not occur without respiratory protection.
> Before using any respirator, be sure you have the appropriate medical clearance, fit test, and respiratory protection
training.
> Make sure that the saw you'll be using is working properly.
> Be sure to use only sharp saw blades made for cutting concrete.
> Use saws with integrated water delivery systems.
> Check to be sure that the water supply is being applied directly to the cutting surface.
> Confirm that the water flow rate is strong enough to adequately minimize visible dust emisions.

possible.
