Can you purchase nitrogen without a 608 certification?

• A. No
• B. Yes
• C. Only with supervision
• D. Only for professionals

Answer: (B)

The main idea is that EPA 608 certification is about handling refrigerants, not general gas purchases. Nitrogen is not a refrigerant, so the certification isn’t required to buy it. In HVAC work, nitrogen is often used for purging and pressure testing because it’s inert and helps prevent moisture or contamination. Because it isn’t regulated under Section 608, you can purchase nitrogen without having that certification. Just follow standard safety for compressed gas cylinders—secure them, use proper regulators, and handle them with care. The other options would imply restrictions that don’t apply to buying nitrogen.
