A smoking heater at the Bellevue Hyatt forced the evacuation of several hotel guests Tuesday morning, according to KOMO TV. No one was hurt.

A report at 6:30 a.m. said smoke was coming from a wall heater in a 16th floor room. When firefighters arrived, hotel maintenance staff had already used a fire extinguisher on the unit and there were no flames.

Because of smoke on the floor, firefighters briefly evacuated some hotels guests until the smoke could clear.
