According to regulations, how must cylinders be manufactured for CNG service?

Randomly without inspection
In accordance with DOT regulations and exemptions
Only based on manufacturer standards
Using untested materials

The correct answer is: In accordance with DOT regulations and exemptions

Cylinders used for CNG service must be manufactured in accordance with Department of Transportation (DOT) regulations and any applicable exemptions. This ensures that the cylinders are designed, tested, and constructed to meet strict safety standards that are necessary for handling compressed natural gas. These guidelines establish material requirements, pressure testing, and quality control measures that are vital for the safe storage and transport of CNG. Compliance with DOT regulations helps to minimize risks associated with leaks and cylinder failures, ultimately protecting the safety of drivers and the public. While options focusing on random manufacturing, solely manufacturer standards, or using untested materials would compromise safety and reliability, they do not align with the rigorous standards established for CNG cylinder production. Therefore, adherence to DOT regulations is imperative for the safe operation of CNG vehicles.
