What is used to test a tank for oxygen content?

🔍 Key Concepts

• Enclosed space / tank entry procedures and what must be checked before entry • Difference between testing for oxygen content vs testing for flammable vapors • Instruments that measure O₂ percentage in air compared with those that measure explosive limits (LEL)

💭 Think About

• Ask yourself: which device or kit is specifically designed to tell you whether there is enough oxygen in the air for safe breathing? • Consider which instrument is normally used to detect the presence and concentration of flammable or combustible gases, rather than oxygen level. • Think about standard pre-entry gas checks: what three things are usually checked (oxygen, flammables, toxics), and which part of the equipment covers oxygen specifically?

✅ Before You Answer

• Verify which option names equipment that measures oxygen percentage by volume in air. • Check which options are normally associated with flammable / combustible gas concentration, often expressed as % of the Lower Explosive Limit (LEL). • Confirm that proper tank-entry testing typically uses a multi-gas or atmosphere testing kit and identify which answer choice best matches that description.
