What is involved in the ignition sequence?

The ignition sequence refers to the specific series of events that lead to the initiation of a fire. This involves the combination of three key elements: fuel, an ignition source, and oxygen, which together create the conditions necessary for combustion to occur.

In the context of the ignition sequence, option C accurately describes the process where events line up to allow fuel to come into contact with an appropriate ignition source, which is crucial for starting a fire. This understanding is fundamental in fire prevention and safety practices, as controlling either the fuel or the ignition source can effectively prevent a fire from starting.

The other options do not fit the definition of an ignition sequence. Events preventing ignition or focusing on the results of fire suppression efforts or the aftermath of a fire incident do not encapsulate the proactive nature of the ignition sequence itself, which is centered on how combustion begins.
