Solar PV Technology : Health & Safety

  1. 1. Safety, Health & Environment (SHE) Solar PV Technology General Overview from Vinod Jyothikumar, PhD EHS Consultant : vjkehs@gmail.com
  2. 2. Health and Safety Concerns of Photovoltaic Solar Panels Materials used in photovoltaics solar panels  The basic building block of a photovoltaic solar system is the solar cell. Solar cells are solid state, semiconductor devices that convert sunlight into electricity.  Typically a number of individual cells are connected together to form modules, or solar panels.  In order to provide electrical insulation and protect against environmental corrosion, the solar cells are encased in a transparent material referred to as an encapsulant.  To provide structural integrity the solar cells are mounted on top of a rigid flat surface or substrate. A transparent cover film, commonly glass, further protects these components from the elements. Courtesy of the U.S. Department of Energy
  3. 3. Health and Safety Concerns of Photovoltaic Solar Panels Simplified Photovoltaic Solar Panel Life Cycle Exposures to harmful dust, contaminated soil, etc. Strong fumes, by-products, inhalation of kerf dust, a byproduct of silicon etc. Exposures to heavy metal poisoning e.g. Lead soldering.
  4. 4. Health and Safety Concerns of Photovoltaic Solar Panels Major Hazards in PV Manufacturing x-Si • HF acid burns SiH4 fires/explosions Pb solder / module disposal a-Si • SiH4 fires/explosion s CdTe • Cd toxicity, carcinogenicity, module disposal CIS, CGS • H2Se toxicity, module disposal GaAs • AsH3 toxicity, As carcinogenicity, H2 flammability, module disposal
  5. 5. Occupational health and safety (OH&S) Management Overview Occupational health and safety (OH&S) management system standard for Industries Safety Policies Safety directives Process Design Standard Safety & Health Manuals Safety & Health Trainings Internal Certification Scheme The Three C’s of the Solar-PV Technology HSE Program • Conformance: Meets the requirements (Implements the “shalls”) • Consistency: Various elements inter-related (i.e., Significant aspects reflected in emergency planning, etc.) • Continual improvement: Mechanisms are in place to improve the O&SH and organizational performance, supported by management commitment and support
  6. 6. Why Occupational health and safety (OH&S) management system for PV Technology ? Lessons Learned from Accidents  No formal hazard evaluation and risk assessment had been completed to characterize the potential danger of the research activity and to plan for the worst-case scenario  End user sought peer advice, Fire responders needs to be informed about the operation process.  No policy was in place to prompt the end users to seek SME advice or evaluation of operational activities.

  7. 7. EHS performance management system. Continual Improvement Cycle Plan-Do-Check-Act
  8. 8. Highlights of the elements proposed for Solar PV Technology-Safety Management System Oversight and Leadership team • Functions as the corporate sponsor for the safety management system. • Ensure that resources are available for performing necessary work. • Provide support and guidance to element leadership team. • Helps element leadership teams to gain support from all stakeholders and where necessary to remove obstacles from their path. • Helps to prioritize activities such that change impact to the lab safety are managed and where possible accidents are minimized. Establish the safety culture vision All element standards clearly defined Responsibilities and resources allocated Training provided to all personnel Activities documented Internal controls developed and activated Sustainment process developed and activated Performance management
  9. 9. Safety TOOLS for assessing PV Technology
  10. 10. PCR-SIT Profile Analysis-Internal Audits It gives a bird’s eye view of the whole PV Technology process from many different angles that Executive Leadership Team wants to check and keep a track of while contemplating on a certain idea/plan. GOAL –Perfect Hexagon P-Policy includes: Biosafety , Radiation safety, Chemical Safety, LASER Safety Programs and more.. C-Training &Certification of the employees based on Occupational Health and Safety Management System R-Regulations : (OHSAS) 18001:2007 and OHSAS 18002:2000 S-Standard Operating Procedure followed in the PV Technology process cycle. I-Inventory Management e.g. Hazardous chemicals used during PV technology etc. T-Technology: Risk Analysis for the new tools / instruments used for PV technology
  11. 11. Drivers for Executing PV Technology-Safety Management System Higher trust and credibility among all lab members Reduced health care treatment cost Identify gaps and tighten up procedures Fewer incidents and injuries Standardize practices Clearer understanding of roles & responsibilities
  12. 12. Conclusion Effectiveness of policies Excellence in leadership and management Total quality by participation Utilization of Safety Contributions Comprehensive and widening OSH both as a specific process and embedded in the work system and processes OSH culture To reiterate the main ideas, we conclude that generally, end users- could follow, utilize and contribute practically in terms of all key starting points
