Cooking was the leading cause of home fires and home fire-related injuries from 2017 to 2021, according to the latest data from the National Fire Protection Association (NFPA). Ranges and cooktops were involved in 53% of these incidents. These fires are often more complex than they seem, requiring detailed investigations to uncover the most plausible origin and cause. Come along on scene with National Fire Experts (NFE) for a look at what goes into these investigations!
When a policyholder reports that a fire started with a kitchen stove or cooktop, it’s essential to avoid confirmation bias—the tendency to interpret and favor information that aligns with one hypothesis and ignore or dismiss information that suggests other possibilities.
Instead of making any assumptions, NFE investigators follow NFPA 921 guidelines and use a systematic approach to uncover the fire’s most plausible origin. They start by interviewing the insured to gather background information. Then they conduct a thorough inspection of the home’s exterior, carefully examining the entire perimeter before moving inside. By analyzing fire patterns and progressing from the least damaged areas to those with the most severe fire damage, investigators determine where the fire began.

If clients do opt for a written fire report, these may include investigators’ observations and conclusions regarding the most plausible origin and cause of the fire, as well as recommendations for any additional testing or other next steps. Information contained within a report will depend on the type requested.

NFE investigators record the range’s brand, model, and serial number, unless they’re obscured due to severe fire damage. In this case, engineers can utilize non-destructive testing to assist in identifying the appliance brand and model.




Under Alpine Intel, NFE can also work closely with Component Testing Laboratories (CTL). CTL’s in-house transportation service, Loss Logistics, ensures a single-line chain of custody for evidence, while their Professional Engineers provide reliable, top-of-class reports based on the scientific method and engineering principles to deliver insights you can depend on to make subrogation decisions.
