Which of the following is a common fire hazard?

Faulty electrical wiring is a recognized common fire hazard due to its potential to overheat, short circuit, or fail, which can easily lead to an electrical fire. When electrical systems are not properly installed or maintained, they can create arcs or sparks that ignite surrounding materials, particularly flammable ones. This risk is exacerbated in environments where older wiring or inadequate insulation exists, significantly increasing the likelihood of a fire breaking out.

Understanding the implications of faulty wiring can help security personnel recognize warning signs such as flickering lights, frequent breaker trips, or unusual odors, enabling them to act promptly to mitigate fire risks. Familiarity with such hazards is crucial for ensuring the safety of the environment they are tasked with protecting.
