In a correctional facility, contamination from hazardous materials can occur through four routes. Which set lists all four?

• A. Inhalation, digestion, absorption, and exhalation
• B. Inhalation, ingestion, absorption, and injections
• C. Contact, exposure, respiration, and evaporation
• D. Ingestion, excretion, respiration, and osmosis

Answer: (B)

Understanding routes of exposure means recognizing the four primary portals by which hazardous materials can enter the body in a facility: inhalation of contaminated air, ingestion by swallowing, absorption through skin or mucous membranes, and injection through a puncture or needle. This set—inhalation, ingestion, absorption, and injections—directly maps to those four entry paths, so it best represents all the ways contaminants can get into a person. The other options mix terms that aren’t entry routes into the body. Exhalation is breathing out, not bringing hazards in. Digestion is the process after ingestion, not a separate entry route. Terms like contact, exposure, respiration, evaporation, excretion, or osmosis describe processes or outcomes rather than the four portals of entry.
