Aux 2 Unit 11 Quiz 4

Correct Answer:
B) Annually

Explanation:
It is generally recommended that SCUBA cylinders undergo a visual inspection at least once a year to check for corrosion, cracks, or other issues that may compromise safety.

Correct Answer:
B) The ability of the cylinder to withstand pressure without permanent deformation

Explanation:
A hydrostatic test involves pressurizing the cylinder to check for structural integrity and ensure that it can safely hold pressure without deforming.

Correct Answer:
B) It should be rinsed with fresh water to prevent salt buildup and corrosion

Explanation:
Rinsing a cylinder with fresh water after exposure to saltwater helps prevent corrosion and buildup of salt that could damage the cylinder.

Correct Answer:
B) Signs of external and internal corrosion, dents, and cracks

Explanation:
A visual inspection focuses on detecting any signs of corrosion, dents, or cracks that may compromise the cylinder’s integrity and safety.

Correct Answer:
B) To ensure proper air flow and prevent leaks

Explanation:
The valve should be inspected to ensure it functions correctly, allowing for proper air flow and preventing potential leaks that could endanger the diver.

Correct Answer:
B) To verify that the cylinder can safely withstand operating pressure

Explanation:
Hydrostatic testing ensures that the cylinder is capable of withstanding the pressure it will be subjected to during use without deforming or failing.

Correct Answer:
B) Using a light and inspection mirror to check for internal corrosion

Explanation:
Inspecting the inside of the cylinder with a light and mirror helps identify internal corrosion or damage that may not be visible from the outside.

Correct Answer:
C) Partially filled and stored upright in a cool, dry place

Explanation:
Storing cylinders partially filled and upright in a cool, dry place prevents internal moisture accumulation and minimizes the risk of corrosion.
