What is the minimum height at which a guardrail is required to be installed on construction sites?

• A. 36 inches from the walking/working surface
• B. 30 inches from the walking/working surface
• C. 42 inches from the walking/working surface
• D. 48 inches from the walking/working surface

Answer: (C)

A guardrail is an essential safety feature designed to prevent falls and protect workers on construction sites. The minimum height requirement for guardrails is set at 42 inches from the walking or working surface. This height is recommended because it provides a sufficient barrier to prevent workers from falling off elevated surfaces, particularly in environments that may not have other forms of fall protection. The 42-inch height is part of safety regulations and standards outlined by organizations such as OSHA (Occupational Safety and Health Administration) and is widely adopted in construction safety practices. It ensures that the guardrail is high enough to deter individuals from inadvertently leaning over or falling through open edges or platforms. The specific height of 42 inches is based on ergonomic assessments and industry practices designed to maximize safety for workers, who may be operating in various environments that pose risks of falls. This height is designed to accommodate a broad range of worker heights while providing adequate protection.
