Who is qualified to perform an arc flash study?Īn arc flash study is a complex engineering evaluation that requires specialized knowledge and experience in electrical power systems, protective device coordination, and arc flash hazard analysis. Employers should work with qualified professionals to determine if an arc flash study is necessary for their specific electrical system and to ensure compliance with relevant regulations and standards. While no federal law specifically requires an arc flash study, several regulations and standards may indirectly require it as part of an overall electrical safety program. The NEC includes requirements for equipment to be installed and maintained safely and for protective devices to be coordinated to reduce the likelihood and severity of arc flash incidents. NEC: The National Electrical Code (NEC) provides guidelines for installing electrical equipment and systems. NFPA 70E recommends conducting an arc flash hazard analysis to identify hazards and risks associated with electrical equipment and to develop appropriate safety measures. NFPA 70E: The National Fire Protection Association (NFPA) 70E Standard for Electrical Safety in the Workplace provides guidelines for protecting workers from electrical hazards, including arc flash hazards. An arc flash study can help identify hazards and risks associated with electrical equipment and help develop safe work practices and procedures. OSHA regulations related to electrical safety (.303-308) include requirements for electrical equipment to be installed and maintained in a safe condition and for employees to be trained in safe work practices. OSHA regulations: The Occupational Safety and Health Administration (OSHA) requires employers to provide a safe working environment for their employees. However, some regulations and standards may indirectly require an arc flash study as part of an overall electrical safety program. In the United States, no federal law specifically requires an arc flash study. Visit our Arc Flash Analysis/Study Training Course Page

Therefore, working with a qualified engineer or technician ensures the arc flash study is conducted correctly and complies with relevant overall occupational health and safety standards and regulations. Overall, an arc flash study is an important component of an electrical safety program and helps to ensure that workers are protected from the risks associated with arc flash incidents such as electric shock. Selection of appropriate PPE: Based on the calculated incident energy levels, the arc flash study should recommend the proper level of personal protective equipment (PPE) required for workers.Ĭoordination of protective devices: The arc flash study should coordinate protective devices, such as fuses, circuit breakers, and relays, to ensure that they function correctly and in a coordinated manner to reduce the likelihood and severity of an arc flash incident.ĭocumentation of study results: The arc flash study should document the results of the analysis, including the identified hazards, the incident energy levels, the recommended PPE, and any recommendations for equipment upgrades or modifications. Identification of potential workplace hazards: The arc flash study should identify potential and associated risks, such as the likelihood of an arc flash occurrence and the severity of the possible injury.Ĭalculation of incident energy: The arc flash study should calculate the incident energy levels at each point in the electrical system, which is the amount of energy that could be released during an arc flash incident. However, several vital factors and standards should be considered when conducting an arc flash study.Ĭompliance with safety standards: The arc flash study must comply with relevant safety standards and regulations, such as those set by the Occupational Safety and Health Administration (OSHA), the National Fire Protection Association (NFPA), and the Institute of Electrical and Electronics Engineers (IEEE).Ĭomprehensive analysis of the electrical system: The arc flash study should include a comprehensive analysis of the electrical system, including equipment such as switchgear, circuit breakers, motor control centers, and transformers. Arc flash study requirements vary depending on the jurisdiction and the specific electrical system being evaluated.
