FirefightersExterior fire attack: Stacked materials, such as hay or straw bales, pallets or lumber (day)
Stacked materials, such as hay or straw bales, pallets or lumber. It happens during the day. With attack lines, hand tools, master stream devices and an assignment, you put out an outdoor fire in ordinary combustibles (Class A) from the outside: exposures are protected, the spread is stopped, collapse hazards are avoided, the water works, the fire goes out and the signs of where it started, or of arson, are preserved. It is station 4-9 of Ohio's Firefighter I practical exam (NFPA 1001 4.3.8), a live fire evolution run as a crew.
