The Hierarchy of Control Measures offers a systematic process for reducing the likelihood that an incident occurs. The hierarchy of risk control methods has been a common theme in the safety world and is in no way a new concept, but as part of NFPA 70E, the hierarchy was moved from being an informational note to the standard’s mandatory text. NFPA 70E (2018): Hierarchy of Risk Controls in the Spotlight While not officially representative of the regulatory code, the Occupational Safety and Health Administration (OSHA) considers the NFPA 70E standard a “recognized industry practice” and has levied fines to companies that haven’t protected their employees when arc flash accidents have occurred. Written as a guide for employers, workers, and anyone looking to understand safe operating practices in the electrical world, NFPA 70E is the prevailing source for best practices and procedures, with previous editions guiding future regulations. Updated every three years, the National Fire Protection Agency’s standard for electrical workplace safety, NFPA 70E, went into effect in August 2018. ![]()
