Why should a smoldering ignition source not be disregarded?

A smoldering ignition source is particularly significant in fire investigations because it has the potential to transition into an open flame under the right conditions, leading to rapid fire spread. This transition can occur when the smoldering material encounters sufficient oxygen or additional combustible materials, which can dramatically increase the intensity and rate of the fire.

Understanding this characteristic allows fire investigators to recognize the danger posed by seemingly innocuous smoldering materials. The rapid escalation from smoldering to full combustion highlights the critical need for thorough examination and monitoring of all potential ignition sources during fire scene investigations. Identifying and addressing these risks can help prevent the potential for greater loss or damage.
