Massachusetts Construction Supervisor License (CSL) Practice Test

What is the primary concern addressed in IRC section R311.7 regarding stairways?

1. Energy efficiency standards for stair lighting.

2. Stability and safety of the stair construction.

3. Accessibility requirements for disabled persons.

4. Design aesthetics of stair railings.

The correct answer is: Stability and safety of the stair construction.

The primary concern addressed in IRC section R311.7 regarding stairways is focused on the stability and safety of the stair construction. This section outlines specific requirements for the dimensions of stairs, including tread depth, riser height, and the need for handrails, to ensure that stairways are safe to use. These provisions are crucial for preventing accidents such as falls, which can result from improperly constructed stairs. In this context, the section's emphasis on proper construction practices highlights the importance of maintaining uniformity and stability in stairs, making them safe for all users. By focusing on factors such as load-bearing capacity and the secure attachment of handrails, the code aims to protect individuals using the stairs from potential injuries. Other options may encompass important aspects of building codes and construction practices but do not directly relate to the primary concerns addressed in this specific IRC section. Energy efficiency, accessibility, and design aesthetics are addressed in different sections of the code or through separate regulations, illustrating the multifaceted nature of building safety and compliance, but they do not capture the main intent of R311.7 which is centered on the structural integrity and safety of stairways.
