the mouth, nose and throat. Skin contact: transient mechanical
irritation. Eye contact: direct contact will cause mechanical
irritation. Ingestion: unlikely to oc cur.

effects of overexposure: many studies have been conducted to determine
the potential long term effects of fibrous glass inhalation. In man
epidemiology studies of workers employed for up to 40 years in
fibrous glass manufactu ring do not show any consistent evidence of
pulmonary diesease, eigther malignant or nonmalignant. Studies in
animals using the natural route exposure have not shown evidence of
a carcinogenic effect. artificial implantation of large quanities
of very fine glass fibers in the chest or abdominal cavities of
laboratory animals has caused cancer. See msds for details.

medical cond aggravated by exposure: any condition generally aggravated
by mechanical irritants in air or on skin.
