On certain jobs, electricians can find themselves in an environment where the noise level exceeds the Occupational Safety and Health Administration’s (OSHA) time-weighted average limit of 90 decibels. A noise level of 90 decibels is approximately that of a lawn mower or subway train.
I’ve heard it all before. “What were they thinking when they wrote this standard? If I were them, this is how I would have done it.” When it comes to arc flash and electrical safety standards, complaints, armchair quarterbacking and second-guessing follow as soon as the latest edition comes out.
