The speaker said in part Over and over again it seems necessary to restate in many guises such well established foundry fundamentals as the following 1. Excessive heat is a hazard common to all foundries 2. Excessive heat means high loss of valuable chlorides from the body and calls for replacement The use of salinized drinking water is now better established as desirable than ever before More rather than less salt is advocated for the normal foundry worker exposed to high temperatures 3. Molten metal emits chemical rays at times harmful to the eyes Goggles fitted with glass barring these rays prove their worth to the workmen in many plants 4. Metal fume fever fortunately is fleeting in its known effects but no less is real It is more often found where zinc enters the metal mix 5. Sudden and extreme variations in temperature may be the lot of foundry workers so in winter The body makes adjustments to these quick changes with admirable facility _ No less these burdens are conducive to respiratory diseases including pneumonia Pneumonia reaches highest frequency among foundry men 6. Lead poisoning is far from rare in the foundry il Corp.

Carbon monoxide may be found in harmful quantities 8. Antimony nickel cadmium manganese phosphorus arsenic and sulphur may on occasion find their way into the crucible and thus make possible the development of ill health traceable to such causes 9. In core making many binders have led to skin diseases 10. If metal grinding polishing and buffing constitute a part of the foundry's activi- tier a long list of additional hazards may be cited ranging from the action of chrome polishig materials to tenovitis from the drag of the buffing wheel 11. Last but foremost is the hazard of dust At the present moment concern over health hazards in the foundry may be divided in the ratio of 99 per cent for dusty lung diseases and 1 per cent for all others combined While this disproportion may not be warranted it appears desirable that I devote the major portion of my comments to selected items related to dusts and the diseases produced by dusts Confronted with any new and outstanding hazard in industry the tendency is to - exaggerate the requirements for control This notably was true when benzol first came into wide industrial application Now the conditions under which benzol may with safety be used are so well delineated that where these conditions are provided benzol poisoning is unknown A similar course is predictable for the silica hazard in foundries *, . so As the major problems connected with dusty lung diseases and their causations be- come harnessed by the specialist opportunity is provided for the consideration of many secondary aspects of dust and dusty lung diseases I propose now to comment on five of these slightly less significant important in my opinion to the employment manager the safety engineer and the plant physician 1. How shall the foundry operator protect himself against cases of dusty lung dis- eases originating in other plants that Many foundry operators are faced with suits or other form of claims undoubt- mF edly are related to previous employment in other foundries or other dusty trades NR Since silicosis may require and usually does require many years for its development to the point of disability it naturally follows by way of example that 16 years of . a previous foundry exposure is more blamable in the causation of silicosis than two me years of similar exposure in present employment to find himself saddled with full responsibility Yet the present employer is likely a tn Lately I have had opportunity to examine well m^defilm negatives of applicants for work without admitted previous exposure in industry These persons were found to live and drive on dusty country roads made of flint Approximately 50 per cent of these young adults presented sufficient involvement in their films to be rated as a suspicious in relation to pneumoconiosis Given a few months exposure in a foundry at anyone might hold himself eligible for claims against his employer alleging dusty lung disease The answer to the problem is definite Every prospective employee for any dusty portion of a foundry should be rayed by a competent maker and interpreter of chest films For the good of the prospective workman and for the good of the operator any applicant exhibiting any ray evidences of any degree of involvement resulting from the action of dusts or the presence of other pulmonary pathology in well established degree should be denied employment in any dusty exposure Expensive as rays may be they are likely to prove one of the most economic steps that may be taken in these days of wholesale litigation synthetic testimony unskilled physicians and plaintiff juries 322 Twenty Congress Safety Council 2. What shall be done with the workers known to possess dusty lungs In late months many employers in dusty trades have procured routine ray examinations of all employees Out of every hundred undisabled men properly examined a fair percentage is likely to present some degree of clear pneumoconiosis What is to be done with such men Many are not disabled Some are outstandingly hale and hearty Shall they be told of their state Many are likely to develop mental quirks and neuroses Some will take an unfair advantage of the employer through + claims A small consensus of mature and minded opinions as to appropriate ac- tion for this very time may be epitomized as follows pe take action Seek to eliminate further exposure to the dust hazard Do not apprize any undis- abled workman of his condition Make repeated ray examinations at about six months intervals If advancement of the condition appears then suited to Te the individual case Otherwise keep these men at some work 3. Are negroes more susceptible to dusty lung diseases than whites I know of no large series of cases arising under identical conditions in this country among whites and negroes that prove the negro to be more readily involved by dusty lung diseases The negro is more susceptible to tuberculosis than his white fellow workman His housing is likely to be on a lower plane His exposure to tuberculosis is prone to be greater than in the case of the average white man On account of this background the negro at this time is rated as a greater risk in the foundry than whites ee mae under conditions of equal exposure 4. How necessary are dust counts in detecting hazardous work points in a plant The dust counter has established itself as the best available yardstick for the deter- ee mination of different quantities of dust in the atmosphere Like so many instruments in its class the dust sampler and counter has been glorified far beyond its real merits Opportunities for errors are legion Legal standards based on present dust counting methods are utterly futile Notwithstanding many sitfalls however the dust counter is a most valuable instrument It finds its greatest usefulness in discriminating between much dust and little dust improving the efficacy of preventive measures and devices in the determination of the carriage of fine dust into dusty departments in the detection of unsuspected dusty work points 3. In litigation what medical defense may be involved Without presuming any qualifications in the domain of law the plant physician the safety engineer or the employment manager may be called upon to furnish attorneys all possible information in preparation for trials Below I am listing a number of items that are in prospective use or have been used in various instances a Denial of the existence of dusty lung disease Recently in the examination of a sample of 202 films men exposed and unexposed to dust one was singled out as exceptionally free of even usual amounts of fibrosis This film was examined as an unknown as were all others Later it was pointed out that the workman from whom this film was made was a litigant demanding a large sum of money on account of an alleged silicosis Similarly about four out of every five litigants alleging dusty lung disease are in fact free of such diseases The claims are spurious and may be proved so by appropriate examinations carried out by qualified investigators b denial of disability or prospective disability A large number of workmen whose lungs show some signs of dusty action are not incapacitated and no proof exists that real disability is an early prospect c The denial of neglect Many of the true cases of dusty lung disease have been developing over long periods of years such as 15 25 or 40.
