Why should you not use lighter fluid for charcoal after it is lit?

Using lighter fluid on charcoal that is already lit can create dangerous flare-ups and even potential explosions. When lighter fluid is applied to burning charcoal, it rapidly ignites and can create a sudden, intense burst of flames. This dramatic increase in fire intensity poses a serious safety risk to anyone nearby and can cause burns or other injuries.

The volatility of lighter fluid means that it can ignite quickly and unpredictably when exposed to existing flames, leading to a hazardous situation. It is essential to always adhere to safe grilling practices, which include allowing the charcoal to ignite naturally or using chimney starters, rather than introducing additional flammable substances once the fire is already established.

The other options may reflect some potential issues related to grilling, such as flavor or cooking efficiency, but they do not capture the immediate and serious safety risks that arise from using lighter fluid on lit charcoal. The primary concern should always be ensuring safety when grilling.
