How can you protect workers from exposure during mixing and loading operations?

• A. Do not restrict access to mixing area
• B. Share PPE between employees without cleaning
• C. Use enclosed or well-ventilated mixing areas, wear appropriate PPE, keep non-essential personnel away, and practice good hygiene and decontamination
• D. Allow unventilated mixing to save energy

Answer: (C)

Controlling exposure during mixing and loading centers on reducing contact with pesticides through engineering controls, proper PPE, restricted access, and good hygiene. Using an enclosed or well-ventilated mixing area limits vapor and aerosol buildup around workers. Wearing the appropriate PPE—such as gloves, eye protection, and any respirator required by the product label—provides a personal barrier against skin contact and inhalation. Keeping non-essential personnel away minimizes the number of people exposed and reduces the chance of accidental exposure. Good hygiene and decontamination, including washing exposed skin, changing or cleaning contaminated clothing, and cleaning tools and surfaces, prevents residues from spreading and being carried home. Together, these practices address multiple routes of exposure and align with label requirements. Options that allow unrestricted access, sharing PPE without cleaning, or mixing in unventilated spaces fail to reduce exposure and are unsafe.
