Which statement is true about storage of pesticide containers?

• A. Place bulk or min-bulk tanks on a reinforced concrete pad or other impermeable surface
• B. Store containers on a wooden pallet in direct sun
• C. Keep containers in a damp, unventilated closet
• D. Use metal drums without any pad

Answer: (A)

Placing bulk or min-bulk pesticide tanks on a reinforced concrete pad or other impermeable surface is the best practice because it provides a solid, non-porous barrier that prevents leaks and spills from soaking into soil or reaching groundwater. This containment makes cleanup easier and reduces environmental risk, which is a central goal of safe pesticide storage.

Storing on a wooden pallet in direct sun allows heat buildup, which can degrade containers and contents and increase the likelihood of leaks or volatilization. Keeping containers in a damp, unventilated closet fosters moisture-related problems, corrosion, and potential buildup of fumes. Using metal drums without any pad offers no containment for leaks, so any spill can seep into the ground.
