Prevention of Pneumoconiosis
Pneumoconiosis almost always can be prevented. To reduce your risk, you can:

Limit work-related exposure to mineral dusts - Workers who routinely deal with mineral dusts always should use approved measures (protective equipment and clothing) to limit their exposure and keep from bringing mineral dust home on their clothing. If a mask or respirator is worn as a protection against dust, it must fit properly and be used according to the manufacturer's directions.

Prevent exposure to asbestos at home - Check your house, especially if you own an older house, for areas of exposed asbestos-containing insulation or deteriorating asbestos. The asbestos in these areas must be removed or safely sealed away (encapsulated) professionally.

Avoid cigarette smoking - Smoking worsens the harmful effects of pneumoconiosis. If you smoke, ask your doctor about proven ways to quit.
