Which incident necessitates reporting to AFS regardless of location?

Reporting a substantial release of CNG is critical due to the potential hazards it poses to safety and the environment. This type of incident can lead to serious consequences, including fires or explosions, and requires immediate attention from authorities to mitigate risks. Reporting such an event to the appropriate regulatory body, like the AFS (Air Force Safety), ensures that necessary precautions are taken and that proper procedures are followed for an effective response. The significance of a substantial release lies in its capacity to cause wide-reaching impacts, hence the need for strict reporting requirements regardless of the incident's location. This underscores the priority placed on safety measures in handling compressed natural gas operations.
