As a escalator engineer working on the underground I find the contents of this report very disturbing . Whilst noticing the almost daily build up of dust layers behind the hoarded of escalators we have never been infomed of the dangerous content of the dust ie Silica.
I feel that management have adopted I hope they last long enough to retire attitude I for one will be constanly wearing Dust Masks from now on and can only hope the damage has not already been done.

plese do not make my e mail address public
