Spontaneous combustion or spontaneous ignition, as it is often called, is the occurrence of fire without the application of an external heat source. Due to chemical, biological, or physical processes, combustible materials self-heat to a temperature high enough for ignition to occur. According to the National Fire Protection Association (NFPA), an estimated 14,070 fires occur annually from spontaneous combustion. Today we were lucky that it was only a deck that burned and the resident was able to put it out. The resident had recently stained the deck when todays bright intense sun ignited the deck at 10:15 AM
Use extreme caution on these hot sunny days with high winds, fire conditions are extreme right now.
