Parents have voiced their concerns as it emerged a north primary school building contains asbestos.
The roof of an old classroom at tiny Marybank Primary School near Muir of Ord has apparently been a concern for years.
Parents had not been informed about the remedial work to prevent the dangerous substance from reaching the playground.
Highland Council claimed the danger posed is “negligible” and “steps have been taken” to limit what does come off the roof.
The company removing the asbestos from the play area are using workers sent in with protective clothing.
The chairwoman of the parent coucil, Carol Hayllam, said parents should have been known about the issue in advance to make “informed decisions”.
She said: “If it wasn’t a risk it would not have to be cleared up, would it? If we had the information then would have had the ability to allow the parents to make their own decisions.
“Having had no information from the council I can’t speak to the issue but when we get information from the council we would look further into it.
“I understand that the Highland Council is sending out information to parents now.”
The remedial work had been carried out during the holidays but now that term has started it is not clear how the asbestos will be removed when work is to begin replacing the roof in October.
A Highland Council spokeswoman said: “The Council has employed specialist contractors to inspect and make safe the roof at Marybank Primary School.
“The risk posed by flakes of asbestos cement coming off the roof is negligible and steps have been taken to erect boxing around the eaves to prevent further moss blowing off, until the roof is replaced in October 2018.
“Specialist contractors who attended the school (by requirement of their employment) wore protective clothing.
“A two part process of putting up the boarding and cleaning the playground area took place over the holidays while the school was closed.”
