There is no evidence that fiberglass causes cancer in people. Animal studies have shown an increased risk of cancer when fiberglass fibers were implanted in the lung tissue of rats, but these studies are controversial because of the manner in which the fibers were implanted. When working with fiberglass products, you should wear loose fitting, long-sleeved clothing and gloves. This will prevent skin contact and irritation. Wearing goggles or safety glasses with side shields is recommended to protect the eyes.
Respiratory protection becomes necessary when large amounts of dust are generated.
Opening a window or a door to increase ventilation can reduce dust levels. Vacuuming should be done by first wetting the dust and fibers and then using a shop vacuum. Measures can be taken to reduce exposure after a person has come in contact with fiberglass. Eyes should be flushed and any area of exposed skin should be washed with soap and warm water to remove fibers. Clothing worn while working with fiberglass should be removed and washed separately from other clothing.
