While water treatment and wastewater treatment facilities have sometimes been viewed as being outside the requirements of new arc flash standards, this perception is rapidly changing. Through the years, requirements for employee safety in the workplace have come under increasing government scrutiny. In particular, worker electrical safety is one of the latest and is still evolving. Although perceived as largely a liability issue, there are benefits to the w/ww industry of an electrical safety program that includes an arc flash hazard analysis. This paper presents some of the technical portions of the safety requirements and the potential benefits. The paper begins with an overview of the regulatory and technical requirements behind safe work electrical practices including a brief description of the applicable standards. The focus is on facility electrical equipment and the requirement for an arc flash hazard analysis. Some of the misconceptions associated with the analyses are presented. Specific issues from recent analyses are discussed with particular emphasis on w/ww facilities. Finally, the benefits of an electrical safety program are explained, including how an arc flash analysis can be applied to minimize liability, increase safety, protect equipment and processes, and minimize downtime. Includes tables, figures.
