Air testing found no asbestos present where dust fell on a patient in Australia's Royal Hobart Hospital's intensive care unit, according to an article on the ABC News website.
The incident happened after a sub-contractor working on the roof of the hospital dropped ducting, which caused a metal ceiling tile in the ICU to move.
The incident comes almost two weeks after asbestos fell from the ceiling in a different hospital building, forcing the relocation of 40 staff.
"Redeveloping the current hospital and ensuring that services continue clearly is showing to be a more difficult ask of both the hospital and of the redeveloper," according to a spokesman from the Health and Community Services Union.
