Tony, would it be beneficial to look at the process or work flow as a
whole to see if it can be 're-engineered'?
You asked if the finer mesh is worth the effort. I'm unsure about that
as I don't have a comparison between the two. Definitely a good
question that may make additional exposure to fine dust unnecessary.
But if you do require the additional processing, you may want to examine
how it's done and if the hazards can be minimized by:
- automating the process without direct human contact;
- containing the dust particles by grinding in a wet state;
- use positive airflow respirators (mentioned by Evan Dresel);
- use a constant directed air flow through the work area (like working
in a huge spray booth or hood vent);
These are just a few ideas that you may want to run by a qualified
engineering type.
All the Best
