To identify employees potentially exposed to materials or physical hazards which could result in chronic occupational disease, i.e., henzene, lead, ionizing radiation. This information is of assistance to the plant physician in deter mining the type of tests to he performed on the employee at the time of his periodic examination. 2. To identify employees working with or potentially exposed to materials which could result in immediate or sudden symptoms and disability, i.e., aniline, metal carbonyls, tetra ethyl lead, etc. Eds information is of assistance to the plant physician in arriving at a diagnosis of illness in an employee who appears in, or is brought into the Medical Department in obvious distress. In setting up the materials and operations list, it may be simpler in some cases to list occupations. For instance, a sandblaster, or a leadbumer, is by occupation, potentially exposed to silica ead lead, respectively. Welders and burners are listed by occupation because they are potentially exposed to many hazardous metals era toxic gases.'- In general, these lists of employees are relatively stable end keeping current lists is not a major task. .'hero hazards such as noise, benzene, mercury, etc. ere involved, it becomes more difficult to maintain accurate lists of exposed employees since widely different employee groups may be potentially exposed, i.e., process employees, laboratory workers or several mechanical-crafts. Loth lists, of materials and occupations mast be kept reasonably up-to-date if they are to serve their purpose. Following a survey of all process units, mechanical operations and other opera tions (printing office, laboratories, etc.) a list of potentially harmful materials or physical hazards is compiled. All employees who- are potentially exposed to these materials or operations are listed under each material. The evaluation of "potential exposure' should be made by the Industrial Hygienist or other qualified person. use L_tsr. Rouge material lists are abbreviated four letter codes having sons actual or p_snetic resemblance to the occupation or potentially toxic material, i.e., IDIR for Leadbumer and HOIS for noise. These codes are keypunched on ISM cards used for other medical end personnel data. -ihse-ts are obtained for the entire toxic code list. For easier revision, these skse;. may be run by (l) toxic material or hazard, or by (2) department or craft, or (l; by ascending employee number, or (b) by alphabetical listing by name. These lists facilitate the revision of the lists which, as previously mentioned should be dome periodically.. 1h, EM003526 ASBS BENZ BUWE CARB DUST HBCCO IPOH ^ LDBR MECL MERC NO IS PNTR RADI SHAL SNBL TELL TIMM WAXX Toxic Exposure List 1966 Asbestos Benzene Burner Welder Carbonyls-Ni and Co Physiologically inert High Boiling Catalytically Cracked Oils Isopropyl Alconol Mfg.

W. Hammond P. 0. Box 2180 Houston, Texas Dear Mr. Hammond: I am sending you a few items which will indicate how our Toxic Exposure Lists are maintained. 1. List of Potentially Hazardous Materials. A four letter code, usually phonetically determined is used. All materials having significance from either chronic poisoning (EE\Z) or capable of causing sudden illness (ANLN - Amilir.e) are listed. 2. Personnel Inventory. The entry code tells the keypunch people wether to add (302) or delete (303) the employee numbers on the list. The wavey lines are used to avoid repetition in filling out the form. 3. Print Out. This list can be printed out by several ways: a. By toxic exposure b. By ascending employee number c. By department Periodically this list is revised. Those to be deleted are scratched through. Those to be retained are marked "ok". New exposures are listed separately. Personnel inventory forms are made up showing changes only. Please let me know if you need further information.
