• A. In original containers, closed and locked, in a cool, dry, ventilated area away from food and pets; separate by hazard; keep out of direct sunlight.
• B. In any container in the garage, near food and pets.
• C. In a freezer to preserve potency, even if label advises otherwise.
• D. In open sunlit areas to preserve label clarity.

Answer: (A)

Storing pesticides properly centers on keeping them in their original containers with the label, keeping the containers tightly closed and secured, and placing them in a cool, dry, well‑ventilated area away from food and pets. This protects the product from heat, moisture, sunlight, and accidental exposure, and ensures you don’t misread instructions or confuse products. Separating by hazard helps prevent cross‑contamination or reactions if leaks occur, and makes it easier to respond safely in an emergency. Direct sunlight and high temperatures can degrade the active ingredient and alter potency, while placing pesticides in nonoriginal containers or in a freezer can change stability and safety. Storing near food or in open, sunlit areas increases contamination and exposure risk.
