Reignition due to latent heat, sparks, or embers or due to presence of smoke or steam.
An instance where fire department is called back to a location because of re-ignition by latent heat, sparks, or embers or due to presence of smoke or steam. A rekindle is considered somewhat of a professional embarrassment due to inadequate opening up or overhauling. Re-ignition seven or eight hours after a severe fire is not unusual and is one reason why watch lines and details should be maintained for a considerable time after a major fire.
A return to flaming combustion after incomplete extinguishment, such as a fire re-igniting at some time after being put out. Residual heat and hidden embers may restart a fire several hours after it has been declared out if overhauling has not been sufficiently thorough.
The re-ignition of a fire because of latent heat, sparks, or smoldering embers; can be prevented by proper overhaul.
