What is a requirement for all stairs at a construction site?

For all stairs at a construction site, it is required that at least one handrail be present. This requirement is crucial for ensuring safety as it provides support and stability for workers navigating the stairs. The presence of handrails significantly reduces the risk of falls, particularly in environments where workers are often managing tools and materials, and where the stairways may be used frequently under varying conditions. OSHA regulations specifically stipulate the need for handrails on stairways to enhance ergonomics and safety in the workplace.

The other options, while they may contribute to safety in specific contexts, do not fulfill the essential requirement mandated by OSHA for stair safety at construction sites. Anti-slip surfaces can offer an additional layer of safety, but the presence of a handrail is a fundamental safety requirement. The use of carpet or bright paint may improve visibility or comfort, but they are not universally required and do not address the immediate safety concern of providing support when using stairs.
