DKM/20 INTRODUCTION TO THE ORC ASBESTOS DATA COLLECTION PROJECT GOALS To build a data base on the levels of airborne asbestos fibers generated during the completion of a variety of routine jobs in the chemical, petrochemical, telecommunications and utility industries. INTENDED USE This data base is intended to allow the participating companies to meet the requirements of the Occupational Safety and Health Administration for "objective data". The source of the data will be kept confidential with only ORC retaining knowledge of it. ORC needs to be able to contact the submitting company should questions about the data arise. METHODS The intent is to monitor a variety of separate jobs, and to establish a TWA exposure for each job. This would be done in the chemical, petrochemical, telecommunications and utilities industries. For the purposes of this study we are less concerned with the overall exposure of the individual (8 hour TWA) than we are with the actual fiber concentrations generated by each specific task. THE BENEFITS If, as expected the data shows exposures to be consistently below the action level of 0.1 f/cc, this "objective data" should provide participants with a valid data base upon which to defend a decision not to perform "initial monitoring" each time a small asbestos removal job, or other small job involving asbestos, is started so long as standard techniques are used. In the telecommunications industry this data base can help document the kinds of exposures that can be expected in routine telephone and cable installation jobs where it is known that asbestos is present. Protective measures appropriate to the known hazard can then be put in place to meet the requirements of the OSHA standard, and adequately protect workers. In those industries where it is not always known whether or not asbestos is present, the monitoring of a large number of randomly selected, short duration, low exposure jobs across the country, should give a solid indication of the probability, on any particular like job, of encountering levels of asbestos at or above the 0.1 fibers per cubic centimeter of air, the action level in OSHA's asbestos standard.

D C 3000-1 -2- RIGH CREDIBILITY NECESSARY The requirements that OSHA is establishing for the collection of this "historical objective data" are strict. Therefore, for the data base to be credible and thus usable, all data must be collected in strict accordance with the rules of the study. If we accurately collect monitoring data relating to levels of airborne asbestos fibers generated during certain operations, it can be used with confidence to meet our obligations under the OSHA Asbestos Standards. If we do not make every effort to be as accurate as possible in this study, we will be wasting both our money and our time. REQUIREMENTS OF THE' STUDY The following are the general requirements that all participants in the study have been asked to meet in order to insure the smooth functioning and high quality of the study: 1. This study will require that participating companies monitor a significant number (to be determined internally) of their employees engaged in activities where they may potentially be exposed to airborne asbestos fibers. 2. Documentation information will be collected for each operation monitored, recorded on the ORC forms and send to ORC in a timely fashion. 3. The data base development, data entry, and analysis of results will be done by a contractor, selected by ORC and approved by the Task Force, at a price agreed upon by the Task Force. 5. The cost of the study will be divided equally among those participating in the study. 6. Each participating company will receive a block of numbers that are reserved for its use. These numbers will be used sequen tially to identify the sampling data sheets. 7. Each sheet will be the data for one person and one task performed. 8. For each job an actual TWA and 8 hour TWA will be calculated. 9. All participants will follow the relevant requirements of the OSHA Construction Asbestos Standard (1926) or the General Industry Asbestos Standard, 1910.1001. OrU.ini/.Hinn Kcsumt's Counselors. Ini. 1331 PennMlvjm.i Avenue. \ AN VNjvhinpnn. n c :oooj -3- 10. All participants agree that sampling data will be for those doing "hands-on" work, not supervisors or observers. 11. All participants agree that all analytical work done for the purposes of this study will be performed by laboratories certified under the existing Proficiency Analytical Testing (PAT), or the American Industrial Hygiene Association (AIHA) Asbestos Accreditation Program. 12. Where possible, the data collection forms should be filled out by industrial hygienists using their organizations monitoring data forms. 13. The sampling data forms will be signed by the person filling them out. The company name and address and a phone number for the person signing the sheet should be included. After data entry this information will be removed from sheets. 14. Where reasonable, a certain amount of third party, (contrac tor/consultant) monitoring should done as part of the study and identified as such on the data sheet. 15. Each participating company should submit once, a separate company cover sheet to OHC. This sheet will include overall information about the percent of the potentially exposed employee population that was monitored, the total number of employees monitored, and total number of employees in the corporation. 16. The company cover sheet should discuss how jobs enter the system, and how the particular job site and individual(s) who do. the work are chosen. This needs to be done to document the method used internally to obtain a representative selection of samples. 17. Detailed data from this study will be available only to those organizations that participated in the study. 18. Companies not having participated in the study initially, but wishing to have access to detailed data from the study after it is completed, must agree to do a certain minimum amount of sampling using the agreed upon task force protocol and data collection forms, the results to be entered into the data base. 19. Once the information on the sampling data sheets has been entered into the data base, a summary of the compiled data will be provided to participating companies. Participants will have access to the original data, except for company names, through ORC. 20. The final results of the study will be written up and, upon review and majority approval of the task force, they will be submitted for publication to the AIHA Journal.

DC. 20004 -4- This data is to be collected with all participants using the same sampling and analytical techniques, and the data recorded on the same form. This information will form the data base of "objective data", documenting the levels of airborne asbestos fibers generated in a variety of jobs, across 4 large industrial classifications, and many individual corporations. This monitoring data is to be collected with a high degree of accuracy, and thoroughly documented. It is intended that this study be highly credible and able to withstand close examination and criticism. Many of the jobs that this project will examine are similar across a variety of industries. For instance, removing asbestos insulation from around a valve before working on it. This job, if done in accordance with accepted, good industrial hygiene and safety practices, will be performed similarly in the chemical, petrochemical, or utility industries. With similar jobs and procedures, one would expect that actual levels of airborne asbestos fibers generated would also be similar across different industries; the study may tell us if this assumption is correct. Sampling Data Sheets Two sets of sampling data sheets will be used; one intended for use in "small scale" work as defined by OSHA, and the other for primary removal, demolition and renovation. Small scale work would include a variety of jobs in the chemical, petrochemical, telecommunications and utilities industries where the removal of asbestos was incidental to the accomplishment of the job. Large scale jobs would include those where asbestos is being removed from buildings, where asbestos containing pipe insulation is be removed and will be replaced with other insulation, and other operations where the removal of asbestos is the main purpose of the job. Each set of sampling data sheets will have two pages of questions designed to collect background data, and one air sampling data sheet to record the actual monitoring data.
