What would be the immediate action required for gas systems installed before 2000 that do not comply with current code?

  1. Retain existing installations without change

  2. Upgrade the system to meet current standards

  3. Contact the AHJ for guidance

  4. Request a variance from the code

The correct answer is: Contact the AHJ for guidance

When gas systems installed before 2000 do not comply with current code, the first step is to contact the Authority Having Jurisdiction (AHJ) for guidance. The AHJ is responsible for interpreting and enforcing building codes and regulations, including those related to gas installations. By reaching out to the AHJ, gas fitters can gain insight into the specific requirements, potential remedies, and the best course of action for existing systems that may not meet modern safety and performance standards. This step ensures that any subsequent actions, whether it involves upgrading the system or seeking variances, are taken with a clear understanding of regulatory expectations and compliance requirements. Engaging with the AHJ is essential to ensure that any modifications or assessments adhere to the latest codes and maintain safety for the users of the gas system.
