Measures are adopted to prevent the dust from becoming airborne. There are four preventive technologies: wetting, physical stabilization, chemical stabilization, and vegetative stabilization. Industrial operations such as mining and beneficiation, included in this study, tend to make moderate use of capture technologies.
