What temperature range is typical for igniting household items?

The typical temperature range for igniting household items falls within 450 to 650 degrees Fahrenheit. This range reflects the average autoignition temperatures for various common materials found in households, such as wood, paper, and textiles. These materials undergo chemical changes at these temperatures, resulting in combustion when sufficient heat is applied.

While lower temperatures can ignite some materials, they usually require additional factors, such as prolonged exposure or the presence of an open flame. Higher temperature ranges are generally associated with materials that are less common in typical household environments or require specific conditions to ignite effectively. Thus, the selected temperature range is most relevant to the everyday scenarios encountered in residential fire investigations, where household items are the primary fuels involved in fire incidents.
