Abstract
A mobile barrier for use in wind control, reduction of blowing litter and suspension and transport of airborne contaminants with applications in areas of landfill maintenance, agriculture, erosion control, and snow control is described. The mobile barrier is a large mesh panel supported in an orientation that is at a slight angle to the vertical. The panel is supported using a pair of upright members that extend upward from a base which is freestanding. A vertically adjustable lifting boom is also supported by the upright members, and is used to secure the mobile barrier to lifting machinery for purposes of transport. Further, a system for controlling the spread of wind-borne contaminants will be described which includes a mobile barrier in combination with a misting device.
