Which are valid methods of approach during inspection?

• A. Scaffolding only
• B. Ladders, lifts, buckets, UBV, platforms, climbing
• C. Jumping with rope
• D. No access required

Answer: (B)

Safe, approved access to the bridge is essential for a thorough inspection, and that means using a range of methods that provide stable, controlled positioning for the inspector. Ladders are used for vertical access to higher sections when the distance is reasonable and stable; lifts or bucket trucks give elevated reach with guard rails and fall protection for hard-to-reach spots; an Under Bridge Vehicle (UBV) is a specialized platform that travels along the underside of the bridge to bring inspectors close to members and connections without climbing overhead; platforms offer a solid working surface for detailed observation and measurement; climbing is a legitimate method when it can be performed safely with proper fall protection and within the inspector’s qualifications. Together these options cover most inspection circumstances, from the tops of girders to the underside, while maintaining safety.

Options that rely on unsafe or unavailable access, like jumping with rope or proceeding with no access, are not acceptable for inspections because they do not provide controlled, reliable, and safe positioning for observing conditions.
