AIR QUALITY SERVICES, INC. 4527 Clairton Boulevard Pittsburgh, PA 15236 (412) 881-5630 A TEST TO DEMONSTRATE THE RELEASE OF ASBESTOS FIBERS FROM H.K. PORTER ASBESTOS ROPE FOR RANDALL A. BONO ATTORNEY AT LAW 65 EAST FERGUSON STREET WOOD RIVER, ILLINOIS 62095 BY JOHN O. FROHLIGER, Ph.D. FEBRUARY 1988 AIR QUALITY SERVICES, INC. INTRODUCTION Air Quality Services, Inc. was requested to determine the airborne asbestos fiber release that could occur from the cutting of Asbestos Rope manufactured by H. K. Porter Company. VIDEO TAPING OF THE PROCEDURE The test was video taped. CONSTRUCTION OF TEST CHAMBER The test procedure had to be designed to protect the environment from contamination with asbestos fibers. A glove bag obtained from the I2R Company was used to prevent asbestos fibers from being released into the environment. The glove bag was placed on a table. A light weight frame was constructed of dowel rods and connectors made of wood to support the glove bag and provide an. adequate work area. The necessary cleaning materials, amended water and wiping cloths were placed in the glove bag before the test. A sampling pump and a 25 millimeter filter for collecting asbestos fibers were placed in the bag. The filter was located to approximate the location of the face of.the operator. BACKGROUND ASBESTOS LEVELS In order to determine the background of the glove bag, a background air sample was collected in one glove bag. A battery operated pump, operating at 5 liters per minute, was operated in the closed glove bag for two hours. The background level in the unused glove bag is less than 0.001 fib/cc (fibers per cubic centimeter). CHAMBER TEST ASBESTOS ROPE BONO 1 FEBRUARY 13, 1988 685 S-131 AIR QUALITY SERVICES, INC. TEST PROCEDURE The operator was equipped with a half mask respirator equipped with filter cartridges approved for asbestos protection. The battery operated pump used for sampling during the test was calibrated at 3.6 liters per minute. The air sampling pump was turned on, the start time noted and the asbestos rope sample was severed. The severing of the rope required less then five minutes. The glove bag was left sealed and the asbestos sampling continued for a total sampling time of one hour. The analysis of the asbestos fibers was done according to the OSHA regulations, 1910.1001 Appendix A. procedure. Air Quality Services, Inc. participates in the Asbestos Proficiency Analytical Testing Program (PAT) developed by NIOSH and operated by the AIHA. Air Quality Services laboratory is rated "proficient" in the quantification of asbestos fibers by Phase Contrast Microscopy. RESULTS The results of the airborne fiber release during severing an asbestos rope is presented in Table I. The current OSHA Standard of 0.2 fibers per cc was exceeded by 1265 percent. John O.
