Question 736Deck Safety70% to pass
Deficient oxygen content inside a chain locker can be detected with _______________.
AI Explanation
The correct answer is B) an oxygen indicator.
Deficient oxygen content inside a chain locker can be detected using an oxygen indicator, which is a device specifically designed to measure the level of oxygen in an enclosed space. Chain lockers are prone to having reduced oxygen levels due to rust, corrosion, and the storage of heavy anchor chains, so an oxygen indicator is the appropriate tool to safely assess the atmospheric conditions before entry.
The other answer choices are not suitable for this purpose. Litmus paper (A) is used to test acidity, not oxygen levels. A combustible gas indicator (C) detects the presence of flammable gases, but not specifically oxygen deficiency. An oxygen breathing apparatus (D) is used for respiratory protection, not for detecting oxygen levels.
