What is the minimum clearance above and below a mezzanine according to PD 1096?

The minimum clearance above and below a mezzanine according to PD 1096 is correctly identified as 1.8 meters. This height requirement is essential to ensure safety and accessibility, providing ample space for users to move freely without the risk of head injuries or obstruction. Clearances are a critical aspect of building codes, as they govern the height of spaces to accommodate not just movement but also the installation of utilities if necessary.

PD 1096, which refers to the National Building Code of the Philippines, stipulates these dimensions based on considerations such as comfort, safety, and usability of the mezzanine space. Adhering to this regulation helps in creating a built environment that is both functional and compliant with established standards for safety in building design.
