It is common for codes to require a ______hour Fire-Resistive rating for corridor walls in health-Care facilities

• A. 1
• B. 0.5
• C. 2
• D. 4

Answer: (A)

Corridor walls in health-care facilities are part of the exit paths and must resist fire long enough to keep evacuation routes usable during a fire. The typical requirement is a one-hour fire-resistance rating because this duration provides a practical balance: it helps contain the fire and smoke to protect occupants as they evacuate and gives responders time to work, without incurring excessive construction costs. A shorter rating, like 30 minutes, wouldn’t reliably protect the egress route in the busy, mobility-challenged environment of a hospital. A higher rating, such as two or four hours, is usually reserved for fire walls that separate different occupancies or buildings, not for standard corridor walls within a single health-care facility.
