For containers manufactured before November 1, 1994, what information must still be readable on corroded nameplates?

The correct choice highlights the critical information that must remain legible on corroded nameplates for containers manufactured before November 1, 1994. The manufacturer's name is essential for identifying the source of the container, which is vital for safety, maintenance, and regulatory compliance, especially in the context of compressed natural gas delivery. Additionally, the working pressure indicates the maximum pressure the container is designed to withstand, which is crucial for assessing its ability to safely transport CNG.

If there is any corrosion or degradation of the nameplate, maintaining the readability of this information ensures that operators and handlers can verify the specifications of the container, which is important for both safety and legal reasons. The ability to confirm the manufacturer and working pressure helps prevent potentially hazardous situations that could arise from using a container that is not suitable for high-pressure contents or has not been properly maintained.
