When approaching a fire from windward, you should shield firefighters from the fire by using an applicator and __________.
• heat shielding techniques when advancing on a fire • difference between low-velocity fog and high-velocity fog patterns • how water droplets absorb heat and protect firefighters
• Think about which type of spray pattern creates a wide screen of water droplets that can block radiant heat best. • Consider which option would deflect heat and smoke away from the firefighters instead of pushing heat, steam, or burning material toward them. • Ask yourself which stream pattern is most commonly used for personnel protection when advancing hose lines toward a fire.
• Verify which pattern forms a protective curtain or screen of water between firefighters and the fire. • Check which option is recommended for approach and protection, not just extinguishment. • Confirm which pattern minimizes steam burns and heat reflection back onto the firefighters.
