Sometimes called a “flashover”, an arc flash is part of an uncontrolled discharge (short circuit) resulting from a low-impedance connection through the air to the ground or another voltage phase in an electrical system.

Part of our dedication to your safety as well as compliance on your site(s) is identifying, labeling, and eliminating any arc flash hazards that may exist. Arc flash labeling is the responsibility of the employer and OSHA may cite and/or fine employers for failure to protect employees from its dangers.The NEC has created a list of electrical equipment that must be field marked with a warning label. It includes, but is not limited to, panel boards, motor controls, switchboards, and industrial controls.

Any modifications or changes to electrical equipment that change the data on the label will require an updated arc flash risk assessment and label according to the 2015 NFPA 70E standard.

At Young Electric, we believe all safety programs should be reviewed at least every three years and arc flash risk assessments every five years.
