Answer:
The route of entry is absorption.
Explanation:
Hazardous chemicals can enter the body of a person by processes such as inhalation, absorption, ingestion and injection.
If a hazardous chemical, such as sodium hydroxide, enters the body of a researcher through the eyes or through contact with the skin, then such a method of the entrance is termed as absorption. The epidermis and dermis layer of the skin can absorb various chemicals which will then be transferred into the bloodstream.
