Which addendum specifically relates to the communications and venting aspect of Pressure Relief Devices?

• A. ANSI/IAS PRD 1a
• B. ANSI/CSA PRD 1b
• C. ANSI/IAS PRD 1
• D. 49 CFR 571.304

Answer: (B)

The correct choice pertaining to the communications and venting aspect of Pressure Relief Devices (PRDs) is ANSI/CSA PRD 1b. This particular addendum is focused on the standards and requirements necessary for the proper design, installation, and maintenance of PRDs with a specific emphasis on aspects including communications protocols and venting characteristics. These elements are crucial for ensuring that PRDs operate effectively to prevent overpressure situations, thus enhancing safety in the handling and transport of compressed natural gas. In contrast, ANSI/IAS PRD 1 and its related variations address broader safety standards and operations related to PRDs but may not specifically delve into the particular communications and venting protocols as the “b” addendum does. Similarly, 49 CFR 571.304 pertains to federal regulations for motor vehicle safety standards, which while relevant to the transport context, is not specifically dedicated to PRDs and their communication and venting requirements.
