MORE than 20 fire trucks were at the scene of a Keysborough factory fire this morning.
CFA crews were called to Australia Magnum Trading in Cambria Drive shortly before 4am.
Shortly after 7am, a CFA spokeswoman said the fire was contained to an area about 50 metres by 30 metres but still fully involved.
Roads around the site are closed.
The Journal understands the factory is filled with plastic car bodies.
The fire authority has issued an advice warning for Keysborough and surrounds, urging people to stay indoors to avoid thick smoke from the blaze.
