Insecticides/pesticides may be stored in all ways except:

Storing insecticides and pesticides safely is crucial to prevent contamination and potential harm to human health and the environment. The correct response indicates that these substances should never be placed above dishwashing sinks. This practice poses a contamination risk; if any leaks or spills occur, the chemicals could easily drip into the sink, contaminating utensils, dishes, or food used in the kitchen. Additionally, the area above sinks is often high-traffic, which increases the risk of accidents.

In contrast, the other storage options reflect safer practices. For instance, a metal locked cabinet provides a secure way to store these chemicals, limiting access and reducing the risk of accidental exposure. Storing pesticides on the lowest shelf is also preferable, as this minimizes the chance of falling or spilling onto other items, particularly food. Lastly, keeping these substances in the basement, away from food and other chemicals, further enhances safety by segregating hazardous materials and preventing cross-contamination.
