Simplify the following text for a Grade 9 native English-speaking person.
Original: Asbestos is a natural mineral .
Simplified: In older buildings ( e.g. those built prior to 1999 in the UK , before white asbestos was finally banned ) , asbestos may still be present in some areas e.g. old bath panels , concrete water tanks and many other places . Being aware of asbestos locations reduces the risk of disturbing asbestos .
