What dictates the standard for the designed operation of regulators?

The National Fire Protection Association (NFPA) regulations set comprehensive safety standards for various aspects of fire safety, including the operation of gas regulators. These regulations ensure that equipment operates safely under specific conditions, addressing factors such as installation, operation, maintenance, and performance standards. By following NFPA regulations, operators can mitigate risks associated with gas pressure and flow, thereby enhancing safety in the use of compressed natural gas systems.

While state guidelines, manufacturer's recommendations, and local safety codes can also contribute to the standards followed in the industry, NFPA regulations provide a nationally recognized framework that addresses safety comprehensively and is often seen as a benchmark for ensuring safe operation. Therefore, adherence to NFPA regulations is critical for ensuring that regulators function correctly and safely in all operational scenarios.
