Re: ATM Respirator for cutting plate glass

Russell, that is a minor overkill for the need.  Even despite that, I'd use
that mask if presented to me.  It will seal a lot better than the typical
porus paper mask used for most dust conditions and the percentage of glass
getting in will be essentially 0 - the mask is more for vapor control and
thus the filtering will be better than with the single layer of the cheap
paper nose and mouth mask.
Do try to do the work outside where the wind will blow the dust away if
possible and always use water as much as possible so that when the dust does
fly, it will quickly hit the water and thus get entrapped and become
immobile.  If you have to wash the dust somewhere, wash it into good loam
type soil so that it quickly becomes interdispersed with the soil and is
captured by all of the stuff in that soil.  Washing the dust onto concrete
or a clay soil tends to keep it mobile more than into a good soil.
