What is the minimum seat width per person required in assembly seating without arms as per RA 9514?

The minimum seat width per person required in assembly seating without arms, as specified by the RA 9514 (Fire Code of the Philippines), is 600 mm. This standard is important for ensuring that each individual has adequate space for comfort and safety during gatherings. The rationale behind this width is to accommodate a range of body sizes and to facilitate easy movement within the seating area. This is particularly crucial in emergency scenarios, where swift evacuation might be necessary.

The law emphasizes the need for such specifications to avoid overcrowding and to promote safety in public assembly areas. The dimensions set forth ensure that there’s enough room for each person to sit comfortably without encroaching on another's space, thereby enhancing the overall experience of the assembly. Each seat should thus provide not just for comfort, but also contribute to the orderly conduct of safe emergency exits, which is a fundamental concern in building safety regulations.
