Which is not a recommended safety precaution for a pesticide storage facility?

• A. Store glass or pressurized containers in sunlight
• B. Install leak detection and ventilation
• C. Use secondary containment
• D. Conduct routine inspections

Answer: (A)

Pesticide storage safety focuses on controlling heat, vapors, and leaks to prevent accidents. Storing glass or pressurized containers in sunlight goes against that goal. Heat from sunlight raises the internal pressure of sealed and pressurized containers, increasing the risk of leaks or a rupture. Glass can also crack or shatter under thermal stress or impact, creating spills and exposure hazards. Direct sun can also degrade labels and packaging, making hazards harder to read and increasing the chance of mishandling.

Safe storage, instead, uses a cool, dry, well-ventilated area away from heat and ignition sources. It relies on secondary containment to catch leaks, leak detection and ventilation to manage vapors, and routine inspections to spot damaged packaging, mislabeled products, or other hazards before a spill occurs. The other precautions—installing leak detection and ventilation, using secondary containment, and conducting routine inspections—are aligned with good safety practice and help reduce risks in a pesticide storage facility.
