Tear Gas

Tear gas is a term used to refer to several different riot control agents that temporarily constrain people by causing irritation to the eyes, mouth, throat, lungs, and skin. Tear gas effects usually last 15-30 minutes after a person has left the exposure area and cleaned off. Examples of tear gas chemicals include chlorobenzylidenemalononitrile (CS) and oleoresin capsicum (OC; pepper spray).

Does DEQ have regulatory authority over the use of tear gas?

No, DEQ does not have regulatory authority over the use of tear gas.

What do I do after exposure to tear gas? Is it bad for my health?

To learn more about the potential health impacts from tear gas, go to the Oregon Health Authority's web page on tear gas. You can also reach out to their Environmental Health Assessment Program at EHAP.info@dhsoha.state.or.us.

How does DEQ assess and mitigate the impact of tear gas to the environment?

Because DEQ does not have the authority to regulate tear gas, it cannot require any assessments or mitigating actions. However, DEQ has and continues to work with other agencies to provide input on the environmental effects of chemicals and how to mitigate them when possible.
