Which assignment is commonly performed by the second arriving company at a structure fire?

• A. Ventilation
• B. Interior attack
• C. Forcible entry
• D. Establishing water supply

Answer: (D)

Establishing water supply is crucial because an effective interior attack depends on a reliable source of water. The second arriving engine is typically positioned to secure a hydrant and lay a supply line to feed the first arriving engine’s pump and attack line. This keeps water flowing so crews can advance and apply water promptly without being delayed by finding or pressurizing a line. While ventilation, forcible entry, and interior attack are important tasks, they rely on having a steady water supply first, and the second engine is the unit best suited to set that up quickly and efficiently.
