I bcliovo that thie approach, rather thnr. by ororr- tlon, vlll point up more clearly the recponuibilitles of the industrial hygienist. The follouln3 is a partial Hot: 1.

Metallizing operationc, lccd burning, oand bleating and pipe recon ditioning -- all prccent potential lrductrial hygiene problems. Tho problem of inductric.1 dermatitic io like the poor -- always with us.

EMO 0312 0 i -3- Erposuro tc carcinogens, known and ouspoctod, dips heavily intr the time arxJ energy of the industrial hygienist. All cf ur. are fan! linr with the problem associated with was praaaing. The control of thio problem., however, may not be auffieiently complete aa atatlatical evidence in Bound ing that the incidence of aycteoic manifestation among thio group cf cxf ic., sos in out of line with that for the general refinery population end the population at large. The control prograa muct be continually observed end reviewed to incuro that maziEUE worker protection io provided. Animal experimentation hoc indicated that certain heavy fractions fran catalytic cracking are potentially carcinogenic to man, ae are the Its from cteam cracking and thermal reforming. Tho control programs for thee: materials have boon discussed in detail and need not be reviewed at thio time except to indicato that they represent a significant effort on the j-rt of industrial hygieno porsonnol,' pact and procent, and there lo every reason to believe that oven greater industrial hygiene effort will bo required before all groups ccnccmod with the problem arc nurc that a oaticfacto.-y control program hao toon evolved, inaugurated, and io running smoothly. Excocsive heat exposures cannot bo oolved for p.lcnt personnel ac easily ac fer office cnployect vhero the latter can be cent home in the middle of the afternoon if it gets too hot. Such expoourcE, directly acoeciated with tho work, occur in such widely varied activities ob pipe bonding and furnace thermocouple servicing, certain boiler house o.ctlvltico, end working in conflnod areas where tho equipment has not cooled down entirely. Curing certain soaeon*, any physical labor of a strenuous typo, and especially if it la performed in direct sunlight, may represent an occunational exposure of no moan significance. EMO 03121 - 1* - A medical opinion has been cxproaocd in certain of tie refineries that hearing impairment is relatively caanon among certain groups c'f vcrksrc, ouch ao the boilermakers. However, high noiee levels aro encountered in other parte of the rofinery efl veil. Potentially undesirable noiee lo ve lx might be encountered in the vicinity of high-speed pumps, in comrrcoco;roems, in generator rooms of the penfar houses, to mention only e feu. Inadequate lliumiration la a problem that affacto clerical personrcl as much and ea often aa process workers. Satiafactory illumination must bo considered in closo conjunction ulth tho Job to bo performed and is u con-esite cf a number of itena -- the intenaity of the light/ its color/ contract, amount of glare, and angle of incidence. Potential difficulties arising from inadequate illumination mey bo encountered in any tree of the refinery but is most likely to arloc from clerical activitioa. Fortunately, the open type of construction employed in retrolcux: refining reducee tho number and vnrioty of gonornl ventilation problem with vhich tho industrial hygienist crurt contend. On tho other hand, there nit numerous lnotances vhere enclccurcs liavo been ccnoti-uctod for the shelter of men and/or equiprant,eri the ventilation of these cpacoc then be caror a problem. Pun? hounco frequently offer exposure? to hydrogen sulfide; com pressor houses may provide exposuros not only to hydrogen sulfide, but also to methyl chloride, eiacnla, or oemo other refrigerant. In many caeca local oxhnuot ventilation ir. required for spacin'operatio_ns. Each of ua ic familiar vith the cpray paint sooth end tho laboratory hood, but tho ncod for thio typo of vontilotion can bo dcaonstrrted for mctaLli2if^-operetions, permanent voiding locations, dogreaaers, and driers, calendars, and ducting machines In rubber manufacture. f0 03 12 2 - 5- As in the cose of illumination, each operation mint bo considered on an individual basic. If no ventilation is provided, then the coed for such control must bo demonotratod and asoistance provided to bo sure that the system vill be of the correct doclgn and of suitablo capacity. Ee:ciu.~o ventilation for hoaltfc protection io so poorly understood, every Industriei hygienint oust bo conversant with hoed and duct design, fan types, and the proper collector to tics for the specific contaminant. The capital out .Icy for a satisfactory vontilating system is for too large to porait unconcern ovor ila future performance by the irduntrinl hygionlct. Vibrating tcole are in use throughout the plants end their effect' are of Interest from an occupational standpoint. Those instruments nine.: from electrically driven star driUo, to Jackhammers and pavement breakers; r.ntl fram tho use of chipping chiceln,to riveting operations. Thoso noed to be acrutinited from the standpoint of frequency anti duration of use, tho number of cycles por minute, and foaturoo peculiar to tho activity that may have significant medical ic.pllcationn. Since the onog Incident r.t Donora, Pennsylvania, currently being investigated by the Industrial Hygiene Dlviricn, U.S. Public Health Service, the specter of atmospheric pollution has htunted the industrial hygionict. This individual i6 trained and experienced on the evaluation and control of atnosphoric contomlncntc within a plant and it 1b only a small stop, and a very logical one, for him to be called upon for similar functions related to tho discharge of ur.decirable contaminants into the atnosphore of a community. All cf tho Esso rcfincrioo nro located in urban areas, and it la not unlikely that tho vork load of the inlurtrisl hygienist will be augmented by boing cnllod upon in some degree to asr.iGt manage this fiold of onieavor. in EM003 12 3 * -6- With respect to oonitory facilities, it would bo deoirablr to b< assured that all governmental requirements arc met and exceeded and that any control program, aa in tho ccxo of the carcinogcna, will not bo in-jaded by the lack of lavatorleo end shevert. In cortain cf our eotablishncnlc, tho lack of suitable facilities, tboir location, or their physical condi tion, io a very real problem. On the other hand, thir condition la being steadily allovlatcd^ and tho nert few years should find tho cituntion much improved. . In addition to tho industrial hygiene problems end activities previously enumerated, thero aro others, real or alleged, that require invent!gation. lontordey wo hoard of tho cancor problem associated villi the manufacture of isopropyl alcohol at the Beyway Refinery. Thin problem, considered acuto by the local menagecent becauso of the employee roletlono eopoct, hao entailed a tremendous nacunt of effort and the oai io not in sight. Dovoloping incidonco figuroo for tho Chemical Iroducto area alcne utilized all available) poreoznol from tho Nodical Department of tho Jersey Company and our own for ocveral weeks, and incidence figuron for the alcohol plant are Just now bolng completed, Tho etiologic agent is not known but no offort in being aperod to identify it. Only after the problem hao been voll dofined will it bo possible to set up an intelligent control program. Tbs facto evolved at Bayvuy must then bo translated, insofar ae they arc comparable, into a program at Baton Rouge. ' _ Several studios of a similar typo may bo in ordor in other refin eries, inasmuch as otatccouto rolatlvo to tho incldoncco of certain medical entitioo have'oon made and ohould either be substantiated or disproved.

