The bottle's weight in pounds is what?

• A. 13 lbs
• B. 14 lbs
• C. 15 lbs
• D. 17 lbs

Answer: (B)

The weight being asked is the weight of the cylinder itself, typically considered full for these kinds of SCBA problems. In many training problems, a standard 30-minute air cylinder filled to 4500 psi is specified as weighing about 14 pounds. This value is used because it reflects the common full-cylinder weight you’d carry on the unit, separate from the harness or mask. So 14 pounds is the best answer because it matches the standard full-cylinder specification used in typical SCBA practice problems. The other options would correspond to a different cylinder size/material or a different fill state (empty or partially filled), which isn’t the assumption in this question.
