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 ...
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 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.
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 mechanical cage inside a dusty bag moving to beat off the built-up material Actuation of a rotating mechanical cage for dust removal on filter media. Although the principles of this method are basic, the rotating mechanical cage cleaning method is relatively new to the international market.
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 ...
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]
Dust collection is an online process for collecting any process-generated dust from the source point on a continuous basis. Dust collectors may be of single unit construction, or a collection of devices used to separate particulate matter from the process air. They are often used as an air pollution control device to maintain or improve air ...
