What precautions should be taken to reduce inhalation exposure to pesticides?

• A. Open windows only
• B. Wearing goggles only
• C. Wearing a respirator and following proper safety practices.
• D. Drinking water during spraying

Answer: (C)

Protecting the lungs from pesticide exposure relies on using a respirator correctly in combination with proper safety practices. Simply opening windows or relying on ventilation isn’t reliable protection because fine pesticide aerosols can linger indoors or drift during application. A respirator provides a controlled barrier, reducing the amount of pesticide you breathe in. For it to work, you must choose the right type for the product, ensure a good fit with a seal check, and use it along with the rest of the required PPE and procedures. Follow the label directives on respirator use, maintenance, and replacement, and be trained in how to don, doff, and store the equipment. Additional steps—such as applying in ways that minimize drift (ventilation, enclosed cabs, nozzle choices), staying out of treated areas when required, and observing re-entry times—further reduce inhalation risk. Drinking water during spraying doesn’t protect the lungs and isn’t a protective measure.
