Question 831 Deck Safety

The correct answer is A) Carbon dioxide. Carbon dioxide (CO2) fire extinguishers are the only type of portable fire extinguisher that is normally recharged in a shore facility. This is because CO2 extinguishers require specialized equipment and procedures to properly recharge the cylinder with high-pressure CO2 gas. The other types of extinguishers, such as water, dry chemical, and water-cartridge operated, can typically be recharged on board the vessel by the crew. The other answer choices are incorrect because water, dry chemical, and water-cartridge operated extinguishers do not require the specialized equipment and procedures necessary for recharging CO2 extinguishers, and can be recharged aboard the vessel.
