Asbestos bulk sampling procedure.
Am Ind Hyg Assoc J 1985 Feb; 46:B8,B10
A technique for removing a portion of material for analysis which will leave the original piece of material as little damaged as possible was described. The need for such a technique arose out of concern for individuals who were collecting samples of material which they thought might be asbestos (1332214) from buildings and sending them to laboratories for further study. Some of these samples had obviously been taken with much disruption of the original substance and probable danger to the sample taker due to the large number of fibers introduced into the air. The sampling technique suggested calls for the use of any cylindrical device that is thin walled, has a sharpened edge, and a diameter of 1/4 inch or so to remove a core sample. Steps to use in collecting a sample included wetting the surface to be sampled, using a containment device or a respirator, obtaining a representative sample, labeling the sample, cleanup and repairing damage, sample shipment, and laboratory preparation. A minimum of three samples was suggested for a homogeneous material less than 1000 square feet in area, with seven samples for areas over 5000 square feet.
