When applying liquid pesticides, what type of exposure is most common for applicators?

When applying liquid pesticides, dermal exposure is the most common type for applicators. This occurs because as the pesticide is being applied, it often comes into contact with the skin, particularly the hands and forearms, which can result in absorption through the skin. This method of exposure is prevalent due to the nature of pesticide application where liquid formulations can easily splatter, spill, or otherwise touch the skin.

Inhalation is also a potential route of exposure; however, it is generally less frequent than dermal exposure during the direct handling of liquids since applicators typically wear personal protective equipment such as masks or respirators to minimize inhalation risks. Oral exposure is quite rare and usually happens more through accidental ingestion of contaminated hands or food rather than during the definite application process. Ocular exposure is also a risk but less common compared to skin contact because applicators typically take precautions to protect their eyes, yet it can happen through splashes or inadvertently touching the face after handling pesticides.

Understanding the type of exposure that is most likely helps in developing appropriate safety protocols to minimize risk and protect the health of applicators.
