Glass Fiber From an Office Partition Through the Microscope

Glass Fiber from an Office Partition

This is glass fiber from a micro-vacuum sample of an office cubical divider. The sample include a number of prills from the cloth covering but when they were removed the dominant dust was this glass fiber from the partition core. People at these workstations were complaining of upper respiratory problems.

A common structure for a cubicle divider consists of a metal frame supporting a resin stiffened glass fiber panel. The glass fiber panel is then covered with a thin loose glass fiber blanket and an outer layer of cloth. Glass fiber from the cubicle divider is heavily coated with heavily filled yellow or orange phenolic resin. The deterioration of the glass fiber panel is typically due to the panel's use as a pincushion or to other forms of mechanical damage.
