🔍 Key Concepts

• USCG portable fire extinguisher classifications (what B-II means in terms of CO₂ capacity) • Difference between empty (tare) weight and fully charged gross weight • How many pounds of CO₂ agent are required for a B-II extinguisher by regulation

💭 Think About

• First, recall or look up how many pounds of CO₂ are required for a B-II rated portable extinguisher. • Then, add that required CO₂ weight to the given empty weight (34 lbs) to get the fully charged weight. • Compare your calculated full weight to the answer choices and see which one matches your sum.

✅ Before You Answer

• Be sure you are using the correct CO₂ charge (in pounds) for a B-II extinguisher, not for B-I or another type. • Confirm you are adding the CO₂ charge to the empty weight, not subtracting or averaging. • Double-check that your final number exactly matches one of the multiple-choice options before you choose.
