2. Skin absorption/contact- You can come into contact with CBRN agents if they are on surfaces that you touch.

3. The mouth/swallowing – CBRN agents can be swallowed if they get onto food or airborne particles that enter the mouth.

4. Eyes – agents can get into the eyes if you are not wearing eye protection.

CBRN agents can enter the body through the skin, eyes, nose, mouth, or lungs. They can also be ingested or inhaled. Once inside the body, they can cause serious illness or death. Treatment for exposure to CBRN agents is typically limited to supportive care and decontamination of the skin and clothing. Symptoms and indicators of exposure to CBRN chemicals might be different depending on how they enter the body.
