Why are construction workers given milk?

As a young man, I recall seeing painters at construction sites being given milk at the end of the working day, to ostensibly “wash down the paint fumes in the chest.” Little did it occur to all concerned at the time that this milk would only succeed in washing down any residual fumes in the throat, leaving the bulk of it travelling down to the respiratory system throughout the working day.
