Dust-Off. Dust-Off is a brand of dust cleaner (refrigerant-based propellant cleaner, which is not compressed air and incorrectly called "canned air"). The product usually contains difluoroethane; although some use tetrafluoroethane and tetrafluoropropene as a propellant. It is used to blow particles and dust from computer, keyboards ...
Aqueous lignosulfonate solutions are also widely used as a non-toxic dust suppression agent for unpaved road surfaces, where it is popularly, if erroneously, called "tree sap". Roads treated with lignosulfonates can be distinguished from those treated with calcium chloride by color: lignosulfonates give the road surface a dark grey color, while ...
Dust abatement refers to the process of inhibiting the creation of excess soil dust, a pollutant that contributes to excess levels of particulate matter. Frequently employed by local governments of arid climates such as those in the Southwest United States , dust abatement procedures may also be required in private construction as a condition ...
Without admitting wrongdoing, the company agreed to pay a $225,000 fine, of which $75,000 will be dedicated to installing a dust suppression screen at the plant.
Fugitive dust can be controlled by the application of various chemical suppressants including lignin sulfonates, petroleum resins, latexes, salts, plastics, and wetting agents. [6] Coal dust piles have been treated with water or other chemical surfactants to suppress dust until the moisture evaporates. Other chemicals can provide protection for ...
As such, the nature of occupational dust exposures can vary greatly by chemical composition, size, concentration, and toxicity to humans. Depending on the source, dust composition can include mineral dusts, heavy metals, respiratory sensitizers (chemicals that can cause allergic reactions such as asthma), chemical dusts, molds, spores, and more.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.

Dust control is the suppression of solid particles with diameters less than 500 micrometers (i.e. half a millimeter). Dust poses a health risk to children, [12] older people, and those with respiratory diseases. House dust can become ...
