🔍 Key Concepts

• Enclosed space entry procedures and why oxygen levels must be measured, not assumed • Difference between ventilation (adding fresh air) and atmospheric testing (measuring what’s there) • Limitations of a combustible gas indicator compared to an oxygen indicator

💭 Think About

• Before entering a rarely used cargo tank, what TWO separate steps are normally required by enclosed space entry procedures? • Does simply opening a tank or looking at surfaces inside give you any measured information about oxygen percentage? Why or why not? • What is the specific instrument designed to measure oxygen concentration, and how does that differ from instruments designed for flammable gases only?

✅ Before You Answer

• Verify which option includes both active ventilation with fresh air AND direct measurement of oxygen level. • Check whether any choice relies only on visual clues or time with hatch open instead of an actual test instrument. • Confirm which instrument can only detect flammable gases and may not show low oxygen conditions, versus one that directly measures oxygen percentage.
