How long should the protection of a bridge strike be maintained?

The duration of protection for a bridge strike is crucial for maintaining safety and ensuring proper procedures are followed. The correct answer highlights the requirement for the bridge to be certified by a DUAL Qualified individual. This is important because a DUAL Qualified individual has the necessary training and expertise to assess the bridge’s structural integrity after a strike. Until this certification is obtained, the bridge may still pose a risk to rail operations and safety.

Other choices may suggest varying degrees of urgency or oversight, but only the certification by a qualified individual ensures that the bridge has been thoroughly evaluated. Rather than artificially limiting the timeframe for protection or relying on scheduled inspections, which may not coincide with immediate risk management needs, this answer underscores the importance of a qualified assessment to ensure safety before resuming normal operations.
