When must fuel oil systems be upgraded or reviewed for compliance?

Fuel oil systems must be upgraded or reviewed for compliance, particularly when significant changes are made to the system or if recurring issues are observed. This approach ensures that any modifications or persistent problems are addressed proactively, maintaining safety and compliance with relevant regulations.

Monitoring for recurring issues helps identify potential risks that may arise from existing deficiencies or outdated practices. Significant changes might include alterations in the system design, increased fuel capacity, or modifications in the usage of the fuel oil, all necessitating a thorough review to ensure that current standards and safety protocols are met.

In contrast, the alternative options do not recognize the ongoing nature of system maintenance and compliance. Compliance should not solely depend on new laws, occur at fixed intervals without regard to actual system conditions, or only be prompted by an incident such as a leak, as these approaches may lead to dangerous oversights or non-compliance.
