Investigate a Range Top Fire

with NFE

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!

Identifying the Area of Origin

Area of Least Fire Damage

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.

Area of Greatest Fire Damage 

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.

What Can the Evidence Tell You?

If investigators do determine that a fire originated on a range top, they’ll then examine various indicators to identify the heat source, first material ignited, and ignition sequence.

Burn patterns define the fire origin and spread.

Written Report

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.

Conducting Product Failure Testing and Research

During a range top fire investigation,

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.

NFE recommendations

for next steps may include transporting evidence for further testing. For chemical testing, NFE packages debris and residue in sealed, unlined metal paint cans.
