The objective in NFPA 13R is to allow occupants to escape in case of fire for how many minutes?

• A. 20
• B. 30
• C. 60
• D. 15

Answer: (B)

NFPA 13R focuses on providing life safety in one- and two-family dwellings by giving occupants a real chance to get out after a fire starts. The protection is designed so that conditions remain tenable long enough for people to evacuate for about 30 minutes, giving a reasonable window for them to reach safety and for responders to arrive. That 30-minute figure reflects the typical residential fire growth and the need for a practical egress time in low-rise homes. The other times don’t align with this safety window for residential sprinkler protection.
