What must be true when crossing an open body of water with pesticide equipment?

• A. Only use water-based formulations.
• B. No precautions are required beyond basic safety.
• C. The pesticide concentrate must be in a secured, leak-proof secondary container, and spray equipment must be kept above the water.
• D. Must notify authorities prior to crossing.

Answer: (C)

Crossing an open body of water with pesticide equipment requires containment and proper positioning to prevent environmental contamination. The pesticide concentrate must be secured in a leak-proof secondary container, so any leaks or drips are contained and cannot enter the water if something shifts or damages during transit. Additionally, keeping the spray equipment above the water reduces the risk of spills or gear-related leakage reaching the water if the vessel rocks, tilts, or encounters a leak. These steps protect waterways and align with responsible pesticide handling during transport. The other considerations listed aren’t the controlling safety requirements here—the focus is on containment and keeping equipment out of the water, not on formulation type, extra precautions beyond standard safety, or notifying authorities for crossing.
