Question 853 Deck Safety

The correct answer is B) greater range. Dry chemical fire extinguishers generally have a greater effective range than carbon dioxide (CO2) extinguishers. This is because the dry chemical agent is propelled from the extinguisher using a compressed gas, typically nitrogen or compressed air, which allows the agent to be projected a longer distance compared to the stream of CO2 gas from a CO2 extinguisher. The other answer choices are incorrect because: A) Cooling ability is not an advantage of dry chemical over CO2 extinguishers. Both types work primarily through smothering the fire, not cooling. C) Cleanliness is not necessarily an advantage, as dry chemical agents can be more difficult to clean up compared to the gaseous CO2. D) Not all of the above are advantages, as only the greater range is an advantage of dry chemical over CO2 extinguishers.
