70% to pass

A type B-III CO2 extinguisher has a rated capacity of _______________.

A 15 lbs
B 25 lbs
C 35 lbs
D 45 lbs
AI Explanation

The correct answer is C) 35 lbs. According to the US Coast Guard regulations, a Type B-III CO2 fire extinguisher must have a rated capacity of 35 lbs. This is specified in the Code of Federal Regulations (CFR) Title 46, Section 76.50-5, which outlines the requirements for fixed fire extinguishing equipment on vessels. The other options are incorrect because 15 lbs (A) is the capacity for a smaller Type B-I CO2 extinguisher, and 25 lbs (B) and 45 lbs (D) do not match the specific 35 lbs requirement for a Type B-III CO2 extinguisher.
