Which statement is true about low-pressure systems in relation to EPA 608 certifications?

• A. Type II covers low-pressure systems.
• B. Type II does not cover low-pressure systems; Type I and III cover those as part of universal certification.
• C. Type II is for low-pressure only.
• D. Low-pressure systems are not regulated.

Answer: (B)

Low-pressure work is not within the Type II scope. Type II certifies high-pressure appliances, while low-pressure appliances are covered by Type III; universal certification includes all three types (I, II, and III), so it also covers low-pressure work. So the statement is accurate: Type II does not cover low-pressure systems, and low-pressure work is handled by Type III (or by holding universal certification). This contrasts with the idea that Type II would cover low-pressure, or that low-pressure work isn’t regulated.
