Question 1 of 27070

To determine that a compartment contains sufficient oxygen to sustain life, you should use a/an __________.

🔍 Key Concepts

• Confined space entry requirements for safe atmosphere • Difference between devices that measure oxygen content vs flammable vapors • Why "all of the above" is only correct when all devices do the same essential job

💭 Think About

• Which instrument is specifically designed to tell you if there is enough oxygen to breathe safely, not just if something will explode? • What does an explosimeter actually measure, and what is its primary safety purpose on a vessel? • If one device measures oxygen and another measures something different, can "all of the above" still be correct for checking breathable atmosphere?

✅ Before You Answer

• Verify which instrument directly reads oxygen percentage in air • Confirm what parameter an explosimeter is designed to detect (think: lower explosive limit / flammable gases) • Ask yourself if a fresh air indicator is a standard instrument name or if it sounds more like a general description rather than a specific meter
