What is the minimum clear width of doors along an exit route for single/two-family dwellings according to RA 9514?

The minimum clear width of doors along an exit route for single and two-family dwellings, as stipulated by RA 9514 (the Fire Code of the Philippines), is set to ensure safe and efficient egress in case of an emergency. A clear width of 700 mm (or approximately 27.56 inches) is specified to facilitate the safe movement of individuals exiting the building. This width accommodates not only the passage of adults but also allows for the potential movement of individuals with mobility aids or carrying objects.

In contrast, other options propose widths that do not meet the established requirements for safety and accessibility. A 600 mm width may be too restrictive for optimal evacuation, while widths of 800 mm and 900 mm exceed the minimum specified by the code, resulting in unnecessary construction costs and regulatory burdens for residential buildings. Hence, the chosen dimension maintains a balance between safety regulations and practicality for single and two-family dwellings.
