How should pesticides be arranged in storage?

• A. Keep dry chemicals on shelves below liquid chemicals.
• B. Store volatile pesticides with your PPE in the same area.
• C. Separate chemicals by type and isolate volatile pesticides to prevent vapor transfer.
• D. Store all chemicals together on exposed shelves.

Answer: (C)

Organizing pesticides safely hinges on separating products by their chemical type and isolating volatile pesticides to prevent vapors from moving between containers and into other products or spaces. Volatile pesticides release vapors that can travel through the air and contaminate nearby containers, cause unwanted reactions, or expose workers and surfaces. By keeping different types apart and placing volatile products in a well-ventilated, separate area, you reduce the risk of vapor transfer, cross-contamination, and exposure. Storing all chemicals together or mixing volatile pesticides with PPE increases contamination and safety hazards, while keeping dry chemicals below liquids can lead to spills or leakage.
