Question 52Safety & Environmental - 1st Asst/Chief

The correct answer is D) of all of the above. The explanation is as follows: 1) Water applied as a fog can be more effective than water applied as a solid stream because: A) It reduces the total amount of water that must be pumped into the ship to fight a given fire, as the fog has better coverage and heat absorption. B) A given amount of water can absorb more heat when it is in the form of a fog, due to the increased surface area and vaporization. C) The fog does not have to directly hit the seat of the fire to be effective, as the fine water mist can absorb heat and displace oxygen over a wider area. 2) All of these factors make water applied as a fog more effective than a solid stream for firefighting on ships and other confined spaces, as per Coast Guard regulations and best practices.
