Travelers Rest Machine Shop
Asbestos Air Sampling ** W.'.>.Pr
.itejw
' .A -V'
There were "no visible fibers" detected in any of the three air samples taken in the machine shop at Travelers Rest.
The bulk sampler analysis revealed chrysotite asbestos fibers to be well distributed throughout the spray-coated wall materials. >'V ~
Since the wall coating material is flaking in most locations, I still believe there should be cause for concern.
