AI Explanation
The correct answer is D) All of the above. This is the correct answer because all three methods are the most effective way to fight a fire on the open deck of a vessel using a dry chemical type fire extinguisher. Approaching the fire from the windward side ensures the extinguisher discharge is directed at the base of the fire, which is the key to effectively extinguishing the flames. Additionally, using a rapid sweeping motion helps to cover the entire area of the fire and prevent it from reigniting. Following these best practices as outlined in Coast Guard regulations is the most effective way to safely and efficiently extinguish an open deck fire using a dry chemical extinguisher.
