Which of the following is NOT one of the routes of entry for hazardous materials?

• A. Inhalation
• B. Infusion
• C. Absorption
• D. Injection

Answer: (B)

Infusion is not recognized as a route of entry for hazardous materials. The typical routes of entry include inhalation, absorption, and injection.

Inhalation occurs when hazardous materials in the form of vapors, gases, or dust are breathed into the lungs, leading to potential health risks. Absorption happens when hazardous substances come into contact with the skin or mucous membranes, entering the body through the skin. Injection refers to the introduction of hazardous materials directly into the body through puncture wounds or similar means, often associated with needles or sharp objects.

Understanding the correct routes of entry is crucial for safety training and hazard assessments, as it helps individuals recognize how exposure to hazardous materials can occur and informs protective measures.
