🔍 Key Concepts

• All-purpose nozzle patterns (straight stream vs. fog) • Primary objectives when fighting Class A fires (ordinary combustibles like wood, paper, cloth) • How stream pattern affects reach, penetration, and cooling

💭 Think About

• For a Class A fire, when would you need maximum reach and penetration instead of wide area coverage? • Which pattern would you use if the burning material is deep-seated or difficult to reach directly? • Which choices describe benefits more commonly associated with fog patterns rather than a straight stream?

✅ Before You Answer

• Identify which option best matches long-range, concentrated application of water • Eliminate any options that describe tasks usually done with a fog or wide-angle pattern (e.g., heat shielding, atmosphere control) • Confirm that the remaining option is focused on delivering water into the seat of the fire, not on protecting crews or moving smoke
