SEATAC, Wash. -- Multiple fire trucks and ambulances responded at Sea-Tac Airport after passengers were exposed to fumes from a de-icing solution inside an airplane Wednesday morning, airport spokesman Perry Cooper said.

Paul McElroy from Alaska Airlines said crews were de-icing the plane for flight 528 to Burbank, Calif. when passengers on board reported smelling fumes and having eye irritation.

KIRO 7 News producer Katie Haynes was inside Sea-Tac Airport and talked to a passenger who was on the flight.

Joe Dial of Seattle said the plane pulled away from the gate at about 7 a.m. when the pilot announced that they had to return to the gate for de-icing. During the de-icing, Dial said the fumes started coming in to the cabin.

Dial said the pilot announced that the smell was de-icer and that they would have to stop the flight.

Dial said the passengers were exposed to the fumes for 45 minutes before they were able to get off the plane.

Alaska Airlines spokesman Caroline Boren said paramedics treated 26 people and seven -- all five crew members plus two other airline employees on board -- decided to go to a hospital. Boren said it was unknown how the fumes entered the plane.

The seven who were transported to Highline Hospital in Burien were treated and released.

Boren says all 143 passengers decided to board another plane and continue their flight.

No one was seriously injured.
