Explanation
The question pertains to the role of guards in a workplace, particularly in relation to machinery and worker safety. Guards are devices or structures designed to protect workers from hazards associated with machinery. The options provided suggest different functions of guards:1. "Detects contact with the worker" implies a guard that senses when a worker is in contact or close to the machinery. This is more characteristic of safety sensors or detection systems rather than guards.2. "Places a physical barrier between the worker and machine" describes the primary function of a guard. Guards are often physical barriers that prevent workers from coming into direct contact with dangerous parts of machinery.3. "Monitors for worker contact" is similar to the first option and implies a monitoring or detection role, which is not the primary function of a guard.4. "Acts as a warning sign for workers" suggests a passive role in alerting workers to potential hazards. While warning signs are important, they do not physically intervene to prevent contact with machinery, which is a key function of guards.Therefore, the most accurate description of what guards do to protect the worker is placing a physical barrier between the worker and the machine. This barrier prevents direct contact with moving parts, hot surfaces, electrical components, or other hazards associated with the machinery.
