Which of the following is an example of an accidental cause of fire?

An example of an accidental cause of fire is faulty wiring. This situation can lead to electrical failures or short circuits, which can ignite surrounding materials and ultimately start a fire. Faulty wiring does not involve malice or intentional negligence; rather, it stems from issues related to the design, installation, or maintenance of electrical systems. These types of accidents often occur due to wear and tear over time, improper installation, or failure to adhere to safety standards, reflecting the unintentional nature of the hazard.

In contrast, negligence in handling flammable materials typically involves a lack of care or caution that could be seen as intentional disregard for safety guidelines. Reckless use of fire indicates a deliberate choice to use fire in a dangerous manner, which is also intentional. Natural causes like lightning occur without human interaction or intent, but they do not fit the typical classification of accidental causes that stem from human error or oversight in infrastructure or equipment.
