Which route of exposure involves substances entering through the skin or eyes?

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

Answer: (C)

The correct answer, which identifies the route of exposure through the skin or eyes, is absorption. This route refers specifically to the process where hazardous substances penetrate the skin or mucous membranes and subsequently enter the body. Absorption can occur through direct contact with liquid, solid, or even gaseous forms of a hazardous material, emphasizing the critical need for personal protective equipment when handling such substances.

Understanding absorption is vital in hazardous materials response because it highlights the risk that toxic agents can pose even without inhalation or ingestion. The skin is a significant organ for absorption, meaning that even minimal contact can lead to harmful effects, making awareness and preventive measures essential during HAZMAT situations or when dealing with chemicals in various settings.
