• A. In original labeled containers, closed tightly, stored away from food, children, and water sources; use a secure, ventilated area; secondary containment if required.
• B. Store pesticides in a locked metal cabinet next to the laundry room.
• C. Keep pesticides in a locked plastic bag in an open area.
• D. Store pesticides in unlabeled containers in an open area.

Answer: (C)

Safe pesticide storage relies on keeping products in containers that are intact and clearly labeled, and placing them in a secure, ventilated area away from anything that could be contaminated or damaged. The best practice is to store pesticides in their original labeled containers, closed tightly, in a locked, ventilated area with secondary containment if required. This preserves the identity and hazard information, reduces the chance of leaks, and limits access to keep spills from spreading and contaminating soil, water, or foods. Storing in a locked plastic bag in an open area misses those protections—bags can puncture or leak, labeling may be unclear or lost, and an open area can expose contents to weather and unauthorized people, increasing the risk of spills and contamination. Always keep pesticides away from food, children, and water sources and use secondary containment when recommended.
