🔍 Key Concepts

• Confined spaces like chain lockers often have low oxygen and toxic or flammable gases • The difference between measuring oxygen level and supplying oxygen to breathe • The purpose of a combustible gas indicator vs an oxygen-measuring device

💭 Think About

• Which device is specifically designed to tell you the percentage of oxygen present in the air of a space? • Which choice is equipment you would wear or use to survive in a bad atmosphere, rather than to measure it? • Does a combustible gas indicator directly measure oxygen content, or is it focused on something else?

✅ Before You Answer

• Identify which option is a testing/instrument device intended to measure oxygen concentration in air • Eliminate any option that is primarily respiratory protection rather than a measuring tool • Confirm whether a combustible gas indicator is for flammable vapors or oxygen level detection
