A hazardous material has entered or potentially entered your body via the routes of entry. This is known as:

• A. Contamination
• B. Exposure
• C. Contact
• D. Ingestion

Answer: (B)

Exposure is the state of having hazardous material reach or be available to the body through routes of entry—such as inhalation, ingestion, absorption through the skin, or injection. When a material has entered or there is a realistic pathway for it to enter the body, it constitutes exposure because a potential dose can affect internal tissues. Contamination refers to the material being present on surfaces, skin, or clothing outside the body, not yet entered. Contact is simply being in touch with the material, without specifying that it has entered the body. Ingestion is one specific route of entry (swallowing the material), but the statement describes entering via routes of entry in general, which is best described as exposure.
