Arc flash protection is influenced by both PPE selection and equipment maintenance; if equipment is poorly maintained, PPE effectiveness may be limited.

• A. True
• B. False
• C. Not Applicable
• D. Sometimes

Answer: (A)

Arc flash protection depends on both wearing PPE that is rated for the expected incident energy and on keeping equipment in good condition. When equipment isn’t well maintained, several factors can increase the energy or exposure seen by the worker and/or degrade the PPE’s ability to protect. Faulty protective devices, degraded insulation, contaminated or damaged surfaces, and compromised enclosures can all raise the actual incident energy or expose live parts, meaning the PPE may be stressed beyond its rating or damaged before it can do its job. PPE is designed to withstand a certain level of energy, assuming the environment stays within that design, so neglecting maintenance can undermine its effectiveness. That’s why the statement is true.
