Firefighters from seven CFA brigades responded to a factory fire in Knoxfield this morning.
The fire broke out just after 8am this morning at a cardboard manufacturing facility on Ferntree Gully Road near Stud Road, Knoxfield.
The fire was deemed under control at 9.25am.
Five CFA pumpers from Rowville, Boronia, Bayswater, Scoresby and Ferntree Gully, a CFA ladder platform from Dandenong and two MFB appliances responded to the fire, with firefighters requiring breathing apparatus to fight the fire.
District 13 Rostered Duty Officer Andrew Booth said it hadn't been a big fire, but a complex situation due to access issues.
The fires had started in an extraction system 3-4 storeys up, requiring a ladder platform to access.
"The fireys have done a great job to contain it to one building and to the extraction system," Mr Booth said.
Firefighters had to ensure no smouldering materials had made their way into the piping system before the job was declared safe.
Ambulance Victoria attended to monitor the health of firefighters, but there were no incidents.
Factory staff self-evacuated as per fire safety procedures and were gathered at an assembly point when firefighters arrived.
"It makes our job much easier, knowing that we're not missing anyone," Mr Booth said.
