Key points
- Fibrous glass is a synthetic fiber made from tiny particles of glass.
- Fibrous glass is used in many industries and workers may be harmed from exposure.
- NIOSH recommends that employers use the Hierarchy of Controls to prevent injuries.
Overview
Fibrous glass is a synthetic fiber made from tiny particles of glass. It can harm the eyes, skin, and the lungs. Workers may be harmed from exposure to fibrous glass. The level of exposure depends upon the dose, duration, and work being done.
Fibrous glass is used in many industries. It is used in insulation, roofing shingles, ceiling tiles, textile and fiberglass manufacturing, and weather proofing.
Populations impacted
Some examples of workers at risk of being exposed to fibrous glass include the following:
- Workers who install fiberglass installation
- Factory workers involved in boat manufacturing
- Service workers who clean and install HVAC ductwork
- Construction workers who demolish buildings
Best practices
If you work in an industry that uses fibrous glass, please read chemical labels and the accompanying Safety Data Sheets for hazard information. NIOSH recommends that employers use the Hierarchy of Controls to prevent injuries.
