Question 1009 Deck Safety

The correct answer is D) 14. The symbol 14 on the Fire Control Plan represents a CO2 fire extinguisher, which is the best means to extinguish a large Class B (flammable liquid) fire. CO2 extinguishers are effective on Class B fires because the carbon dioxide displaces oxygen, smothering the fire. They are well-suited for large Class B fires due to their high extinguishing capacity compared to other portable extinguishers. The other options, 44 (foam), 39 (dry chemical), and 36 (water), are not the optimal choices for a large Class B fire. Foam and water are less effective on flammable liquid fires, while dry chemical extinguishers may not have sufficient capacity to handle a large Class B fire.
