Question

12 what engineering control should warehouse management install at a blind intersection to protect pedestrians and ensure safety for all workers?

a. convex mirror
b. spotter
c. rearview mirror
d. motion sensors

Explanation:

Identify the safety requirement for a blind intersection

A blind intersection in a warehouse poses a high risk of collisions between pedestrians and industrial vehicles (like forklifts). To mitigate this risk, management needs to install a physical device that provides a wide field of view around corners.

Evaluate the given options

• A. Convex mirror: A convex mirror curves outward, reflecting a wide-angle view of the surrounding area. Installing it at a blind intersection allows both pedestrians and vehicle operators to see oncoming traffic around the corner, making it a standard engineering control for this scenario.
• B. Spotter: A spotter is a person, which is an administrative control rather than an installed engineering control.
• C. Rearview mirror: Rearview mirrors are mounted on vehicles, not installed at warehouse intersections.
• D. Motion sensors: While motion sensors can detect movement, they are typically used for automated systems or alarms rather than providing direct visual awareness for all workers at a standard blind intersection.

Select the best engineering control

The most direct, reliable, and standard engineering control installed at blind intersections to provide visual awareness is a convex mirror.

Answer:

• A. Convex mirror (Correct answer)
• B. Spotter
• C. Rearview mirror
• D. Motion sensors
