Evaluating the training performance of wind technicians in Sri Lanka on critical rescue steps

Abstract

This study aims to assess the training performance of wind technician in Sri Lanka on critical rescue steps. Recognizing the inherent occupational hazards of working at heights within the wind energy sector, especially given the industry's rapid growth and the rising incidence of fall-related accidents (accounting for 44% of accidents in similar high-risk sectors), this research evaluates technician competency through structured rescue training. Utilizing the Global Wind Organization (GWO) Basic Safety Training standards, the research specifically investigates training retention and skill application among technicians. The research employed a Situational Judgment Test (SJT) and Job Knowledge Testing (JKT) to measure technician performance in executing prescribed rescue procedures. A purposive sample of 45 wind turbine technicians, who recently completed GWO- certified training, participated in the study. Data collection involved an online questionnaire designed to reflect real-world rescue scenarios encountered in onshore wind farms. Analysis revealed that approximately 58% of technicians demonstrated confidence in rescue device operation within the nacelle, whereas only 18% expressed similar confidence for external nacelle rescue tasks. Significant gaps in skill retention were evident, with skill decay notably higher among technicians lacking regular refresher training (p<0.05). Initial training, while comprehensive, was found insufficient alone, as performance assessments indicated a decline in critical rescue skills within six months of post-training. This research addresses a significant gap in existing literature by providing empirical evidence from Sri Lanka, an emerging market in wind energy. Results highlight the need for periodic skill assessments and refresher training as integral components of occupational health and safety protocols. Recommendations include structured refresher courses and regular performance evaluations to enhance the effectiveness of rescue training programs. The findings from this study not only inform local industry practices but also offer valuable insights applicable to global standards for technician safety and performance management in the wind energy sector.
