Fires occur when a competent ignition source and a fuel come together, provided what condition is met?

• A. Oxygen Content Is High
• B. They Stay in Contact Long Enough to Ignite
• C. Fuel Is Mixed With Water
• D. Ignition Source Is Below the Fuel

Answer: (B)

Ignition requires heat to be transferred from the ignition source to the fuel for a sufficient time so the fuel reaches and maintains its ignition temperature. Even with a competent source and the presence of oxygen, without staying in contact long enough, heat is lost to the surroundings and the fuel won’t ignite. So the essential condition is that the contact lasts long enough for enough heat transfer to occur to ignite the fuel.
