Which statement correctly identifies a general route of entry not listed in the standard hazmat pathways?

• A. Inhalation
• B. Ingestion
• C. Absorption
• D. Dermal

Answer: (C)

The general routes of entry used in hazmat awareness are inhalation, ingestion, and dermal contact. Absorption is the process by which a chemical moves from the surface (often the skin) into the bloodstream, not a separate route of entry. So while a chemical can be absorbed after dermal exposure, absorption itself isn’t listed as one of the standard entry pathways. The other options—inhaling to enter via the lungs, ingesting to enter via the digestive system, and dermal contact to enter through the skin—are the actual routes recognized in hazmat training.
