Which tools can be used for small hidden fires?

• A. Water extinguishers
• B. Booster lines
• C. Both water extinguishers and booster lines
• D. Foam nozzle

Answer: (C)

Small hidden fires burn in concealed spaces, so the goal is to get water into those voids to cool and dampen embers and prevent rekindling. Water extinguishers are portable and can be used to dampen or saturate areas through small openings, making them effective for quickly addressing hidden pockets of flame or heat. Booster lines, with their greater reach and flow, allow you to reach into tight spaces or from a safer distance to apply sustained water coverage where a handheld extinguisher might not reach. Foam nozzles are designed primarily for spreading foam on surface fires involving hydrocarbons and require foam concentrate and mixing; they’re not the ideal tool for flushing out or cooling fires hidden in walls or ceilings, where direct water application and reach are more critical. So, both water extinguishers and booster lines are suitable for small hidden fires, which is why the best answer combines them.
