What is the maximum height of the threshold for exit doors specified by RA 9514?

The correct specification for the maximum height of the threshold for exit doors according to Republic Act No. 9514, also known as the Fire Code of the Philippines, is indeed 13 mm. This height is established to ensure accessibility and safety during emergencies when buildings may need to be evacuated quickly. A threshold height of 13 mm minimizes the risk of tripping and allows for easier movement of individuals, including those with disabilities, during a crisis.

The legislation takes into account the need for swift exit routes while maintaining safety standards, thereby reducing potential hazards that may impede egress during an emergency situation. This requirement aligns with overall building safety protocols, affirming that all elements of a building's exit strategies contribute to effective evacuation processes.
