What does LDH stand for?

Explanation:
Large Diameter Hose. In firefighting terminology, LDH refers to supply hoses that are larger in diameter than attack lines, typically 3 inches and up, used to move water from hydrants or other sources to the pump and then out to the attack lines. The bigger diameter reduces friction losses and supports higher flow over longer distances, which is why this type of hose is essential for water supply operations on the fire ground. The other phrases aren’t standard terms for this equipment, so they’re not used to describe the water-supply hose.
