Which standard must fire walls be designed and constructed in compliance with?

Fire walls must be designed and constructed in compliance with NFPA 221. This standard specifically outlines the criteria for fire walls, including their fire-resistance rating, design requirements, and the necessary conditions for their installation. NFPA 221 is crucial for maintaining safety in commercial buildings, as it provides guidance on how to limit the spread of fire and smoke between different sections of a building.

Understanding the specific requirements of NFPA 221 helps inspectors ensure that fire walls are not only compliant with safety regulations but also effectively mitigate potential hazards in the event of a fire. This standard plays a significant role in the overall fire protection strategy of a building, enhancing occupant safety and minimizing property damage.
