What is the maximum angle for installing stairs according to regulation?

The maximum angle for installing stairs according to regulation is 40 degrees. This angle is established to ensure that stairways are safely designed for use, providing a balance between accessibility and stability. Steeper stairs can increase the risk of slips and falls, making a 40-degree angle a practical limit for safe construction and usability.

In the context of fire alarm systems and how they interrelate with building code compliance, it is vital to consider accessibility during emergencies. Steeper stair angles can impede egress during a fire situation, so adhering to the 40-degree maximum ensures that all building occupants can evacuate safely and efficiently.

Understanding the importance of this regulation helps reinforce the overall safety strategy in building design, particularly in environments subject to fire hazards where quick evacuation is crucial.
