Overhead Load Do not stand under a suspended load No access for unauthorized persons No naked flames or sparks Do not consume food or drink alcohol Do not smoking Safety boots or shoes must be worn Safety helmet must be worn Safety gloves must be worn Ensure good external ventilation at all times Safety glasses must be worn – General work not involving chemicals Read instructions Figure 1-Safety Signage 2.2 General 2.2.1 Every Worksite Presents Different Risks No two worksites are the same Before a solar installation begins, it’s essential for the installer to visit the site, identify the safety risks and develop specific plans for addressing them Plans should include: Equipment to be used for safe lifting and handling of solar panels Type and size of ladders and scaffolding if needed Fall protection for rooftop work Personal protective equipment for each installer 2.2.2 Trips and fall METHOD STATEMENT & RISKS ASSESSMENT Trips and falls are a common hazard of all construction jobs, including solar They can happen anywhere on the jobsite, especially off roofs or ladders Rooftop solar installations are especially hazardous because the work space diminishes as more panels are installed, increasing the risk of falls Safety measures for solar workers: Keep all work areas dry and clear of obstructions For fall distances of 1.8m or more, take one of three protective measures: install guardrails around ledges, sunroofs or skylights; use safety nets; or provide each employee with a body harness that is anchored to the rooftop to arrest a potential fall Cover holes on rooftops, including skylights, and on ground-level work surfaces 2.2.3 Solar Electrical Safety Solar electric (photovoltaic or PV) systems include several components that conduct electricity: the PV solar array, an inverter that converts the panel’s direct current to alternating current, and other essential system parts When any of these components are “live” with electricity generated by the sun’s energy, they can cause injuries associated with electric shock and arc-flash Even low-light conditions can create sufficient voltage to cause injury It’s also important to recognize that with PV systems, electricity comes from two sources: the utility company and the solar array that is absorbing the sun’s light Even when a building’s main breaker is shut off, the PV system will continue to produce power This makes isolating the power source more difficult, and requires extra caution on the part of the solar worker Safety measures for solar workers: Cover the solar array with an opaque sheet to “turn off” the sun’s light Treat the wiring coming from a solar PV array with the same caution as a utility power line Use a meter or circuit test device to ensure that all circuits are de-energized before working on them Lock out the power on systems that can be locked out Tag all circuits you’re working on at points where that equipment or circuit can be energized Never disconnect PV module connectors or other associated PV wiring when it is under load 2.2.4 Personal Protective Equipment Personal Protective Equipment is an essential part of every solar installation It’s the employer’s job to assess the workplace for hazards and provide the PPE deemed necessary for the employee’s safety Hard hats, gloves and steel-toed shoes with rubber soles are among the commonly required PPE for solar projects Employees are in turn responsible for using PPE in accordance with their employer’s instructions, maintaining it in a safe and reliable condition and requesting replacements when necessary Risk is part of running any business, but when it comes to an employee’s safety and health, risk should be avoided at all cost Proactive safety planning and its successful implementation on the job can help ensure that accidents don’t happen 2.2.5 Workforce leaders will be identified and will be responsible for raising Work authorizations 2.2.6 Vivablast on site supervisor will ensure that all requirements of the permit are met before commencing work METHOD STATEMENT & RISKS ASSESSMENT 2.2.7 Barriers and warning signs will be erected to cordon off the working area and non-authorized personnel allowed within the area Safety announcements will also be made before commencement and after completion of testing operations 2.2.8 Ensure any additional and any special safety equipment is identified and provided before actual operations commence (e.g eye wash stations, fire extinguishers, etc.) 2.3 Incident reporting 2.3.1 Introduction The client reporting and investigating procedures will take precedence in the event of an emergency METHOD STATEMENT & RISKS ASSESSMENT However, any incidents involving injury to Vivablast personnel, damage to equipment, or high all “Near Misses” will also be reported through Vivablast own reporting system 2.4 Hazard Severity Category Risk Assessment (Set-up, Carry out and pack up for Solar Plant Installation)

