Teachers in far north Queensland will vote on Tuesday whether to take industrial action over a school asbestos scare.

Dust from holes drilled into the ceiling of a staff room at Atherton State High School, southwest of Cairns, is believed to have been falling on staff and desks for the past 18 months after work was carried out.

The room is listed in Education Queensland's asbestos register and the department restricted access to the room in late October after concerns were raised.

Samples have been taken for asbestos testing and the room was professionally cleaned this month.

Education Queensland is yet to confirm whether the samples contain asbestos.
