Children exposed to toxic, coloured sand that’s forced dozens of schools to close face an extremely low risk of asbestos contamination, an expert says.

Experts have downplayed the risk to children as early childhood centres and schools around Australia are removing and disposing of coloured sand products with trace amounts of asbestos.
More than 70 public schools across Australia were closed on Monday due to the potential contamination.
In a recall notice published on Sunday, the Australian Competition and Consumer Commission (ACCC) said laboratory testing had detected asbestos in some samples of Kmart Australiaâs Active Sandtub 14 piece Sand Castle Building Set, sold at both Kmart and Target, and Magic Sand tubs in blue, green and pink, that were only sold at Kmart.
It warned the products âmay cause a risk to healthâ, though the chance of children inhaling airborne asbestos from them was low.
Sundayâs warning came after more than a dozen primary and preschools in the ACT were fully or partially closed last week after the ACCC on Wednesday recalled another range of childrenâs sand products, two supplied by local wholesaler Shamrock Australia and the other two by art supplies company Educational Colours.
A Brisbane school was closed on Friday while another was identified with the affected product, the Queensland government said.
Some school closures could last days.

Despite the precautions, families have been told they shouldnât be alarmed by the asbestos scare.
Asbestos is a âdeadly dustâ and exposure to even a small amount can lead to terrible consequences, the Asbestos and Dust Diseases Research Instituteâs Anthony Linton said.
But asbestos did not appear to be airborne in the latest scare which helped minimise the risk, he said.
âThey (people) are absolutely right to be nervous, but ⌠it feels as though very much that this asbestos is within the sand itself,â Linton said.
âSo it is not particles floating through the air that is going to be breathed into the lungs.â
It was too early for parents to look for symptoms of asbestos exposure in their children and there was no simple test for it, Linton said.
The contamination risk for the children and adult teachers exposed to the sand across dozens of schools was considered âvery lowâ.
âHowever, you can never say 100 per cent and thatâs why the appropriate amount of caution is essential,â he said.
People who find the sand product at their homes should dispose of it properly to avoid a repeat of the Sydney asbestos crisis, when asbestos-contaminated mulch was found across dozens of parks, schools and other public NSW sites in 2024.
âThere has been cases where people will throw asbestos into green bins that then get processed and turned into mulch,â hazardous materials management firm EDP Consultantsâ John Batty said.
âWe donât want these products getting back into the community,â Batty explained.Â
People should double bag the product, seal it with strong tape and label it âdo not openâ before visiting the Asbestos and Silica Safety and Eradication Agency website for more information.
Asbestos removal contractors worked over the weekend to remove sand from ACT schools.
Licensed asbestos contractors will test, remediate and clear the spaces for use again, the ACT government said.
âAll of the air testing that our contractors have done across public schools so far has been negative to airborne asbestos.â
Safety alerts have been issued in nearly every state and territory urging schools, consumers and service providers to stop using the sand products.Â

Products linked to the asbestos scare have been identified at more than 140 sites in South Australia, with hazard alerts issued but no schools closed.
The product found at ACT schools was imported from China and sold as Kadink Decorative Sand in tubes weighing 10 grams, Worksafe ACT said.
It comes after a national recall of childrenâs sand products sold at retailers including Officeworks, Educating Kids, Modern Teaching Aids and Zart Art.
Spin Master, a toy maker, said its popular Kinetic Sand was not subject to the recall and remains safe for use.
