Asbestos dust and fragments left littered across a Sydney private girls' school, have raised health concerns for students and local community members.

Asbestos removal works were undertaken in an old swimming pool change room at St Catherine’s School Sydney in Waverley over the weekend with both the work site, outside footpath and street left scattered with the deadly material.

NSW CFMMEU secretary Darren Greenfield said the work undertaken shows disregard for necessary safe handling and disposal processes of asbestos.

“It is shocking to see such blatant disregard for the safety of the community,” Mr Greenfield said in a statement on Tuesday.

“There is asbestos dust everywhere and the clean-up effort at the site has been rudimentary at best.”

St Catherine’s School Sydney and the CFMMEU confirmed the work was undertaken by Richard Crookes Construction.

Mr Greenfield said the union has called for a hygienist to assess the site and is urging SafeWork NSW to conduct a thorough investigation.

“This should serve as a warning to the whole community that there are no short cuts to safely handling asbestos,” he said.

“Our community is riddled with this deadly toxin and it is imperative that safety comes first whenever it is discovered.”

A SafeWork NSW spokesman says investigations into the improper asbestos removal process at the school are currently under way.

Richard Crookes Construction were contacted for comment, but did not respond before publication.
