Inhalation exposure involves what?

• A. Breathing vapors or dust
• B. Skin contact
• C. Eye exposure
• D. Swallowing pesticide

Answer: (A)

Inhalation exposure means the chemical enters the body through the respiratory system by breathing in vapors, mist, aerosols, or dust. This route allows the substance to reach the lungs and then the bloodstream, which is why inhalation can cause rapid and sometimes widespread effects, especially with volatile pesticides or fine dusts. In pest management, this exposure is common when products are sprayed indoors or without adequate ventilation, so using proper ventilation and protective respirators reduces risk.

Dermal exposure involves skin contact. Ocular exposure occurs through the eyes. Oral exposure happens if the substance is swallowed. Each of these is a different route of exposure, not inhalation.
