A chemical can enter the body by different ways. Four main routes chemicals can enter the body are:

  • Inhalation
  • Dermal exposure (skin)
  • Ingestion (oral)
  • Injection

--Air can be contaminated and can be inhaled. When air is inhaled it goes through the mouth and nose then into the lungs.

--When chemicals are touched the chemical can go through the skin and into the bloodstream.

--Chemicals can be accidentally swallowed
if food, cigarettes, or if your hands are contaminated.

--Injection is one way that chemicals enter the body. In some workplaces they have sharp objects which can punctures the skin and can inject a chemical or virus directly to your bloodstream.
