What is the primary function of a pesticide application ventilatory system?

The primary function of a pesticide application ventilatory system is to provide fresh air supply. This system is crucial for maintaining a safe breathing environment for the applicator during pesticide application. By ensuring a constant flow of fresh air, it helps to dilute and remove potentially harmful airborne contaminants, including pesticides, thus reducing the risk of inhalation exposure.

While filtering harmful chemicals might seem relevant, the ventilatory system primarily functions to deliver fresh air rather than to filter out residues. This allows the applicator to work more safely in environments where pesticides are being applied. Preventing pesticide drift is also an important consideration when applying pesticides, but it is usually managed through application techniques and equipment rather than a ventilatory system. Similarly, while cooling the applicator may be a minor benefit of increased air flow, that is not the primary purpose of such a system.
