In the described material, which fire class is noted to be addressed with fog attack as the primary extinguishing approach?

• A. Class Charlie
• B. Class Bravo
• C. Class Alpha
• D. Class K

Answer: (A)

Fires involving electrical equipment require cooling without creating a conductive path for current. Using water in a fog pattern delivers rapid heat absorption and cooling with wide, gentle coverage, which blankets the flames while reducing the risk of arcing or spreading fire across energized components. The fine droplets cool the hot surfaces efficiently and the resulting steam helps displace heat, making it safer to approach the fire. If power can be shut off, that’s ideal, but when you must attack near energized gear, a water fog attack is the preferred method because it provides effective extinguishment while minimizing electrical risk. This is why the material identifies this fire class as the one addressed primarily by fog attack.
