When did the legal requirement for the double bagging of asbestos waste (red inner/clear outer plastic bag) come into force?

It is difficult to say exactly when the bagging arrangements came into force. However, we would imagine it would have been in 1983 when the asbestos licensing regulations came into force and legislation tightened for those removing asbestos. Bearing in mind that the UK was still importing and using asbestos at that time.
