Health Hazards in th2 Foundry
By CAREY P. McCORD, M.D.
Medical Director, The Industrial Health Conservancy Laboratories, Cincinnati, O hio
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 alt foundries. 2. Excessive heat means high loss of valuable chlorides from the body and calls (or replacement. The use of salinized drinking water is now better estiririished 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--notably 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.

7. 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 oi 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 ties, 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 Wealth 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.
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 matters--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?
Many foundry operators are faced with suits or other form of claims that undoubt edly at related to previous employment in other foundries or other dusty trades. 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 previous foundry exposure is more biamable in the causation of silicosis than two years of similar exposure in present employment. Yet the present employer is likely to find himself saddled with full responsibility.
Lately I have had opportunity to examiqe well m&de film negatives of applicants for work, without admitted previous exposure in industry. These persons were found to live and drive on dusty country road* made of flint Approximately 50 per cent of these young adults presented sufficient involvement in their films to be rated as "suspicious" in relation to pneumoconiosis. Given a few months exposure in a foundry 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 x-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 x-ray evidences of any degree of involvement resulting from the action of dusts or the presence of other pulmonary pathology in well estab lished degree, should be denied employment in any dusty exposure. Expensive as x-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-prone juries.

2. What hall be done with the worker* known to posse* dusty lungs? In late months many employers in dusty trades have procured routine x-ray exami nation* of all employees. Out of every hundred undisabled men, properly examined, a fair percentage is likely to present some degree of clear-cut pneumoconiosis. What is to he 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 fair-minded opinions as to appropriate ac tion for this very time may be epitomized as follows: Seek to eliminate further exposure to the dust hazard. Do not apprize any undis abled workman of his condition. Make repeated x-ray examinations at about six months intervals. If advancement of the condition appears, then take action suited to 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 ne^ro at this time is rated as a greater risk in the foundry than whites 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 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 pitfalls, 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 non-dusty departments; in the detection of unsuspected dusty work points. i. In litigation what medical defense may be involved?
Without presuming any qualification* 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 trial. 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 -of 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) The'denial of disability or prospective disability: A large number of work men 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 year* such as 15, 25 or 40. Since the medical pro-

fession has professed scant knowledge of these diseases during these periods, it is unreasonable to believe that the industrialists could have possessed more. Inevitably it follow that operators of dusty industries may not be presumed to have possessed earlier and greater information of these occupational diseases than physicians, indus trial hygienists, state health departments, state factory inspectors, and other agencies devoted to health conservation. No industrialist may be charged with neglect for failure to supply protection against an insidious disease unknown or little known to the medical profession. Even at this time the average physician possesses the most meager information as to these conditions.
(d ) The origin of the dusty lung disease in previous employment: Manifesting it is unjust that a few weeks of employment in some one foundry should be held re sponsible for a well established dusty lung disease when antedating this employment, there have been years of exposure to similar work in other plants..
(o) The origin of the dusty lung disease from causes other than industrial em ployment: In some localities over the country it seems probable that sufficient dust may arise from roads, farm work, etc., to induce characteristic involvement of the , lungs.
(f) The actual quantity of dust present in an industry is below any reasonable threshold of probable production of damage: The mere fact that an industry or de partment is classified as a dusty operation is not in itself proof of the possibility of development of pneumoconiosis. The nature and extent of protective devices may fully exculpate the plant as a practical hazard. Dust count methods have certain un deniable limitations, but this form of testing along with tests of the efficacy of ven tilating apparatus may be utilized on occasion wholly to eliminate any justification for contention that the air dustiness prevails.
(g) Diseases other than pneumoconiosis fully may account for abnormal stale in the lungs, or other chest contents: At least ten other diseases may so stimulate pneu moconiosis as to permit confusion and error. Among others are fungus diseases, tuberculosis, especially disseminated tuberculosis, cancer, syphilis, pleurisy with calci fications, certain types of unresolved pneumonia. In addition, claims are known to have arisen alleging pneumoconiosis when in fact the pathology centered about such unrelated conditions as aneurysm, mediastinal tumor, anaphylactic asthma, valvular
heart disease, etc. (h) Silica is not a poison: In some states claims.at law must be based upon acts
applicable only to poisonous substances. W hat constitutes a poison is a matter of definition. At the present time, the best thought as to the action of silica within the lungs is unfavorable to acceptation of it as a poison. Primarily, silica action is physical rather than chemical.
(k) Pneumoconiosis does not constitute an accidental injury: In some instances it has been contended that dusty lung states are accidental injuries. Such specious arguments ordinarily are put forth ;.n effort to obtain compensation in political states where no provisions are made for occupational diseases. To the contrary, every valid concept prompts a recognition of the pneumoconiosis and occupational diseases.
These several defense items are of course not set out as having any element of the panacea. However, on occasion some one or more may play a helpful phrt in de feating some of the cases now pending, richly deserving defeat.
