Question 85Safety & Environmental - 1st Asst/Chief

The correct answer is A) turn the extinguisher upside down. To activate a foam type portable fire extinguisher, you must turn the extinguisher upside down. This inverts the extinguisher and allows the foam agent to be expelled under its own pressure. The other options are incorrect because they do not accurately describe the proper activation method for a foam extinguisher. Pulling the pin and squeezing the grips (B) is the correct method for dry chemical extinguishers. Pumping the hand lever (C) is for water-type extinguishers, and striking the bottom against the deck (D) will not activate a foam extinguisher.
