What is the force requirement for a breakaway device to separate during an incident?

The force requirement for a breakaway device to separate during an incident is an important safety consideration in the design of systems that handle compressed natural gas (CNG). A breakaway device is intended to allow a fuel line to disconnect safely to prevent spills, leaks, or other hazardous situations when a certain force is applied, such as during a collision or sudden movement.

Selecting a maximum separation force of not greater than 150 pounds establishes a balance between providing enough strength to keep the system intact during normal operation and ensuring that the device will release under excessive force that could indicate a dangerous condition. This specific threshold is chosen to minimize the risk of hazardous incidents while maintaining the integrity of the CNG delivery system under normal operating conditions.

The other choices imply higher force requirements, which could lead to situations where the equipment remains intact during an incident, potentially allowing for gas leaks or other dangers to occur. Thus, the selected force requirement aligns with safety regulations and best practices for CNG delivery operations.
