What is the minimum travel distance to an exit in a building with an approved sprinkler system according to PD 1096?

The correct answer is 60 meters, which is significant in the context of building safety and design standards provided by PD 1096, also known as the National Building Code of the Philippines. This code outlines various safety measures to ensure structural integrity and occupant safety, including regulations regarding egress routes.

In buildings equipped with an approved sprinkler system, the minimum travel distance to an exit is established as 60 meters. This distance is an important consideration because it takes into account the fire protection provided by the sprinklers, which can help control or suppress a fire, allowing for safer evacuation. Therefore, the increased travel distance compared to buildings without such systems reflects the additional safety measure provided by the sprinklers.

Remaining options, like 30 meters, 45 meters, and 75 meters, do not align with the code provisions established for buildings with sprinklers. The focus on 60 meters as a standardized travel distance ensures adherence to safety regulations that account for the potential hazards in a building's environment while enabling effective evacuation routes.
