JUNEAU, Alaska (AP) - The airport serving Alaska's capital city doesn't have to worry about bears coming around anytime soon.

Juneau International Airport had to be evacuated Friday afternoon because of an accidental discharge of anti-bear spray.

The chemical comes in a canister like pepper spray but is used to defend against attacking bears.

Fire Chief Eric Mohrman says the spray spread through the building via the ventilation system. The terminal had to be cleared and the building aired out. One person was taken to a hospital for evaluation.

The airport reopened after about an hour and a half.
