Pesticides should NOT be stored in a ______ building.

Pesticides should not be stored in an unlocked building because security is a critical concern when handling these substances. Unlocked storage areas could lead to unauthorized access, creating significant risks for human health and the environment. Properly securing pesticide storage helps prevent accidental exposures, spills, or theft, which could lead to misuse or environmental contamination.

In contrast, locked buildings provide a secure environment, while ventilated and refrigerated spaces offer appropriate conditions for maintaining pesticide effectiveness and safety. Each of these latter options is intended to ensure that pesticides are protected from degradation and are stored in a manner that reduces risks associated with their volatility or toxicity.
