At what height must an employer have a guardrail erected for a temporary work area?

• A. 2.5 m (8 ft)
• B. 3.0 m (10 ft)
• C. 4.0 m (12 ft)
• D. 1.5 m (5 ft)

Answer: (B)

According to safety regulations, a guardrail must be installed for temporary work areas at a height of 3.0 meters (10 feet). This height is established to ensure maximum safety for workers and to minimize the risk of falls from elevated surfaces. The 3.0-meter (10-foot) requirement is aligned with industry standards that aim to protect individuals who are working at considerable heights, addressing concerns such as fall risks and injury prevention.

Establishing a guardrail at this specified height creates a physical barrier to prevent workers from accidentally slipping or falling over the edge, thus promoting a safer working environment. It's important to follow these regulations not only for compliance but also for the overall safety and well-being of all personnel involved in the work. Proper height specifications for guardrails are a crucial element observed in various safety codes and standards across different regions or industries.
