🔍 Key Concepts

• Fixed vs. portable extinguishers and how their contents are verified • Properties of Halon as a clean agent (stored as a liquefied gas under pressure) • Typical methods for determining the amount of agent in non-transparent, high-pressure cylinders

💭 Think About

• If you cannot see inside the cylinder, what reliable method would give you an accurate measurement of how much agent is left? • Which method would be least affected by gauge failure, damaged tags, or human error in record-keeping? • For a liquefied gas agent like Halon, what physical property changes in a predictable way as the contents are used?

✅ Before You Answer

• Verify which method is quantitative, not just a visual or record check • Consider which options could be inaccurate if a gauge sticks or paperwork is wrong • Think about standard marine practice for CO2 and Halon cylinders on fixed systems and large portable units
