Question 1106 Deck General

The correct answer is A) 55 pounds. According to the regulations for tank vessels, fire extinguishers that have a gross weight of more than 55 pounds are considered semi-portable, meaning they are not required to be hand-portable. Extinguishers with a gross weight of 55 pounds or less are considered fully portable. The 55-pound threshold helps differentiate between fire extinguishers that can be easily carried and those that may require mechanical assistance to move. The other options are incorrect because 75 pounds, 95 pounds, and 125 pounds all exceed the 55-pound limit for fully portable fire extinguishers on tank vessels.
