Aux 2 Unit 11 Quiz 2

Correct Answer:
C) It can condense and freeze, leading to regulator malfunction in cold water

Explanation:
Excessive water vapor in compressed air can condense inside the regulator and freeze when diving in cold water, potentially causing blockages and equipment failure.

Correct Answer:
B) Increased blood acidity and possible hypercapnia

Explanation:
Inhaling air with excessive carbon dioxide can lead to hypercapnia, a condition where there is too much CO2 in the blood, causing increased blood acidity, headaches, confusion, and even loss of consciousness.

Correct Answer:
B) Using a compressor without an efficient air drying system

Explanation:
If the compressor lacks an effective air drying system, water vapor can remain in the compressed air, which may later condense and cause issues such as corrosion or freezing in diving equipment.

Correct Answer:
B) Loss of consciousness or carbon monoxide poisoning

Explanation:
Carbon monoxide is a toxic gas that binds with hemoglobin in the blood, reducing its oxygen-carrying capacity. This can lead to carbon monoxide poisoning, which can cause symptoms such as dizziness, confusion, and even loss of consciousness.

Correct Answer:
B) Oil vapor

Explanation:
Oil vapor in the breathing air can cause respiratory irritation and potentially lead to long-term damage to the lungs if inhaled consistently or in large amounts.

Correct Answer:
B) Water vapor, carbon monoxide, and oil vapor

Explanation:
These contaminants pose health risks: water vapor can cause freezing and corrosion, carbon monoxide can lead to poisoning, and oil vapor can cause respiratory issues.

Correct Answer:
C) Improper maintenance or malfunction of the air compressor

Explanation:
Air compressors that are not properly maintained or are malfunctioning can release oil vapors or droplets into the compressed air, contaminating the air supply.
