Which term describes spaces with low fire risk and hazards?

• A. Light Hazard Occupancies
• B. Nonmetallic Pipe
• C. Gauge Pressure
• D. ASME B16.4

Answer: (A)

Spaces with very low fire risk and hazards are described as light hazard occupancies. This labeling helps sprinkler designers tailor the system to areas like typical rooms in homes—living rooms, bedrooms, and similar spaces—where the fire load is limited and ignition factors are modest. Classifying as light hazard guides lower design densities and simpler sprinkler layouts appropriate for residential, low-rise systems under NFPA 13R. The other terms don’t describe fire risk levels or space classifications. Nonmetallic pipe is a material, gauge pressure is a measurement, and ASME B16.4 is a piping fittings standard.
