Fibrous glass is the name for a manufactured
fiber in which the fiber-forming substance is glass. Glasses
are a class of materials made from silicon dioxide with oxi des of various metals and other elements, which solidify
from the molten state without crystallization. Typically,
glass filaments >3 μm in diameter or glass “wool” with
diameters down to 0.05 μm & length >1 μm.A fiber is
considered to be a particle with a length-to-diameter ratio
of 3:1 or greater. The volume of small diameter fiber pro duction has not been determined. Fibers with diameters less
than 1 μm are estimated to comprise less than 1% of the
fibrous glass market. Specific gravity (H2O:1) = 2.5.
Hazard identification (based on NFPA-704 M Rating
System): Health 1, flammability 0, reactivity 0. Insoluble in
water. | [CAS DataBase Reference]

water. | [Potential Exposure]
The major uses of fibrous glass are in
thermal, electrical, and acoustical insulation; weatherproof ing, plastic reinforcement; filtration media; and in structural
and textile materials. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. If this chemical has been inhaled,
remove from exposure, and move to fresh air. | [Waste Disposal]
Fibrous glass waste and scrap
should be collected and disposed of in a manner which will
minimize its dispersal into the atmosphere. Emphasis
should be placed on covering waste containers; proper stor age of materials; and collection of fibrous glass dust.
Clean-up of fibrous glass dust should be performed using vacuum cleaners or wet cleaning methods. Dry sweeping
should not be performed. |
