What is a major cause of structure fires during winter?

Improper use of heating equipment is a major cause of structure fires during winter because many people rely on additional heating sources to stay warm in cold weather. This includes devices such as space heaters, fireplaces, and wood stoves. If these heating devices are not used according to safety guidelines—such as placing them too close to flammable materials, neglecting to supervise them while in use, or failing to maintain them properly—there is an increased risk of ignition.

During winter months, homes are often sealed tightly for insulation, which may also encourage the buildup of combustible materials around heating sources. This combination of reliance on supplementary heat sources and inadequate safety measures makes improper use of heating equipment a significant factor in winter structure fires.
