Which extinguisher is primarily used outdoors for brush and grass fires?

• A. Water sprinkler extinguisher
• B. Backpack fire extinguisher
• C. ABC dry chemical extinguisher
• D. CO2 extinguisher

Answer: (B)

The key idea is mobility and reach in open, uneven terrain. For outdoors work on brush and grass fires, you want a unit you can carry on your back, move with through rough ground, and spray directly into low vegetation to cool the flames at the base. A backpack fire extinguisher fits this need perfectly: it’s designed to be worn like a pack, giving you quick, continuous access to water and a broad spray that you can sweep across the fireline as you move through the brush. This makes it especially effective for quickly knocking down light fuels and preventing spread in outdoor settings. Water sprinkler extinguishers are typically intended for fixed or indoor protection and aren’t as practical to shoulder-hop through grass and brush. CO2 extinguishers work well for small electrical fires in enclosed spaces but lose effectiveness outdoors and don’t provide the sustained reach needed for open-ground fires. ABC dry chemical extinguishers are versatile and useful for various fire types, but their powder can be blown away by wind and is harder to apply over large outdoor areas, making them less ideal than a backpack unit for brush and grass fires.
