The study conducted a detailed evaluation of fire statistics from four countries to compare the number of deaths and injuries from structure fires started by a small open flame ignition source relative to death counts from fires started by smoking materials. The analysis indicated that smoking material ignition fires tend to more commonly result in fatalities relative to other low-energy ignition fires.1 Source: Anderson, Austin, and Marc Janssens. “A multi-national survey of low-energy and smoking materials ignition fires.” Fire technology 52, no. 6 (2016): 1709-1735.
