Abstracts:Recent advances in battery risk assessment methodology can be difficult to understand and apply. This article presents a series of example risk assessments on real battery systems of different sizes and chemistries. We walk through work planning and the control process for energized work on batteries, from the initial work order to project completion. We elaborate on how different engineering controls, such as a ground fault detector and indicator, impact battery risk assessment and what to do when you do not know whether they are functioning correctly. We present case studies in several types of battery systems, including lead–acid, lithium-ion, and vanadium redox. The article concludes with an assessment of training, policy, and code shortfalls that may have contributed to past accidents.

Abstracts:This article examines Abracopel’s initiatives to improve electrical safety in Brazil. Founded in 2005 to address the high number of electrical accidents, Abracopel has established itself as an essential entity in promoting electrical safety. The organization is involved in several projects, including the publication of a Statistical Yearbook of Electrical Origin Accidents, the Electricity Safety Perception Survey, and a “Snapshot of Brazilian Residential and Commercial Electrical Installations.” These efforts highlight the prevailing risks and the necessity for better public policies and safety practices. One of Abracopel’s strategic pillars includes the Essay, Drawing, and Video Competition, targeting students across Brazil to increase awareness about electrical safety. This project, celebrating 12 years in 2023, engages students in creating materials on electrical risks and prevention methods. The competition has shown remarkable reach and impact, with the number of participants growing. Each participant is believed to influence several other people in their communities. This article underscores the vital role of educational initiatives in shaping safer attitudes and practices using electricity. Furthermore, this project aligns with the two United Nations’ Sustainable Development Goals (SDG). The article concludes that such initiatives are highly efficient in fostering a culture of safety and awareness, thereby reducing electrical accidents in society.

Abstracts:This paper describes how a commonly used machine risk assessment methodology was ‘slightly’ modified for use to evaluate common tasks associated with electrical equipment. The method can be used to provide a hazard rating number (HRN) for a specific electrical task performed on a specific piece of electrical equipment. The author has applied this methodology to an entire site’s electrical distribution system from the incoming utility, on site power distribution, 24kV to 480V or 2400V substations, switchgear, and motor control centers. The method considers the effectiveness of the site’s maintenance program, health and age of the equipment, active / passive controls, engineering controls, use of procedures, and arc flash energies. This paper will present specific examples for the ‘as-found’ condition and then explore how mitigation methods affect the HRN score. The results can be used for decision making on how to spend capital to improve safety and prevent electrical injuries.
