What is the minimum number of floors that necessitates the installation of wet standpipes for schools, hospitals, businesses, and similar structures according to RA 9514?

The correct answer is based on the provisions outlined in the Republic Act 9514, also known as the Fire Code of the Philippines. According to this legislation, structures such as schools, hospitals, and businesses that have a certain height requirement must be equipped with wet standpipes for fire protection.

Wet standpipes are necessary for buildings that exceed a designated number of floors because they provide a readily accessible water supply for firefighting operations. These systems are crucial in ensuring that firefighters can effectively combat fires in taller buildings where access to water might be more challenging as compared to single or low-rise structures.

In this context, the legislation specifies that if a building has four or more stories (or floors), it necessitates the installation of wet standpipes. This requirement enhances safety conditions in larger buildings, emphasizing the need for efficient and reliable fire suppression methods to protect both occupants and property.

Understanding this requirement is essential for compliance with fire safety standards, ensuring that fire safety measures meet the risks associated with taller structures.
