Five Deer Park workers have been taken to hospital in a stable condition following exposure to an unknown chemical at a factory this morning.
Fire crews have hosed down three men exposed.
The men were reportedly working at a factory site on Foleys Road when a pipe burst, showering them in an unknown chemical.
An MFB spokesman said the chemical is still unknown.
Three men, aged 40, 44 and 50, remain in a stable condition in Footscray hospital.
Two men, a 41-year-old and a 44-year-old, have since been discharged from Sunshine Hospital.
The premises has been evacuated and Foleys Road is closed near the scene.
