Avoid contact with your eyes. Do not use calcium chloride within 25 feet of a body of water or alder, hemlock, larch, maple, pine or ornamental trees.

According to the United States Department of Agriculture Forest Service, calcium chloride is an effective means of reducing dust and fine debris from being distributed by traffic on roads. Because it's a common salt, it is a fairly environmentally friendly solution to dust problems. Though it can cause corrosion on metal, it's not likely to damage automobiles or other forms of transportation. Calcium chloride can also be used as a deicing agent.

Step 1

Wait until a good rainfall penetrates the road or driveway surface. The rainfall will help the calcium chloride penetrate.

Step 2

Apply the calcium chloride. Follow manufacturer's directions for the rate of application, or estimate 0.5 lbs. per square yard for flake form or 0.41lbs. per square yard for pellet form.

Step 3

Soak the surface using a high-pressure hose nozzle if your area is having a dry spell.
