled when printed nbn-Confidential: Commercial HFC Service Assurance Field Guide P0223-14-322 | Rev 2.0 Working environment Slippery or uneven work surfaces All active equipment that remains energised poses a risk of electric shock to any worker. Consider the electrical hazards highlighted in the following tableError! Reference source not found.. 2.3.1 Electrical Hazards Isolation of power (i.e. turning all power off) This is the most effective way to minimise electrical risks. Consider power isolation for the duration of work in roof and sub-floor spaces, consistent with your company’s safe systems of work and with the approval of the End User. Effective isolation should involve physically turning all power off (at the switchboard), attaching a completed Danger Tag, physical locking of the main switch or switchboard enclosure, and positively proving (i.e. testing) electrical power is isolated. Additionally, consider power isolation for drilling into walls where electrical services exist as per your company’s safe systems of work. Residual electrical risks These may still be present even after power isolation. For example, power in solar panels and associated cabling, and the electrical lead-in to the Premises, which remains live between the power pole/pillar and the back of the switchboard. Electrical circuit breakers or fuses Ensure that they are clearly and correctly labelled and fitted or capable of being fitted with a lockout device to isolate every source of electrical energy from the circuit. Double insulation and earthing All 240 V electrical cables are double insulated and earthed in accordance with applicable network standards and Error! Reference source not found.. Labelling All electrical equipment is clearly and correctly labelled. Wear and abrasions All cables are free of wear and abrasions. Safety and security All power sockets are securely fastened, fit for purpose, and free from wear or damage. Metallic enclosures Ensure that metallic enclosures with a 240 V Power Outlet are earthed. Use a non-contact voltage indicator to ensure metallic enclosures are not live before use. Adherence to standards All correct power cable to communications cable separations are maintained according to Error! Reference source not found. and Error!

You must review these hazards and determine their relevance and, if appropriate, manage the risk via your own risk management process, which should refer to relevant legislation, codes of practice, industry information and any guidance materials provided by nbn. 2.4 Reporting hazards and incidents All hazards and incidents (including near misses) occurring or identified during any work on behalf of nbn must be reported according to the process and timing defined by nbn under the contract or nbn policy. Where a hazard presents an immediate risk, you should stop work, or implement an immediate interim control measure and contact your Workforce Management Centre (WMC) for guidance on further responses, including permanent control of the hazard. Where required, nbn can facilitate communication of relevant information arising from hazard and incident reports to the End User. 2.5 Training and competency As part of the evaluation process, nbn takes into account the Field Contractor’s processes for ensuring training and competency of Field Contractor. For example, legislative requirements, risk based training and industry training are considered relevant. Contracted companies are expected to comply with their HSE management system’s training and competency requirements. The Field Contractor must adhere to any induction, training, or competency requirements of the building within which they are working. Field Contractors undertaking work activities on Premises require the following training and competency as a minimum: Open cabler’s registration with an ACMA accredited registrar as per the Error! Reference source not found. White card – CPCCOHS1001A Work Safely in the Construction Industry qualification Note: In addition to the above industry qualification and competency requirements, all Field Contractors must register for, and complete, the mandatory online training courses on the nbn enAble™ accreditation portal. Where Field Contractors are undertaking specific tasks associated with drop work or on-premises work, additional training and competency may be required. For example, training and licensing in the operation of elevate platforms. © 2018 nbn co limited | ABN 86 136 533 741 Page 14 of 47 Uncontrolled when printed nbn-Confidential: Commercial HFC Service Assurance Field Guide P0223-14-322 | Rev 2.0 3 About nbn HFC service installations Figure 1 displays the nbn HFC network trail from the CMTS through to the End User Premises (EUP) with the network boundary for: A standard nbn HFC service terminated at the nbn NTD.
