One person remains missing after a factory in Melbourne's southeast, with search efforts hampered by safety concerns.
Firefighters have not yet conducted a primary search of the paint facility in Dandenong South because the structure has not been declared safe.
A building surveyor will complete an inspection before fire crews and police can enter the building.
The first fire crews arrived at the Superior Drive factory shortly after midday on Friday and immediately called for backup.
More than 120 officers and 40 trucks fought the massive blaze for hours before it was brought under control.
Three men had to be hospitalised for upper body injuries but are in a stable condition.
One person was still unaccounted for on Saturday morning, Fire Rescue Victoria confirmed.
Firefighters remain on scene to monitor any flare ups.
