What is the maximum height of a stair rise according to PD 1096?

According to PD 1096, which is a set of building laws in the Philippines, the maximum height of a stair rise is stipulated to ensure safety and accessibility in building design. The correct answer reflects the maximum rise of 200 mm. This specification is critical as it establishes a uniform and manageable height for stair treads, which promotes safe navigation up and down stairs, reducing the risk of tripping or falling.

Standards like these are important in construction codes, as they help architects and builders create spaces that are user-friendly for individuals of varying physical abilities, including the elderly and those with disabilities. Consistency in stair rise height also facilitates the design of buildings that comply with universal accessibility guidelines.

While the other options suggest lower maximum heights, they do not align with the regulations established by PD 1096, which recognizes the practical balance between safety and structural design in building stairways. This knowledge is particularly significant for those involved in construction and design, as adherence to such standards is crucial for both compliance and the overall wellbeing of building occupants.
