WARREN PROPOSED INDUSTRIAL HYGIENE PROGRAM FOR SHOPS & SERVICES AREAS Ref: Letter from L. T. Freeland to W. P. Ledet et al, "Industrial Hygiene for Shops & Services", Nov. 7, 1977 In 1977 the "Alathon" Industrial Hygiene area coordinator was assigned the responsibility of organizing and implementing an industrial hygiene program for both the "Alathon" and the Shops & Services areas. However, due to shortage of manpower it was agreed to establish the "Alathon" area program in 1977 and the Shops & Services program in 1978 except for "crisis items". In November 1977, a preliminary program was developed by A. H. Nickolaus (see reference letter) to obtain some data to answer questions posed in the S&F audit of October 1977 and to obtain monitoring data on the more obvious potential industrial hygiene hazards. The data developed by the preliminary monitoring studies are summarized in.Table I. Using these data and recent discussions with the S&S supervisory personnel we have developed a comprehensive industrial hygiene program for the Shops & Services areas. Table II outlines the major components of this program. In developing this program we obtained data on chemical material lists, data sheet lists, trade chemical lists, trade chemical compositions and area tasks involving chemical exposures. These data are summarized in Tables III through VIII. Key information relating to these tables are given below: DUP 0814653 DU 009935 3. S. Smith 2 July 12, 1978 (1) Tables III & IV list the purchased chemicals and trade chemicals, respectively. The list in Table III will be incorporated in the plant computer listing. Material safety data sheets need to be developed for the industrial hygiene manual for some of these chemicals as noted. In Table IV we have asterisked those chemicals for which some information on their chemical composition is known. (2) Table V summarizes the trade chemical composition data. Obtaining data on the composition of these trade chemical and updating existing data will be an on-going part of the industrial hygiene program. (3) Table VI lists the types of potential industrial hygiene hazards which could exist in the S&S area. (4) Table VII presents a list of tasks involving potential chemical exposure in the S&S areas. The initial risk appraisal evaluations(IRA's) for these tasks have been rough drafted and are being circulated for comments. Twenty seven of the 52 IRA's recommend obtaining some monitoring data. Six of these IRA's have been selected as items for the high priority list shown in Table VIII. This list will be modified to reflect the recommendations of the approved IRA's. Industrial hygiene hazards in the Outside Services Areas were intentiionally excluded from this program by prior agreement. However, we recommend that the current program in this area be reviewed and reorganized into a supplemental centralized program similar to the balance of the S&S area. To implement this program it will be necessary to establish priorities within the program and with the current "Alathon" Industrial Hygiene program and to establish areas of responsibility for the program. Once we have agreed on the above items a realistic time schedule can then be developed for the S&S Industrial Hygiene Program.
