What preventive tool is used as a barrier at the point of operation to control hazards?

• A. Guard
• B. Shield
• C. Fence
• D. Barrier

Answer: (A)

Preventing exposure to hazards right at the machine’s working area is achieved with a guard. A guard is a physical barrier that surrounds or encloses the moving parts, keeping hands and other body parts out of the danger zone during operation. Guards come in various forms—fixed, interlocked, or adjustable—and may be designed to stop the machine if opened, ensuring protection even if someone attempts to reach in. Shields, fences, and generic barriers serve broader protective roles or different contexts, such as protecting from flying debris or restricting access to a area, but they don’t specifically address the immediate point-of-operation hazard as effectively as a guard.
