What is a common cause of residential fires?

The correct answer highlights that improper use of candles is a common cause of residential fires. Candles can easily ignite nearby flammable materials such as curtains, furniture, or paper if they are left unattended, placed too close to other objects, or not secured properly. This risk is exacerbated during situations where individuals may fall asleep or become distracted, leading to a fire that can quickly spread through the home.

While using smoke detectors, maintaining appliances, and participating in fire safety education programs are all essential components of fire prevention and safety, they do not directly contribute to the occurrence of residential fires. Instead, smoke detectors serve to alert occupants to a fire, regular maintenance helps prevent appliance-related hazards, and education programs aim to enhance overall awareness and safety practices. Recognizing the specific risks associated with items like candles can help individuals take proactive measures to mitigate fire hazards in their homes.
