G2 Gas Fitter Practice Exam

The correct answer highlights organizations that are recognized for their role in the certification of gas appliances in Canada, specifically the Canadian Gas Association (CGA) and Underwriters' Laboratories of Canada (ULC).

The Canadian Gas Association plays a crucial role in the promotion and advancement of natural gas usage and safety practices within Canada. It develops standards and provides guidelines that are essential for ensuring the safety and effectiveness of gas appliances.

Underwriters' Laboratories of Canada, on the other hand, is a well-respected (and international) organization dedicated to safety testing and certification. ULC evaluates gas appliances to ensure they meet safety requirements and performance standards. Their certification is recognized across the industry, making them essential contributors to appliance safety and reliability.

The other answer choices reference organizations that either do not focus on gas appliances or are not dedicated to their certification in Canada. This emphasizes the importance of understanding the specific roles and functions of these accredited bodies when it comes to the safe operation of gas appliances within the country.