This survey pointed cutthrough the ropert that communicable dlsaaoas were cosily transmitted by various lnoects under the existing conditions in tho Refinery. Hie washing and eanitary facilitioo avnllablo to tho employees were reviewed. Reeaanandnticns for tho increase in the number of thooe fc.cilltiOB wore rondo and In many caooo the naodod chan goo or additions have been occured. This program hoe been wall underway alnco before the connec tion of tho Industrial Hygienist with the Compeny, but due to the bringing to light of many industrial hygiene problcmo which would dictate tho noed for the oxpanaion of the facilitioo, thin program has now rocchsd tho otc.tr> that the approval cf requested facilltieo from top mrna^cment lo aspurod if they are escentlal in tho codiral program. By tiro beginning cf the yosr 1950, the facilitioo which wore soon to have boon noodei will bo completed or under conntructlon. In a few locations where toxic matorialo were being handled end the nature of the work mac.o it nocesr.nry for the employees to got badly ootlod, hot water has. been added to tho present vnohing facilities. The precenco of toxic materialo vao brought to the attention of the Managsc-int to Justify the added expense of installing hot water.

This latter will oocn be undertaken by tho analytical laboratory.

More than 60 campion have been collected and chocked for mercury oo far. Thia study io continving. In several locations mercury vapor* have been found by atmospheric earnling. In aora of thcce locations vhore mercury io rogtOerly ueetl; a voekly check ia being nado tad a record kept by tbe oporatine peroonnel or the analytical laboratory at the request of tho dopartoratal cupcrvioor. Other heavy metals vhich have been loceted and vo knot' present enough enposure that they nhould bo etudied are zinc, chromate, cadmium, and to a Iccc-or degree, beryllium. Up to tbe present tine no quantitative values arc avail able on those materiala. Silica and asbectco are both extensively ucod in the Refinor;- by a limited number of employccc. To date the only quantitative study ve have made dealt vith the cempocition of contact cloy. The free silica content or' those clays has been dotormlncd by a carorul chemical analysis acriotcd by x-ray spoctogroph. It is felt that a otudy on the atmospheric concent;-atioi:s on silica and silicate dust accoclatcd vith rclinlr.c the furnaces is cf immediate importance. Silica bricks are commonly urod in lining tho furnaces U6ed in the Refinery. Even vhere eilicate bricks are uacd, it ie knovn that in high tomporaturos thcoo ailicateo deconpoco to form very dangerous forma of eilica, criotobnlite, end tridjmltc. The empoeure to nsbootoa under normal operating conditions in the Refinery ie not' oztencivc "but frequently it is nececeary fer an inculator to do work inside of a closed apace vith limited ventilation, making It roscUve that a high concentration of asbeatoc dust may be engendered.
