Why are gaseous fuels considered particularly hazardous?

Gaseous fuels are considered particularly hazardous because they exist in a state that is already conducive to ignition. Unlike solid or liquid fuels, gaseous fuels can easily mix with air and form combustible mixtures, which can ignite with minimal energy input, such as a spark or flame. This characteristic makes them more dangerous in environments where they may accumulate, as they can ignite quickly and cause explosions or fires if not properly managed.

In industries where gaseous fuels are used, safety measures must be particularly stringent to prevent leaks and ensure immediate identification of any issues. The other options provided do not accurately reflect the inherent risks associated with gaseous fuels, particularly regarding their immediate readiness for ignition and the subsequent fire hazards they pose.
