What was the outcome of overheating a tank used in the manufacture of food-grade caramel coloring in April 2003?

The correct understanding of the outcome of overheating a tank used for manufacturing food-grade caramel coloring in April 2003 is that it led to a fire hazard. Overheating in industrial processes often increases the risk of combustion, especially with materials that can produce flammable vapors when subjected to excessive heat. In this case, the overheating could have caused the caramel coloring to reach temperatures where it ignited, ultimately presenting a significant fire hazard.

While option B suggests that the outcome was not related to exposing the chemical to air, this does not accurately address the fundamental issue at hand, which is that overheating itself created risks regardless of air exposure. Moreover, fire hazards arise in situations where the temperature exceeds safe limits, leading to potential ignition sources interacting with flammable substances. Therefore, understanding the dynamics of how temperature affects materials is critical in manufacturing settings.
