Which of the following is a common method to prevent falls in the workplace?

Providing stair railings is a highly effective method for preventing falls in the workplace, particularly in environments where staircases are frequently used. Stair railings serve as a physical barrier that can help individuals maintain their balance and reduce the risk of slipping or losing footing while ascending or descending stairs. This preventive measure is crucial, as falls are often a leading cause of workplace injuries, especially in construction sites or multi-level workplaces.

In addition to providing support and stability, stair railings should be designed and maintained properly, ensuring they are at the appropriate height and securely anchored to withstand pressure. This contributes to a safer workplace environment and promotes adherence to safety regulations that require such safety features.

Other methods mentioned, while beneficial in their contexts, do not address the specific hazards associated with stair safety as comprehensively as installing stair railings does. For example, safety nets may be useful in scaffolding situations, warning signs can raise awareness of potential hazards but do not physically prevent falls, and adequate lighting is essential for visibility but does not provide support. Therefore, providing stair railings stands out as a direct and effective means to mitigate the risk of falls associated with stair use.
