What are the signs of a potential fire hazard?

The identification of potential fire hazards is crucial in maintaining safety in any environment. The correct choice highlights specific indicators that are well-known to increase the risk of a fire. Blocked exits can prevent safe evacuation during an emergency, while frayed wires can lead to electrical shorts and ignite fires. Additionally, the improper storage of flammable materials can create an immediate combustion risk, especially in environments where sources of ignition may be present. Recognizing these signs allows for proactive measures to be taken to mitigate potential dangers.

Other choices do mention factors that could be associated with fire hazards, but they do not encapsulate the core signs as effectively. For instance, low electricity bills may not clearly relate to fire hazards, while presence of smoke and loud alarms are more indicative of an existing fire rather than potential hazards. Similarly, frequent power outages and dim lighting may suggest electrical issues but do not directly point to signs of a potential fire hazard like the specific conditions described in the correct choice.
