(549) - ANSWER Woven-jacket natural fiber What should be done to prevent damage when drying fire hose in hose towers or on racks? (549) - ANSWER Secure the couplings to the rack or tower Hose that is stored in the fire apparatus bay: (550) - ANSWER Must be inspected and cleaned more frequently due to exposure to oil, gasoline, and airborne contaminants To prevent damage to hose when storing it in racks, the hose should be: (551) - ANSWER Rolled with the male coupling inside the roll How can mechanical damage to hoselines be avoided? (552) - ANSWER Deploy hoselines away from debris What action should be taken to protect fire hose in extremely cold temperatures when it is only being used intermittently at a fire? (553) - ANSWER Allow some water to flow through the nozzle when it is not being used in order to keep it from freezing Which statement accurately describes organic damage to fire hose? (553-554) - ANSWER When natural fiber hose is stored wet, it is at risk of mold and mildew damage Exposure to ________ will react to rapidly separate the inner lining of the hose.
