Answer 1

Per Title 49 CFR Section 173.34(e), cylinders and tanks must be hydrostatically retested at least once every 5 years to ensure their safety and integrity.

Step-by-step explanation:

According to Title 49 of the Code of Federal Regulations (CFR) Section 173.34(e), cylinders and tanks that are subject to these regulations must be hydrostatically retested a minimum of once every 5 years. The hydrostatic test is crucial for ensuring the safety and integrity of the vessel over time by verifying that it can safely hold pressure without leaking or showing signs of critical wear or damage. The frequency of the tests may change based on the specification of the cylinder or tank, the gas it contains, or any prior service conditions.
