The general routes of entry for human exposure to hazmat are:

Explanation:
Exposure to hazmat can enter the body through four main routes: inhalation, ingestion, absorption through the skin, and injection. Inhalation is common for gases, vapors, and aerosols; ingestion happens when contaminated hands or food/water are swallowed; dermal absorption occurs when skin contact allows the substance to pass through; injection is possible through punctures or needle sticks or contaminated sharps, introducing material directly into the body. The other options mix terms that aren’t definitive entry routes (like external exposure or vague “contact”) and don’t distinctly include the injection pathway, which is essential to complete the four entry methods.
