A structure fire that results from human negligence may be classified as what type of fire?

A structure fire that results from human negligence is classified as an accidental fire. This classification is used to describe fires that occur without intent to cause harm and arise from a failure to take proper precautions or care. For instance, an accidental fire could result from left candles burning unattended, a barbecue grill that has been improperly maintained, or failure to extinguish a campfire completely. The important aspect here is that, while human actions contributed to the fire, there was no malicious intent involved.

In contrast, an incendiary fire involves deliberate actions to start a fire with the intention of causing damage or harm. Natural fires occur due to natural elements like lightning and do not involve human intervention or negligence. Electrical fires stem specifically from faults or malfunctions in electrical systems or wiring. Therefore, the most fitting classification for a fire resulting from human negligence is accidental, as it encompasses situations where careless actions lead to unintentional consequences.
