Which cabin extinguisher is noted as being larger than the others?

• A. The extinguisher in the lavatory vanity.
• B. The extinguisher in the cockpit.
• C. The extinguisher in the main closet.
• D. The extinguisher in the cabin overhead panel.

Answer: (A)

This focuses on understanding how extinguisher size is matched to the risk and access needs in different cabin areas. The lavatory vanity houses a larger extinguisher because a bathroom is a confined space with materials that can burn quickly and spread flames in multiple directions. A bigger unit provides more extinguishing agent and a longer discharge time, which helps suppress a fire promptly in that enclosed area before it grows out of control, without needing to move the canister to reach the fire. In the cockpit, main closet, and cabin overhead panel, the extinguishers are smaller because these locations are more open, easier to access quickly, and typically involve fires that can be attacked effectively with a lighter unit. The smaller units optimize weight and space while still offering adequate protection for those areas. So, the lavatory vanity extinguisher is larger to address the higher fire-suppression needs of that enclosed space, while the other locations use smaller extinguishers appropriate for their access and risk profiles.
