Which of the following actions can help prevent a fire on the range top?

The action of never leaving cooking unattended is crucial in preventing a fire on the range top. When cooking, it's essential to stay close by to monitor the situation, as food can quickly overheat, leading to smoke or flames. Unattended cooking is a significant risk factor for kitchen fires, as it allows the heat to build up uncontrollably, especially with oil or grease, which can ignite.

Maintaining attention on the cooking process allows for immediate action if something starts to overheat or burn, such as smothering a flame with a lid or removing the pan from the heat source. This vigilance greatly reduces the risk of a fire occurring in the first place.

In contrast, keeping flammable items nearby poses a direct risk, as they can catch fire if exposed to heat or flames. Using a non-stick pan, while beneficial for easier cooking and cleanup, does not directly prevent fires. Wet towels can cool pans but can also create additional hazards, such as steam or adding moisture to a fire, leading to dangerous flare-ups.
