CGS and the MTO present some background information on dust control in municipalities

Dust control is maintained using Calcium Chloride.  Calcium chloride is classified as a salt. Calcium chloride is non-toxic!  These two key properties of Calcium Chloride make it an excellent dust suppressant; this ability to pull moisture from seemingly dry air maintains the road at a fairly uniform level of moisture. The result is a binding effect on the fines in the gravel road, thereby stabilizing the base and preventing dust.
