The request for an Engineer company with a ribbon-bridge is an example of which type of risk control option?

• A. Administrative control
• B. Engineering control
• C. Physical control
• D. Operational control

Answer: (B)

Engineering controls are physical changes or equipment designed to remove or reduce a hazard at its source. Requesting an Engineer company to provide a ribbon-bridge is selecting a technical solution that directly alters the environment to make the crossing safer. It lowers risk by introducing a proven, engineered crossing system rather than relying solely on procedures, training, or how the task is carried out. Administrative controls would involve policies or training; physical controls are barriers or protective devices; operational controls relate to how the work is executed without changing the environment or equipment. The ribbon-bridge is a specific engineered solution that enables a safer crossing over a water obstacle, reducing exposure to hazards.
