What is the main purpose of using a face shield while applying pesticides?

Using a face shield while applying pesticides is primarily about safety, specifically aimed at preventing eye and face exposure to harmful chemicals. Pesticides can be quite hazardous and might cause serious injury if they come into contact with the eyes or skin. A face shield acts as a barrier against splashes, mists, or any accidental spills that could lead to exposure, which is crucial in maintaining the health and safety of the applicator. This protective gear is an essential component of personal protective equipment (PPE), designed to minimize the risk associated with pesticide use in various agricultural and pest control scenarios.

In addition, while visibility is important for proper application, the main focus of a face shield is clearly about preventing exposure rather than enhancing visibility or addressing sound, which are not relevant to the inherent risks involved in pesticide application.
