Which statement about pesticide storage facilities is true?

Choosing the appropriate storage site for pesticides is crucial for safety and efficacy. Terrain plays a significant role in this decision. Factors such as drainage, accessibility, and potential environmental impact must be taken into account to ensure the facility is situated in a safe location. For example, selecting a site that is elevated and away from water sources can help prevent contamination from spills or leaks. Additionally, it is vital to avoid high-traffic areas or locations that are prone to flooding, as these factors can pose risks to both human health and the surrounding ecosystem.

The other statements do not align with best practices for pesticide storage. For instance, a ventilation system should not vent air into an adjoining room, as this can compromise safety by spreading harmful vapors rather than controlling them. Keeping the floor as bare soil is also not advisable, as it can lead to absorption of spills and make cleaning difficult; a solid, impermeable surface is preferred. Finally, storing pesticides in direct sunlight is discouraged because it can lead to temperature fluctuations that might degrade the chemicals or create pressure build-up in containers.
