G2 Gas Fitter Practice Exam 2026 - Free Gas Fitter Practice Questions and Study Guide

The term for the time allowed for a flame safeguard control to de-energize the gas shut-off valves in the event of a loss of flame is known as flame failure response time. This concept is crucial for ensuring safety in gas-burning appliances. The flame failure response time is the duration within which the safety control system must react to detect that the flame has gone out and promptly signal the gas shut-off valves to close. This response is critical to prevent the accumulation of unburned gas, which can lead to dangerous conditions such as explosions or gas leaks.

Other options, while related to flame safety, do not accurately define this specific time parameter. Ignition safeguard time typically refers to the duration allowed for the system to confirm a successful ignition event, rather than the time taken to react to a loss of flame. Loss of flame delay might indicate a period for which the system tolerates a flame absence before responding, but it doesn't encapsulate the technical and regulatory standards associated with flame safety systems. Gas cutoff time, while it sounds relevant, is not a recognized term related to the specific functionality of flame safeguard systems. Thus, the most precise and accurate terminology for the situation described is indeed flame failure response time.
