Starting on Tuesday, Beaverton authorities will begin enforcing an ordinance that outlaws Airsoft guns, which look like real firearms but use compressed air to shoot plastic pellets, in public places.

The ordinance went into effect on March 31 and was followed by a 30-day public information campaign before the actual enforcement begins on May 1.

The Beaverton Police Department distributed brochures to schools and businesses in the Beaverton area that sell Airsoft replica guns that explains the dangers of using the firearms in an unsafe manner.

Beaverton is the first city in Oregon to adopt the ban.
