OSHA (Occupational Safety and Health Administration) does not have a specific standard that requires employers to conduct an arc flash analysis. However, as mentioned before, OSHA’s general duty clause requires employers to provide a workplace free from recognized hazards that are likely to cause death or serious physical harm. This means that employers must assess the hazards present in their workplace, including the potential for arc flash, and take steps to protect employees from those hazards.

Conducting an arc flash hazard analysis is an important part of evaluating the hazards in the workplace and identifying the necessary steps to protect employees. An arc flash analysis can be used to identify the electrical equipment and systems that have the potential to generate an arc flash hazard, determine the incident energy levels at specific locations within the electrical system, and develop and implement appropriate procedures and guidelines for employees who work on or near the electrical equipment.

While OSHA itself does not require an arc flash analysis, it’s important to note that OSHA standards are considered minimum requirements; it’s also worth noting that many employers choose to conduct an arc flash analysis as a best practice to ensure the safety of their employees, meet industry standards like NFPA 70E, compliance with OSHA, insurance or other regulatory requirements or to show due diligence in protecting their employees from hazards.

In summary, OSHA does not specifically require employers to conduct an arc flash analysis. Still, employers are required to assess and address workplace hazards. Many employers choose to conduct an arc flash analysis as a best practice and meet industry standards, regulatory compliance, or other requirements.
