What type of exposure occurs if a chemical blows onto an operator's chest?

  1. Dermal exposure

  2. Inhalation exposure

  3. Oral exposure

  4. Ocular exposure

The correct answer is: Dermal exposure

Dermal exposure occurs when a chemical comes into contact with the skin. In this situation, the chemical is blowing onto the operator's chest, which means it is likely coming into direct contact with their skin and causing dermal exposure. Inhalation exposure would occur if the chemical were inhaled into the lungs. Oral exposure would occur if the operator accidentally ingested the chemical. Ocular exposure would occur if the chemical got into the operator's eyes. However, in this scenario, the chemical is not blowing towards the operator's face or eyes, making ocular exposure less likely.
