Which term is defined as a barrier with a synonym 'Guardrail' among safety terms?

• A. Handrail
• B. Guardrail
• C. Barrier
• D. Fence

Answer: (A)

Barrier is the general safety term for a structure that blocks or restricts access to a hazard. Guardrail is a specific type of barrier installed along edges to prevent falls or guide movement, so it fits as an example within the broader category. Handrail, by contrast, is a rail for hand support on stairs or ramps and isn’t a barrier that blocks access. Fence is another enclosure type, but it isn’t the standard term used for the safety category that includes guardrails. Thus, Barrier best matches the definition of a barrier with guardrail as a common synonym.
