Mr Andrews said the risk to those at the site now was low because of remediation works.
He has asked that the Monash University report findings be included in a parliamentary inquiry into Fiskville, the terms of which are expected to be finalised in February. The United Firefighters Union says the study is vindication for the union and former CFA fire chief Brian Potter who fought to expose the dangers of the site in the years before his own death from cancer in 2014.
"When Brian Potter died the former government still clung to the fiction that Fiskville was safe and they refused to recognise his cancers as work-related or to support him and his family," union spokesman Mick Tisbury said.
He said those who sent firefighters to the site had no choice now but to resign.
