Structural Pest Control Applicator Practice Exam

Which two routes of entry are likely to be the most important to a structural pest control applicator?

1. Dermal and oral

2. Dermal and inhalation

3. Inhalation and oral

4. None of the above

The correct answer is: Dermal and inhalation

The most important routes of entry for a structural pest control applicator are dermal and inhalation. Understanding these pathways is crucial for ensuring safety while handling pesticides and other chemicals. Dermal exposure occurs when substances come into contact with the skin. Applicators often handle various pest control products, and if proper protective gear is not used, chemicals can be absorbed through the skin, leading to potential health hazards. For instance, pesticides may penetrate through the skin's outer layer, posing risks to the applicator's health. Inhalation is another significant route of exposure, as many pesticides are designed to be applied in a manner that allows them to become airborne. When dissolved in solvent or dispersed in air, these substances can be inhaled during application or when working in areas that have been treated. Inhalation can result in acute or chronic respiratory issues, making it essential for applicators to use appropriate respiratory protection. While oral exposure is also a concern, it is generally less common and mitigated through safe handling practices in the workplace. Therefore, emphasizing protection against dermal and inhalation risks provides a comprehensive approach to safeguarding applicators’ health while they perform their duties.
