HVAC - EPA Certification Practice Exam

How often should recovery cylinders be hydrostatically tested?

1. Every 2 years

2. Every 5 years

3. Every 10 years

4. Only when damaged

The correct answer is: Every 5 years

Recovery cylinders should be hydrostatically tested every 5 years to ensure their integrity and safety for use in handling refrigerants. This periodic testing is crucial because it verifies that the cylinders can withstand the pressures they are subjected to during the recovery process without leaking or failing. Over time, materials can weaken due to factors like corrosion, fatigue, or environmental conditions, making it essential to confirm their reliability on this regular schedule. This practice protects both the user and the environment by minimizing the risk of refrigerant leaks or cylinder ruptures. In contrast, testing every 2 or 10 years does not align with the guidelines established by regulatory bodies, as such intervals may either be too frequent, increasing unnecessary costs, or too infrequent, posing safety risks. Testing only when damaged does not comply with safety protocols that emphasize proactive measures rather than reactive responses to potential issues. This underscores the importance of adhering to established regulations for the maintenance and safety of recovery equipment in HVAC practices.
