While solar technology offers numerous benefits, such as renewable energy production, reduced carbon emissions and aiding in transitioning towards cleaner and renewable energy sources, it is not without its risks to those involved, especially to Solar Photovoltaic (PV) installers. Risk assessment in solar energy technology involves evaluating and quantifying potential risks, uncertainties, and hazards associated with the design, installation, operation, and maintenance of solar systems. When it comes to risk assessment for PV installers, there are several areas that need to be considered to ensure the safety of both the installers and the surrounding environment. These are not limited to: Site Evaluation, Electrical Hazards, Manual Handling, Working at height, Emergency procedures, Equipment and Tools. CONCEPT OF RISK ASSESSMENT IN SOLAR ENERGY TECHNOLOGY A key aspect in the implementation and operation of solar energy technology is the concept of risk assessment. In Mauritius this concept was introduced with the enactment of the Occupational Safety and Health Act (OSHA 2005). Its process comprises of five crucial steps namely: Planning, Hazard Identification, Evaluation, Control, Monitoring and Review. IMPORTANCE OF IDENTIFYING AND MITIGATING WORKPLACE RISKS Solar technology projects involve various tasks and activities that can be physically demanding and potentially hazardous. These tasks may include working at heights, handling heavy equipment and materials, exposure to electrical hazards, and working in extreme weather conditions amongst others. Without proper risk identification, workers may be exposed to these risks without adequate measures in place to protect them. Additionally, risk identification and mitigation in solar technology projects is crucial for the overall success and efficiency of the projects. Without proper risk management, projects 3 may face delays, cost overruns, and potential accidents or injuries. Moreover, risk identification and mitigation allow project managers to proactively plan and allocate resources to address potential risks in a timely manner. By identifying risks early on, project teams can develop strategies and implement controls to mitigate these risks, thereby reducing the likelihood of accidents or incidents occurring. Most importantly, it is a requirement by law and the OSHA 2005 stipulates that every employer shall suitably and sufficiently conduct a risk assessment within 30 days of the start of his project and shall act accordingly in the event of any insufficiencies. 4 CEB SOLAR INSTALLATION PROJECT OVERVIEW DESCRIPTION OF PROJECT It is the second-phase of the implementation of the Solar Farm PV Project, which involves the addition of a further capacity of 8 MW to Solar PV Farm of 2 MW at Henrietta which was commissioned in April 2019. The solar PV farm project aims to design, construct, and deploy an 8 MW solar photovoltaic (PV) farm by February 2023. The project involves an investment of $8 million and has been awarded to Bharat Heavy Electricals Limited (BHEL), a well-established company with experience in renewable energy projects. The solar PV farm consists of photovoltaic panels mounted on frames. The panels are strategically positioned across the designated site in Henrietta, considering factors such as sunlight availability and optimal energy generation. To ensure the successful completion of the project, key activities will include securing necessary permits and approvals, procuring high-quality solar panels and equipment, and conducting rigorous testing and commissioning. SCOPE OF PROJECT In the 2022-2023 budget, the Government reaffirmed its commitment to the transition to a green economy and has outlined its intention to take on board Investment by the CEB in an 8 MW solar PV farm at Henrietta by February 2023 to increase its capacity from 2 MW to 10 MW. CEB subsequently launched a tender for an 8MW ac solar PV farm project valued at $8 million. The CEB awarded the contract to Bharat Heavy Electricals Limited (BHEL), an Indian company specialized in power production, photovoltaics, and transmission solutions. The completion of this solar PV farm project will not only generate clean and sustainable electricity but also make a significant contribution to achieving regional sustainability goals. It will reduce reliance on fossil fuels, lower greenhouse gas emissions, and foster a more environmentally friendly energy infrastructure in Henrietta. However, the deadline for the project has been missed and no official date has been promulgated yet. 5 HAZARD IDENTIFICATION IDENTIFIED POTENTIAL HAZARDS ASSOCIATED WITH CEB SOLAR FARM PROJECT IDENTIFIED HAZARD TYPE OF HAZARD 01 Very slippery passage due to muddy terrain during rainfall Environmental 02 Lots of small scrap metal pieces with sharp edges scattered on site/ not properly disposed of Mechanical 03 Risk of falling in cable trenches more than 1m deep Mechanical 04 Broken PVs on site not properly disposed of Chemical 05 Exposure to weed whilst working under PV Mounting Structure may cause itchy skin Biological 06 Awkward positions and movements need to be adopted when working under PV mounting structures Ergonomic 07 Exposure to Extreme temperatures and solar radiation for long periods of time 08 Electric Shock 09 PV carton boxes left on site may catch fire when exposed to extreme heat.
