The transportation process of demolition materials in nearly all industries creates pesky dust. At concrete crushing facilities, dust is generated at multiple points. Front end loaders, hoppers, and conveyor discharge points all bring dust when operational. Front end loaders transfer the incoming demolition materials to the hopper.

MSHA will allow independent contractors who work at both Part 46 and Part 48 surface mining operations to comply with the training requirements of Part 48, instead of complying with both training rules. This will eliminate the need for developing two training plans and complying with two record-keeping requirements.

Types Of Dust. Fibrogenic dust, such as free crystalline silica (FCS) or asbestos, is biologically toxic and, if retained in the lungs, can form scar tissue and impair the lungs' ability to function properly. Nuisance dust, or inert dust, can be defined as dust that contains less than 1% quartz. Because of its low content of silicates, nuisance.

The intent is to have the droplets collide and attach themselves to the dust particles, causing them to fall from the air. In these cases, droplets in the range of 10 to 50 microns have been shown to be most effective [Bartell and Jett 2005]. Uniformity of wetting is also a very important issue for an effective system.
