What are common indicators of a potential fire hazard?

Being alert to potential fire hazards is crucial for safety. The indicators listed in the correct choice clearly represent conditions that could lead to a fire occurring. Overloaded power outlets can overheat and cause electrical fires, and faulty wiring may result in short circuits or electrical failure. Additionally, blocked exits pose a significant risk because they can prevent safe evacuation during an emergency situation, potentially trapping individuals inside a building where a fire might break out. Together, these factors highlight critical safety concerns that need to be addressed to prevent a fire.

On the other hand, open windows and doors, while potentially indicating poor conditions for fire control, are not direct indicators of a hazard. Adequate ventilation is actually beneficial as it helps control smoke and heat during a fire, and surrounding greenery may be helpful in providing a buffer zone or even act as a firebreak, depending on other conditions.
