Curt Isakson’s article discusses the critical decisions fireground commanders face when selecting fire hoses, highlighting that bigger isn’t always better. Isakson explains that while large-diameter hoses (LDH) can transport significant volumes of water, they are bulky and difficult to manage, requiring extensive manpower to maneuver. In contrast, smaller hoses like the 3-inch variety offer easier handling and faster deployment, often with fewer personnel.

Isakson also addresses the phenomenon of “hose creep,” where hoses expand under high pressure, potentially complicating flow rates and friction loss calculations crucial for effective water delivery. He advocates for a strategic approach in hose selection, emphasizing the importance of choosing the right hose based on tactical needs and quality to enhance fire suppression effectiveness.
