The McGowan government has been accused of complacency after staff at Royal Perth Hospital were put at risk of exposure to COVID-19.
An investigation is continuing into the infection-control breach involving the captain of the AquaGenie bulk iron ore carrier.
A service lift was not properly cordoned off after it was used to transport the man in his 60s from the RPH emergency department to the intensive care unit on Saturday.
'Review of CCTV footage has identified that three staff members, who were not wearing PPE, unknowingly entered the lift within 15 minutes of the patient transport, prior to it being cleaned,' East Metropolitan Health Service Chief Executive Liz MacLeod said.
