Fiberglass is a man-made material used in many products in homes and workplaces. It is found in insulation, furnace filters, appliances, cars, airplanes and roofing materials.

Contact with fiberglass may irritate the skin, eyes, nose, and throat. High levels of exposure to airborne fiberglass may aggravate asthma or bronchitis. There are no specific medical tests to show whether you have been exposed to fiberglass.


You may be exposed to fiberglass during construction or renovations, or whenever existing insulation is disturbed. Exposure occurs by skin or eye contact, or by breathing in fibers that have become airborne.

Once fiberglass is installed in buildings, you will probably not be exposed unless it is disturbed.
