According to OSHA, what personal protective equipment (PPE) is required for lift operators?

The correct choice emphasizes the comprehensive protection required for lift operators, which is critical for ensuring safety while operating boom and scissor lifts. Hard hats are necessary to protect against head injuries from falling objects, which is a common risk in construction and maintenance environments where these lifts are often used. Safety glasses are essential for eye protection against debris, dust, or other hazards that may arise during operation. Harnesses are particularly important when working at height, as they provide fall protection, which is vital for preventing serious injuries or fatalities.

In contrast to this comprehensive protection, the other options do not cover the same level of safety requirements expected for lift operators. Gloves and knee pads, while useful for certain jobs, do not address the specific hazards associated with operating lifts. Ear protection and masks focus more on hearing and respiratory hazards, which may not be as relevant for lift operation. Steel-toed boots are beneficial for foot protection, but they alone do not provide the full range of protections necessary for lift operation. Thus, the combination of hard hats, safety glasses, and harnesses reflects an understanding of the specific risks involved with operating lifts in various environments.
