What PPE should ground personnel wear before guiding a helicopter?

• A. Hard hat and eye protection.
• B. Hearing protection and gloves.
• C. High-visibility clothing only.
• D. Helmet, eye protection, and high-visibility clothing.

Answer: (D)

When guiding a helicopter, you need protection for head, eyes, and clear visibility in a hazardous, fast-moving environment. A helmet provides impact protection against potential strikes from the helicopter structure, tools, or dropped objects. Eye protection guards against dust, wind-driven debris, and glare that can impair vision in windy rotor wash. High-visibility clothing makes you easily seen by the pilot and other crew members, which is crucial for maintaining safe distances and clear communications amid rotor downwash and dynamic operations. Together, these three protections reduce the main risks you face during helicopter guidance: head injuries, eye injuries, and being seen poorly by the operating crew. The other options miss one or more of these essential protections, so they don’t offer the same comprehensive safety coverage.
