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 ...
Engineering controls are the third most effective member of the hierarchy of hazard controls. They are preferred over administrative controls and personal protective equipment, but are less preferred than elimination or substitution of the hazards. Controlling exposures to occupational hazards is considered the fundamental method of protecting ...
Engineering controls such as wet methods, dust collectors, and improved HVAC systems can also be highly protective. Administrative measures such as shift rotations can also help reduce personal exposures to acceptable levels. Lastly, PPE can be an effective method of helping individual workers avoid inhaling harmful aerosols.
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-laden gas or air enters the baghouse through hoppers and is directed into the baghouse compartment. The gas is drawn through the bags, either on the inside or the outside depending on cleaning method, and a layer of dust accumulates on the filter media surface until air can no longer move through it.
Engineering controls for nanomaterials are a set of hazard control methods and equipment for workers who interact with nanomaterials. Engineering controls are physical changes to the workplace that isolate workers from hazards, and are considered the most important set of methods for controlling the health and safety hazards of nanomaterials ...
A fume hood is an engineering control using local exhaust ventilation combined with an enclosure. A sticky mat in a nanomaterials production facility. Ideally, other engineering controls should lessen the amount of dust collecting on the floor and being tracked onto the sticky mat, unlike this example. [5]
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [ a ] It is a widely accepted system promoted by numerous safety organizations.
