Tear gas is a chemical weapon that causes irritation to the eyes, skin, and respiratory system. It is often used by law enforcement to disperse crowds. Exposure to tear gas can be dangerous, and it is important to know how to avoid it.
There are a number of ways to avoid tear gas. One way is to wear a gas mask. Gas masks can be purchased at most hardware stores. Another way to avoid tear gas is to stay away from areas where it is likely to be used. If you are caught in an area where tear gas is being used, try to move to a higher elevation. Tear gas is heavier than air, so it will sink to the ground. You can also try to find a place to take cover, such as a building or a car.
