🔍 Key Concepts

• Gas testing procedures for cargo tanks before loading, especially with vapor recovery systems • How oxygen concentration can vary with height inside a tank • Why sampling points must represent both top and bottom tank conditions

💭 Think About

• Think about how gases and vapors stratify in a cargo tank: will the oxygen content be the same at the top and bottom? • Which answer gives you sampling points that are both representative of the whole tank and practical for routine testing? • Consider how ullage (empty space above the liquid) affects where you would want to measure oxygen before loading.

✅ Before You Answer

• Identify which options include both an upper and a lower sampling point in the tank. • Check which option uses ullage in a way that actually makes sense physically and operationally. • Verify which spacing of measurements would most likely be found in a standard operating procedure rather than an emergency or research situation.
