The yellow flaked hoses on hangers are 110mm LDH which are used to set in to high volume hydrants, typically facilitating flows of 2000 or more LPM. The SOP is for the firefighters who are securing the water supply to shoulder these bundles and lay them out on their way from the pumper to the hydrant. Regular 70 mm hoses on the characteristic one man hose carts (already detached in this photo) are used for standard hydrant connections.