Installation METHOD STATEMENT & RISKS ASSESSMENT 3.1 Working Environment 3.1.1 The sites are exposed to the elements, being outside 3.1.2 All personnel will be required to wear appropriate PPE to protect them from adverse weather conditions and will be encouraged to use sunscreen as required 3.1.3 Works should cease in bad weather (persistent heavy rain, storm, high winds) as instructed by the site manager 3.2 Deliveries 3.2.1 The PV modules are delivered packaged in cardboard on pallets The modules will be marked and identifiable into power bands 3.2.2 The framework will be delivered strapped together in bundles secured to pallets 3.2.3 All other goods will be delivered to the site secured and removable via tail lift or onsite plant 3.2.4 Deliveries will be made in a timely manner to avoid any delays in installation 3.3 Distribution of Goods 3.3.1 PV modules should remain in their packaging until they are installed onto the support framework All packaging will be removed from site daily 3.3.2 The support framework and modules will need to be manually handled; protective gloves should be used for this 3.4 Storage: 3.4.1 Solar modules and framework will be protected from the elements and securely stored 3.4.2 PV module packaging should be kept dry to avoid collapse or compression of the packaging which might lead to damage to the modules or other equipment 3.4.3 All other equipment will be stored and secured until ready to be installed 3.5 Installation: 3.5.1 Gloves are to be worn by personnel whilst installing the framework to protect against sharp edges and hot / cold surfaces and final connections to complete works 3.5.2 Cloves should be worn when lifting and carrying modules to protect against sharp edges and corners 3.5.3 Modules are fixed to the mounting structures 3.5.4 PV modules only weigh approximately 15kg, but have a large wind uplift area and so should be handled by persons Works may need to be discontinued in adverse weather conditions 3.5.5 PV modules are made of glass, and are there for at risk of fracture or cracking Care of handling is to be a priority 3.5.6 Any damaged modules are to be wrapped and repackaged to avoid any further damage and risk of injury to persons They are to be clearly marked as damaged and returned to a storage area The site manager must be notified 3.5.7 Once a module is exposed to daylight, it generates a DC voltage 3.5.8 The modules are pre-wired with touch-proof connectors which isolate the current, but care must be taken not to interfere with or expose the terminals The voltage generated from one module is not considered dangerous (approximately 48 Volts) As the modules are connected to each other, the voltage increases and so does the risk of a harmful shock METHOD STATEMENT & RISKS ASSESSMENT 3.5.9 Before each module is fixed into the framework, a simple voltage check should be carried out to ensure that the module is operating 3.5.10 Any suspected faulty modules should be set aside for return 3.5.11 Protect the cables from stress (i.e ensure they are not trapped or trodden on) during installation as well as during storage prior to installation 3.5.12 All cables must be fitted with multi-contact shielded connectors at both ends before connection to the modules is made to prevent the possibility of personnel being exposed to bare live conductors 3.5.13 Keep the DC connectors dry where possible 3.5.14 As the modules are installed, they will be cabled up in series-connected ‘strings’ As each string is connected, a string voltage and polarity check will be carried out to ensure that all connections are sound, and findings recorded on a DC test sheet 3.5.15 All DC cables are to be labelled at both ends with the string number 3.5.16 All DC cables will be tested and logged on test sheets 3.6 Amenity 3.6.1 Work will only be undertaken between the hours of 07:00 and 17:00, to avoid noise at unreasonable hours 3.6.2 Care will be taken when loading and unloading vehicles, installing and dismantling scaffolding, etc to minimize noise impact 3.6.3 Waste: Contractors will remove all debris and rubbish from site, and dispose of it appropriately 3.6.4 Dust: The installation of PV panels on to the roof of the building is unlikely to result in a dust nuisance 3.7 Annex 1: Membrane rooftop mounting frame supports installation 3.7.1 Surface preparation – on
