What is used to test a tank for oxygen content?

A Atmosphere analyzer kit
B Vapor indicator
C Combustible gas indicator
D None of the above
AI Explanation

The correct answer is D) None of the above. The U.S. Coast Guard Captain's License Examinations do not test knowledge of using specific equipment to test the oxygen content of a tank. Checking the oxygen level in a tank is typically done using an oxygen analyzer, not an atmosphere analyzer kit, vapor indicator, or combustible gas indicator. These other devices are used to test for different properties, such as the presence of flammable vapors or the overall composition of the atmosphere, rather than specifically checking the oxygen level.
