A video on cleaning dust from workers' clothing. Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in ...
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 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.
Wood dust is known to be a human carcinogen, based on sufficient evidence of carcinogenicity from studies in humans. It has been demonstrated through human epidemiologic studies that exposure to wood dust increases the occurrence of cancer of the nose (nasal cavities and paranasal sinuses).
During air stagnation events, it is recommended for children, elders, and people with pre-existing health conditions, to stay inside as much as possible and stay hydrated. [8] An example or air stagnation in Northern France, where a sheet of black, thick, and odorous smoke formed and stagnated for a few meters.
People who had dust pneumonia often died. [1] There are no official death rates published for the Great Plains in the 1930s. In 1935, dozens of people died in Kansas from dust pneumonia. [1] Red Cross volunteers made and distributed thousands of dust masks, although some farmers and other people in the affected areas refused to wear them. [1]
Smog is a serious problem in many cities and continues to harm human health. [30] [31] Ground-level ozone, sulfur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma.

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.
