The aspirator creates a vacuum that draws wood dust up through the holes of the sanding pad. An innovative dust control system has been developed that uses additional exhaust and a slottedanding pad. [3] LEV for orbital sanders [3] Dust control plenum for orbital sander [3] A new dust control plenum has been designed for orbital sanders.
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.
Dust in homes is composed of about 20–50% dead skin cells. [2] The rest, and in offices and other built environments, is composed of small amounts of plant pollen, human hairs, animal fur, textile fibers, paper fibers, minerals from outdoor soil, burnt meteorite particles, and many other materials which may be found in the local environment.

The use of podiatry drills, in the absence of engineering controls and personal protective equipment, is an occupational hazard to the healthcare provider.Nail dust collected during foot care procedures performed in office settings has been found to contain keratin, keratin hydrolysates, microbial debris, and viable fungal elements, including dermatophytes (most commonly Trichophyton rubrum ...
Coal ash contains many toxic substances that may affect human health, if people are exposed to them above a certain concentration in the form of particulate matter.So it is necessary to avoid situations in which employees working in coal-fired power plants or public members living close to coal ash landfills will be exposed to high coal ash dust concentrations.

One of the biggest contributing factors that the effect atmospheric dust has on humans is health, more specifically respiratory health. [3] Barbados and Trinidad have seen a rise in asthma in their population and one of the speculated causes is an influx of dust being carried over the Atlantic from the Sahara desert.
All types of asbestos fibers are known to cause serious health hazards in humans. [1] [2 ... agreed to sponsor research on the health effects of asbestos dust, but ...
An epidemiological study conducted by the National Cancer Institute reported that higher levels of chlordane in dust on the floors of homes were associated with higher rates of non-Hodgkin lymphoma in occupants. [25] Breathing chlordane in indoor air is the main route of exposure for these levels in human tissues.
