What is the weight of the 45 min bottle?

Explanation:
The weight being tested is how heavy a fully filled 45-minute SCBA bottle is. In firefighting gear, the bottle’s weight is the mass after it’s filled with air, not just the empty cylinder. A 45-minute bottle designed for training and field use is typically around 13.9 pounds when full. This reflects a balance between having enough air for about 45 minutes and keeping the gear manageable to carry. Weights near 12.5 pounds would generally not provide a full 45 minutes of air, while weights like 14.2 or 15.0 pounds suggest a heavier cylinder or more air than the standard 45-minute bottle. So 13.9 pounds matches the expected full weight for this type of bottle in PPE drills.
