Which requirement applies to Vehicular Overhead Pivot Gates regarding rollers?

• A. All rollers should be covered or guarded unless they are 8+ feet above ground.
• B. Rollers must be exposed.
• C. Rollers may be left unguarded.
• D. Rollers must be replaced annually.

Answer: (A)

Moving parts on vehicular overhead pivot gates create crush and entanglement hazards, so guarding the rollers is required. The rule is that all rollers should be covered or guarded to prevent contact, with an exception only when a roller is eight feet or more above ground, where the risk of reaching it is minimal. This height-based allowance recognizes that guarding is most crucial where people or vehicles can reach the moving parts. The other ideas—rollers must be exposed, may be left unguarded, or must be replaced annually—don't align with the safety practice of preventing contact with moving components or with maintenance timing, which isn’t the focus of this requirement.
