Which code is most commonly used to regulate life safety in buildings in the United States and is referenced in Texas building practice?

• A. NFPA 70
• B. International Building Code
• C. NFPA 101 Life Safety Code
• D. NFPA 13

Answer: (C)

The main idea here is life safety design and regulation in buildings. The document that focuses specifically on protecting occupants—through means of egress, fire protection features, alarms, and overall safety strategies—is NFPA 101 Life Safety Code. It’s widely used across the United States and is commonly referenced in Texas building practice to ensure that safety protections are in place regardless of the building type.

Other codes shown here play different roles. NFPA 70 governs electrical safety, which is important but not the broad life safety framework. The International Building Code provides the overall building requirements and is often adopted as the base code, with NFPA 101 referenced for detailed life safety provisions. NFPA 13 deals with sprinkler system design and installation, which supports fire protection but is not the comprehensive life safety standard by itself.
