• A. 3
• B. 4
• C. 6
• D. 5

Answer: (D)

In a high-angle rescue operation using a fixed brake bar rack, the minimum number of bars recommended is five. This configuration provides a balance between safety and control when lowering a rescuer or victim. Each bar contributes to the frictional resistance needed to control the descent speed, ensuring smooth operation under varying loads. Using five bars helps manage the potential for excessive speeds while allowing for fine-tuning of braking control. This is especially critical in a high-angle scenario, where maintaining control over the descent is paramount to prevent injury or additional hazards. Each additional bar helps increase the level of friction, which is vital given the complexities and unpredictability often present in high-angle environments. Thus, utilizing five bars not only adheres to safety protocols but also enhances the efficiency of the rescue operation.
