What Is Fibrous Particulate?

Fibrous particulate are small, slender bits of airborne matter that are typically inorganic. Though not necessarily considered hazardous, fibrous particulate is comprised of individual components that may pose health risks and concerns. Attempts to identify individual components of airborne fibrous particulate can be quite difficult, and may require microscopy, x-ray diffraction or other electrochemical methods.

Sources
- Fibrous particulate can come from many sources, which include clothing, floor textiles, building materials and paper products. Fibrous particulate may be too small to notice with the naked eye, and are often introduced into the air due to friction applied to these materials. Improperly cleaned or maintained ventilation may increase the distribution of fibrous particulates.
Measuring Fibrous Particulate
- The size of individual components of fibrous particulate is measured in microns, and may vary from 1 to 100 microns -- almost invisibly small to the human eye. In most everyday applications, particle counters are usually used to gauge the saturation of air with particulates using airflow.
Getting Rid of Fibrous Particulate
- Though it is almost impossible to eradicate fibrous particulate matter in the air entirely, special ventilation systems, such as high-efficiency particulate air (HEPA) filters, have been devised, which can greatly reduce their presence. These systems are used mostly in sensitive environments, which must be kept as sterile as possible, such as some hospital, laboratory or manufacturing facilities.
Potential Dangers
- Fibrous particulate can irritate the eyes, mouth and nose, and can be a concern in sterile environments. Though not itself considered hazardous, some materials that may comprise fibrous particulate, such as asbestos and silica, are potential carcinogens and may lead to other health concerns such as asbestosis and mesothelioma.
