Over the years, the field of unconventional weapons, including chemical weapons, has evolved.

Chemicals are designed to harm the human body. The severity of the harm is directly related to the concentration of the chemical to which the individual is exposed, and the duration of the exposure.

There are four possible ways to come in contact with a chemical:

· Through the respiratory system.

· Through the eyes.

· Through the digestive tract.

· Through skin contact.

Eye contact and inhaling the chemicals through the respiratory tract are often more severe than contact through skin or through the gastrointestinal tract.

Individuals who are injured in chemical attacks should be removed from the scene as quickly as possible.
