🔍 Key Concepts

• How an explosimeter is used in confined spaces on ships • Difference between identifying a gas and detecting its presence and concentration • What instrument is normally used to measure oxygen levels in an atmosphere

💭 Think About

• Ask yourself: Does an explosimeter tell you what gas is present, or only whether a flammable mixture is present at certain percentages of the Lower Explosive Limit (LEL)? • Consider which device would be used to check for safe oxygen levels before entering a confined space on board. • Think about whether a single portable instrument is normally designed to perform all three jobs listed, or if different instruments are used for different hazards.

✅ Before You Answer

• Verify whether an explosimeter measures gas composition or only flammable concentration vs. LEL. • Confirm what type of meter is normally used as an oxygen indicator in enclosed spaces. • Check if training materials describe explosimeters as "gas identifiers" or as flammable gas detectors.
