Which component is essential for controlling safety during the handling of CNG?

The ASME Code is essential for controlling safety during the handling of compressed natural gas (CNG) because it provides guidelines and standards for the design, construction, and maintenance of pressure vessels and piping systems. These codes are specifically crafted to ensure that systems containing gas, such as CNG, are safe for operation under pressure. Compliance with the ASME Code mitigates the risk of failures that could lead to accidents or leaks, making it a critical framework for safety in the industry.

While other options like piping regulations, standard operating procedures, and safety monitors all play significant roles in ensuring the safe handling of CNG, the ASME Code sets the foundational standards on which these practices are built. It is recognized and utilized across the industry, thereby helping to maintain uniform safety practices that are essential in preventing hazardous situations.
