G2 Gas Fitter Practice Exam

What is the function of a quick-disconnect device?

1. To manually adjust gas pressure

2. To connect and disconnect an appliance to the gas supply

3. To control the flow of gas in the piping system

4. To enhance safety by automatically shutting off gas

The correct answer is: To connect and disconnect an appliance to the gas supply

The function of a quick-disconnect device is to connect and disconnect an appliance to the gas supply easily and safely. This device is designed to allow for the rapid attachment or removal of appliances without the need for tools, making it particularly useful in situations where appliances need to be moved or replaced frequently. It enhances convenience for both installation and maintenance by enabling a secure connection that can be quickly disengaged when necessary. While manual adjustment of gas pressure, control of gas flow in the piping system, and enhancing safety by shutting off gas are all important aspects of gas fitting and appliance operation, they do not fall under the specific function of a quick-disconnect device. Such devices focus mainly on facilitating the connection and disconnection of gas appliances to ensure that these tasks can be performed quickly while minimizing risks of gas leaks or accidents during the process.
