What type of risk control option is it when requesting support for a ribbon-bridge crossing?

The choice of engineering control is correct in the context of requesting support for a ribbon-bridge crossing. Engineering controls involve using technology and physical modifications to mitigate hazards and risks. In this scenario, using a ribbon-bridge—designed to safely enable crossings over obstacles—is a technical solution that directly addresses the risk associated with moving personnel and equipment across an area where a traditional crossing may not be feasible or safe.

By implementing an engineering control, the risk of potential hazards, such as drowning or vehicle accidents when trying to cross an unsafe area, is effectively reduced. Such solutions are designed to minimize exposure to risks through structural means, which aligns with the principles of engineering control in risk management.

Other types of risk control options mentioned, like administrative controls, would typically involve changes in procedures or guidelines, while risk avoidance would mean completely eliminating the risk altogether, which is not applicable when utilizing a ribbon-bridge that still allows for crossing. Physical control might suggest measures that involve human intervention or personal protective gear, but here, the focus is on the engineered solution provided by the bridge itself.
