• Description:
  Breathing zone samples were analyzed for asbestos (1332214) along Parks Creek Road in Shasta Trinity National Forest, Redding, California in July, 1984. The survey was requested by the staff engineer for the United States Department of Agriculture to determine whether Forest Service personnel were exposed to asbestos fibers when they traveled along Parks Creek Road. The road was resurfaced (SIC-1610) in 1983 with a serpentine aggregate material. Bulk quarry samples analyzed at the time of resurfacing contained 1 to 10 percent chrysotile-asbestos (12001295). Two of six current samples contained asbestos at concentrations of 0.17 and 0.18 fiber per cubic centimeter (f/cc), length greater than 5 micrometers (microm). The OSHA standard for asbestos fibers greater than 5microm in length is 10f/cc. The author notes that the measurements were made under worst case conditions, being made in the morning when no other vehicles were on the road except a watering truck. In view of the fact that chrysotile was found in the bulk quarry samples, he concludes that there is a potential health hazard for workers who drive along the road. Recommendations include periodic air monitoring and driving along the road with windows rolled up.
