Disclaimer:

Gas installation practices, fuel safety codes, and regulatory requirements evolve over time and may vary by jurisdiction. While the questions and explanations in this app are carefully prepared to reflect widely accepted gas technician knowledge and CSA B149 Natural Gas and Propane Code principles relevant to the TSSA G2 exam, differences in interpretation may occur.

If a user believes an answer may be incorrect or open to interpretation, the explanation reflects the most widely supported approach for exam preparation purposes. Users are encouraged to consult the latest editions of CSA B149, official trade training materials, and guidance from licensed gas technicians or instructors to confirm their understanding.

This app is intended as a supplemental study resource and does not replace formal apprenticeship training, field experience, or official TSSA exam preparation materials.
