This is the most hazardous activity of pesticide use.

• A. Applying pesticides
• B. Cleaning up spilled pesticides
• C. Disposing of containers
• D. Mixing and loading pesticide

Answer: (D)

Mixing and loading is the most hazardous activity because you’re handling concentrated pesticide products directly, before they’ve been diluted for use. The transfer process—measuring, pouring, and filling spray tanks or equipment—creates the greatest opportunity for exposure through skin contact, eye exposure, and inhalation from vapors or dust. A small spill or splash can deliver a large dose of active ingredient to the handler, and improvised or rushed mixing increases the risk. In contrast, applying pesticides typically involves diluted product and some distance from the treated area, with exposure more managed by application equipment and drift controls. Cleaning up spills is dangerous but usually occurs with spill-response procedures and PPE in place, and disposing of containers (when empty) generally presents less exposure than handling concentrated product during mixing and loading.
