What is the maximum height between landings for existing exit stairs according to RA 9514?

According to RA 9514, which pertains to the Fire Code of the Philippines, the maximum height between landings for existing exit stairs is indeed set at 3.66 meters. This requirement is crucial for safety and accessibility in buildings, ensuring that exit stairs are designed to facilitate the safe evacuation of occupants in case of an emergency. The specification of 3.66 meters is significant as it balances the need for structural feasibility with safety, allowing for manageable vertical travel without the need for excessive landings that could complicate or hinder evacuation paths.

Landings serve as rest points and are critical in providing stability and accessibility for individuals during an evacuation, particularly for those who may be physically challenged. By limiting the height between landings to this specific measurement, the code promotes a safer environment within buildings, thereby reducing risks associated with potential falls or difficulties encountered when navigating exit stairs during emergencies. Thus, the identification of 3.66 meters as the correct answer aligns with the safety protocols mandated by the fire code.
