What is the primary reason for using a respirator while applying pesticides?

The primary reason for using a respirator while applying pesticides is to avoid inhalation of toxic fumes. Pesticides can contain volatile organic compounds or other chemicals that can be harmful when inhaled. These substances may cause respiratory irritation, other acute health effects, or long-term health issues if they enter the body through the lungs. The respirator acts as a barrier, filtering out these harmful particles and vapors, ensuring that the applicator can work safely and effectively without risking their respiratory health. Employing proper respiratory protection is essential in any application scenario, especially where there may be limited ventilation, to maintain a safe working environment.
