What is a recommended practice for electrical fire prevention?

Using three-pronged grounded plugs is a recommended practice for electrical fire prevention because these types of plugs provide a safe and secure connection to the electrical outlet. The third prong acts as a grounding mechanism, which helps to prevent electrical shocks and minimizes the risk of electrical fires that can occur due to faulty connections or short circuits. Grounding diverts excess electricity safely into the ground, reducing the likelihood of sparks that can ignite flammable materials.

In contrast, two-pronged plugs do not offer the same level of safety, as they lack a grounding feature. Options that include overloading electrical circuits or using extension cords for permanent connections pose significant risks, as they increase the chance of overheating and fire hazards. Hence, adhering to the use of three-pronged grounded plugs is crucial for enhancing safety and preventing electrical fires.
