HRC stands for Hazard Risk Category and is used most directly to determine what?

• A. PPE level
• B. Arc current rating
• C. Voltage class
• D. Color of PPE

Answer: (A)

HRC, or Hazard Risk Category, is about choosing the level of arc-flash PPE you must wear. It ties directly to the expected incident energy and the protection you need, so the higher the risk, the higher the PPE level you select. This ensures your clothing, gloves, face protection, and any other gear can withstand the arc energy you might be exposed to.

It doesn’t set the arc current rating of equipment, which depends on fault current and protective devices; it doesn’t define voltage class, which is a property of the electrical system itself; and it isn’t about the color of PPE, which is cosmetic. The main purpose of HRC is to guide the selection of the appropriate PPE level for protection.
