What information must be included on the label at the fueling connection receptacle?

The label at the fueling connection receptacle must include identification as a CNG vehicle and the service pressure because this information is essential for safety and operational efficiency. Identifying the vehicle as a CNG vehicle ensures that personnel are aware of the type of fuel being used, which is crucial for handling and for any emergency situations that may arise. The service pressure is necessary to ensure that the fueling system operates within safe limits, preventing potential leaks or failures during the fueling process.

This information helps in maintaining safety standards and prevents accidents that can occur if the equipment is mismatched or if personnel are unsure of which type of fuel they are dealing with. Hence, the inclusion of both the vehicle identification and the service pressure on the label is mandated for regulatory compliance and safety protocols in handling compressed natural gas.
