The frequency of arc flash refresher training depends on several factors, such as the industry, regulatory requirements, and the specific hazards present in your workplace. In general, it’s recommended that workers receive arc flash refresher training at least annually but not to exceed three years to ensure that they are up-to-date on the latest safety procedures and regulations.

According to OSHA, training must be “regular and frequent,” and employers must verify that the employee understands the training. This means that employers are required to provide training at the time of the initial job assignment and regularly thereafter as necessary. If workers’ responsibilities or job duties change, they should also receive additional training.

NFPA 70E Standard for Electrical Safety in the Workplace recommends annual safety training for workers exposed to electrical hazards. The standard also states that retraining is necessary when the employee’s job changes, when the employee does not demonstrate safe electrical work practices, or when there is a new or increased electrical hazard in the workplace.

The IEEE 1584 standard for arc flash hazard calculations recommends that any worker exposed to an arc flash’s hazards should receive arc flash training at least every three years to maintain their understanding of the hazards and the necessary precautions.

It’s important to remember that the regulations and standards are the minimum requirements, and employers should strive to provide even more frequent and regular training to ensure the safety of their employees.

In summary, the frequency of the refresher training may vary. Still, in general, it’s advisable to have an annual or bi-annual review of the training and to update it as necessary. Additionally, if new equipment is introduced or changes are made, it’s essential to retrain all workers affected.
