What component can contribute to the ignition of a gas fire?

Fugitive gases refer to the unintended release of gas, which can create a hazardous condition conducive to ignition. These gases are not contained and can accumulate in an area, especially in poorly ventilated spaces. When a sufficient concentration of fugitive gases is present and an ignition source, such as a spark or flame, is introduced, it can lead to a fire or explosion. This makes fugitive gases a significant factor in the ignition of gas fires, as they can increase the flammability of the environment.

On the other hand, fire blankets, circuit breakers, and non-combustible materials do not directly contribute to the ignition of a gas fire. Fire blankets are designed to smother flames and are a safety measure rather than a contributing factor to ignition. Circuit breakers are safety devices that prevent electrical overloads and are not related to gas fires. Non-combustible materials are resistant to fire and do not facilitate ignition but can be used in fire prevention strategies. Thus, fugitive gases are directly linked to the potential ignition of a gas fire.
