🔍 Key Concepts

• Confined space hazards in areas like chain lockers • Difference between measuring oxygen concentration and detecting specific gases like H₂S or flammable vapors • Typical instruments used during a confined space entry permit check

💭 Think About

• First, ask yourself: which device is designed to directly read the percentage of oxygen in the air, rather than just detecting whether a gas is present or not? • Consider what each device in the options is primarily used for: which one is for flammable gases, which for toxic gases, and which for oxygen levels? • Think about standard pre-entry testing on ships: what instrument is used to confirm air is safe to breathe in enclosed spaces?

✅ Before You Answer

• Match each option to its primary purpose (flammable gas detection, toxic gas detection, oxygen concentration, or older-style mine safety). • Verify which device typically shows a numerical oxygen % reading, not just an alarm or yes/no indication. • Recall that safe entry usually requires around 20.9% oxygen – which instrument would you use to check that value?
