Leave it alone: If rock containing naturally occurring asbestos is intact and undisturbed, your risk of exposure is low. Don’t blast it, crush it, or grind it up.
Have a plan: Before you disturb rock or soil that is likely to contain asbestos make sure you have an adequate plan to control and contain the dust.
Keep it wet and cap it: If the rock or dirt contains naturally occurring asbestos, keep it wet while you’re working, and seal it under a layer of clean soil and a layer of pavement, turf, or clean gravel, when you’re finished.
