Why is it important for applicators to regularly perform seal checks on respirators?

To improve airflow
To ensure a proper fit
To clean the filters
To determine if they need lubricant

The correct answer is: To ensure a proper fit

Regularly performing seal checks on respirators is crucial for ensuring a proper fit. A well-fitted respirator forms an airtight seal around the face, which prevents contaminants from leaking in through gaps. This is particularly important when handling pesticides and other hazardous materials, as any breach in the seal can expose the applicator to harmful chemicals, undermining the protective capabilities of the respirator. A correct fit also enhances overall comfort and effectiveness, allowing the user to safely yield the necessary productivity without compromising health. The other options do not specifically address the primary reason for conducting seal checks. Improving airflow, cleaning filters, or determining the need for lubricant are important for respirator maintenance but do not directly relate to ensuring that the respirator performs its fundamental role of filtering out harmful substances due to a proper fit.
