What are the minimum riser height and maximum tread width, in inches, for fixed industrial steps recommended by OSHA and ANSI?

The correct answer specifies that the minimum riser height is 6 ½ inches and the maximum tread width is 11 inches, which aligns with the guidelines established by OSHA and ANSI for fixed industrial steps. This particular measurement is significant because it ensures safety and accessibility for workers using these steps.

The riser height of 6 ½ inches is critical as it strikes a balance between being high enough to provide structural design integrity while low enough to minimize the risk of tripping or falling. The maximum tread width of 11 inches is advantageous for providing adequate foot support and reducing slips as individuals navigate the stairs. These specifications are designed to enhance user safety in industrial environments where proper design can prevent accidents and injuries.

Being aware of these measurements is essential for compliance with safety regulations and for promoting a safe working environment. Therefore, selecting this combination reflects a sound understanding of safety standards upheld in the industry.
