What is the purpose of a safety railing in construction?

Answer: B — To prevent slips and falls

A safety railing in construction is primarily designed to prevent slips and falls, which is crucial for maintaining a safe working environment. Safety railings are installed at elevated areas, such as stairways, balconies, and rooftops, where there is a risk of workers or visitors accidentally stepping off an edge. By providing a physical barrier, safety railings effectively minimize the risk of accidents and injuries that could result from falls, which are among the most common hazards on construction sites. While aesthetics and other factors might play a role in some instances, the primary focus of safety railings is on safety and risk mitigation. Therefore, the key function that aligns with the purpose of a safety railing is to enhance protection for individuals working at heights, ensuring compliance with safety regulations and promoting a safe work culture.
