Which statement lists all routes of exposure described for hazardous materials?

• A. Inhalation only
• B. Absorption only
• C. Ingestion, injection, inhalation, and absorption
• D. Ingestion and inhalation only

Answer: (C)

Understanding all routes of exposure is crucial because it guides protective measures and decontamination decisions. Hazardous materials can enter the body in several ways, and the four described routes are inhalation (breathing in fumes or dust), ingestion (swallowing material that has contaminated hands or food), dermal absorption (skin contact allowing the substance to pass into the body), and injection (entry through puncture or needle injuries). The statement that lists all four routes is the best answer because it fully describes every way exposure can occur. Other options only mention a single route or omit some routes, which would not capture all the ways someone could be exposed.
