FirefightersIgnitable liquid fire: Rain-down application (night)
Rain-down application. It happens at night. As a member of a team, with an assignment, an attack line, protective gear, a foam proportioning device, a nozzle, foam concentrates and a water supply, you put out an ignitable liquid fire: you choose the right foam for the fuel and conditions, lay a properly proportioned foam blanket on the fuel and keep it there, put the fire out, prevent reignition, protect the team with the foam stream and face the hazard until you reach a safe haven. It is station 5-3 of Ohio's Firefighter II practical exam (NFPA 1001 5.3.1).
