What does "fire-rated construction" mean in NFPA 99?

The term "fire-rated construction" in NFPA 99 refers to building materials that must resist fire for a specified duration. This means that certain materials used in the construction of healthcare facilities must be capable of withstanding fire exposure for a set period, thereby providing a barrier that helps prevent the spread of flames and smoke. This is crucial in a healthcare context, where the safety of patients and staff is paramount, as well as the need to protect critical infrastructure and medical equipment.

By specifying that materials must have a fire-resistance rating, NFPA 99 aims to enhance safety and minimize fire hazards in facilities, ensuring adequate time for evacuation and containment efforts should a fire occur. This standard helps establish the necessary precautions that must be taken during the design and construction phases of healthcare facilities to ultimately protect lives and property.
