Tackling OSHA’s Top 10 Citations: Q & A: Arc Flash Studies
Q: “When do you need to have an arc flash study conducted? Any tips on starting the process?”
A: There is no specific guideline, with the exception of NEC standards: the evaluation of electrical exposure risk, based on particular tasks and scope of work, is a requirement for injury prevention, and the burden rests with the employer.
If only ‘qualified workers’ are tasked with work on electrical systems, is an arc flash analysis necessary?
In theory and practice, ‘qualified workers’ have received training on hazard recognition and abatement, and would be familiar with proper protocol.
