I was a Worksafe Inspector when they were refurbishing partially demolishing Fairfield.
Went there once when some sealed test tubes of unidentifiable stuff was found in the ceiling space in a rats nest.
Caused a fair bit of angst.
Apparently the contents ended up being pretty diabolical.
Ended up getting the hygienist to conduct a thorough inspection & clean up of the roof space before anyone would go back to work
