The Environment Protection Authority (EPA) has warned the public to stay clear of a gymnasium at Payneham, in Adelaide's east, after reports an asbestos roof had been pressure cleaned.
EPA investigators went to the Portrush Road business about 1:30pm on Thursday.
The Metropolitan Fire Service, SafeWork SA and the local council were all called to assess the situation and in a statement the EPA said a clean-up had started.
The statement also said the Goodlife Health Club would be closed until further notice.
More details are expected to be released on Friday.
