What does "Route of Entry" refer to in HAZMAT situations?

In HAZMAT situations, "Route of Entry" specifically refers to the pathways through which hazardous materials can enter the body. Understanding these routes is crucial for assessing exposure risks and implementing safety measures. The primary routes of entry include inhalation (breathing in), dermal contact (skin contact), ingestion (swallowing), and injection (through punctures or breaks in the skin).

Recognizing how hazardous substances can enter the body allows responders and workers to take appropriate precautions, such as using personal protective equipment (PPE) or adopting safe handling practices to minimize exposure. This knowledge is essential for ensuring safety in environments where hazardous materials are present.
