The Top OSHA Green Job Hazards in Large Energy Transition Projects and How to Prevent Them

Solar panel installation workers

Solar Energy: Heights, Electrocution, and Hazardous Materials

Solar energy installation is a prime example of rapid growth paired with heightened risks. Workers often install photovoltaic panels on rooftops, exposing them to severe fall hazards. The U.S. Occupational Safety and Health Administration (OSHA) highlights falls as the leading cause of death and injury in solar jobs, coupled with the risk of electric shock when connecting systems to power grids. Workers are also sometimes exposed to hazardous materials, such as cadmium telluride, used in specific solar panel types.

Prevention involves implementing strict fall protection systems, such as harnesses and guardrails, comprehensive electrical safety training, and clear protocols for handling and disposing of hazardous materials. Regular training updates and compliance checks are essential to maintaining worker safety.

Wind Energy: Extreme Heights and Confined Spaces

The wind energy sector similarly poses significant occupational hazards, especially in the maintenance and construction of massive wind turbines. Technicians frequently work at extreme heights, facing potential falls, confined spaces inside turbine nacelles, and electrical hazards such as arc flashes. Proper management of these risks demands specialized safety training, rigorous enforcement of fall protection measures, and strict lockout/tagout procedures to isolate electrical systems during maintenance.

Hydrogen Energy: Flammability and Cryogenic Burns

Hydrogen, increasingly popular as a clean energy source, introduces its unique safety challenges. Its highly flammable nature means risks of fires and explosions, particularly when stored or transported under pressure or in liquid form. Additionally, handling liquid hydrogen can result in severe cryogenic burns. To mitigate these dangers, facilities must incorporate robust ventilation systems, explosion-proof equipment, and meticulous training on emergency responses and proper handling of hydrogen in various states.

Battery Storage: Thermal Runaway and Toxic Exposure

Battery storage, essential for stabilizing renewable energy supplies, brings risks like thermal runaway, in which batteries can dangerously overheat and ignite. Workers also risk exposure to toxic substances released during battery fires, such as hydrofluoric acid. Preventing these incidents requires stringent handling protocols, regular safety drills, specialized training on battery hazards, and effective fire detection and suppression systems within storage facilities.

Skills Gap: Training for Rapid Technological Change

Finally, an underlying hazard across all green sectors is the ongoing skills gap due to rapid technological advancements outpacing available training. Inadequate training can result in improper handling of advanced systems and increased risk of accidents. Bridging this gap requires industry-wide collaboration to develop standardized, comprehensive training programs tailored specifically to emerging renewable energy technologies and roles. Certification standards can also ensure that workers attain and maintain necessary competencies.
