Which of the following are routes of entry for hazmat besides inhalation?

• A. Ingestion only
• B. Absorption only
• C. Injection only
• D. Ingestion, absorption, injection, all of the above

Answer: (D)

Beyond inhalation, hazmat exposure can occur through ingestion, absorption, or injection. Ingestion happens when a contaminated substance is swallowed, often due to touching the mouth with dirty hands or eating and drinking in a contaminated area. Absorption means the chemical passes through the skin or eyes; many hazmats can penetrate skin, especially liquids or powders on exposed areas. Injection occurs if a contaminated object, like a needle or sharp, penetrates the skin, delivering the substance directly into the body.

Because all of these routes are possible, the option that lists ingestion, absorption, injection, and all of the above is the best answer. It reflects that routes of entry beyond inhalation include multiple pathways, not just one.
