Asbestos (1332214) exposure to workers handling burlap bags was used to wrap rose bushes (SIC-0181) was investigated. A commercially produced burlap bag was shaken for 60 seconds in a small, unventilated room, and was then used to wrap the base of a rose bush. Asbestos concentrations were measured in the breathing zone of the worker performing the test, and at room heights of 6, 33 and 60 inches at a distance of 2 feet from the worker. The sampling period lasted for 4 minutes. The average breathing zone asbestos concentration was 490 fibers greater than 5 microns in length per milliliter (f/ml). At 6, 33 and 60 inches, asbestos concentrations were 500, 350 and 470f/ml, respectively. The author recommends field surveys to determine actual worker exposure to asbestos.
