The preincident survey should identify the location of standpipes and which other feature to limit the spread of fire?

• A. Firewalls
• B. Fireload density
• C. Access roads
• D. Utility shutoffs

Answer: (A)

Fires spread mainly through connected spaces, so identifying built-in barriers that resist flame and heat is essential. In a preincident survey, locating standpipes helps firefighters access water, but showing where firewalls are located reveals how the building is compartmentalized to slow or stop fire spread. Firewalls are rated barriers designed to resist heat for a specified time, maintaining separation between sections and protecting critical areas like stairwells and escape routes. This containment helps limit how far the fire can travel. Access roads aid in reaching the building but don’t physically impede spread. Fireload density affects how intense the fire may become, not how it moves between areas. Utility shutoffs reduce hazards but don’t contain the fire itself. So, the feature to identify alongside standpipes to limit spread is firewalls.
