Which situation necessitates reporting an incident involving CNG during transfer?

Reporting an incident involving compressed natural gas (CNG) during transfer is crucial for ensuring safety and compliance with regulations. A single release of CNG during or after transfer represents a potential hazard, as it could indicate a failure in the transfer process that may pose risks to safety and the environment.

When CNG is released, it can lead to dangerous situations such as fire, explosion, or harm to personnel and nearby property. Therefore, any incident of leakage, regardless of its size, should be documented and reported promptly. This not only helps in addressing the immediate problem but also facilitates investigations that can lead to improvements in safety protocols, training, and equipment.

Other scenarios, such as transfers that meet safety standards or have no leakage detected, do not indicate an incident that requires reporting since they fall within the acceptable operational parameters. Complete transfers without issues also do not present any risk or incident that warrants attention. Thus, the focus on reporting is specifically required when there is a release or spill, highlighting the critical nature of monitoring CNG transfers for safety.
