NOTES AND NEWS SILICOSIS Rackete-rr lawyers and doctors have added to industrial hazards the liability of unwarranted financial losses, as though it were not bad enough to have the possibility of workmen contracting silicosis in spite of every possible warning ar.d precaution. Silicosis and all other lung troubles classified under the sore general term 'pneumoconiosis" have, no doubt, always afflicted those who were at all active in factories, in streets, cr on farms. Science and science methods have disclosed these lung troubles. An accumulation of data and case histories has made more evident the causes and results. With increasing facilities and the acquisition of authentic sceniincaJly exact observations there has been on the part of plan: managers a growing sense of responsi bility and the need for protective devices for their em ployees. As a reward for these humanitarian disclosures and efforts, the racketeering lawyers and doctors have seen the chance for making easy money. It behooves every ceramic manufacturer to prepare a defense agair.st silicosis damage suits. The plant must be as free fretn fine air floating dust as is possible and the -nen must be warned and provided with dust masks. But these precautions are not sufficient. The plant managers must be prepared to show medical and X-ray records. .is further evidence1 of the seriousness with which the scientists have studied the matter of silicosis the following one hundred and thirty-five references are given from a report by H. X. Pancoast and E. P. Pendergrass.' Con cerning there references the auebors make the following stater.cn t: The references we have been obliged to consult were very numerous. The literature during the past few years bos been replete with articles dealing with the various phases of dust inhalation. We art obliged to restrict our firt of references to those articles which present particular points of interest to the roentgenologist. We have been obliged to omit many of the references included in our previous presentations. References E. Arnocld Is anthracosis a disease entity? P'esse mid.. 37, 162-1-26 (1929). C. Baxjhasc.

CERAMIC SCHOOL NOTES TEW YORK STATE COLLEGE OF CERAMICS AT ALFRED UNIVERSITY Dedication Erercises (or the New Ceramic Building, at Alfred, New York, June 12, 1933 Introductory Remarks by Dean Major E. Holmes T should like to call attention to the background of these ation ceremonies which our friends have made pos- ------ for us to arrange for today. The New York State College of Ceramics, recently ele- -Ated ,to that status from the status of a school, is the only institution in New York aevoied to higner education in ceramic;. For the ru.-r-r.: year u; enrollment is 217. this figure representing a 40^ increase over that of the preceding year. There is a staff of twelve instructors, each a specialist in his line of work. The College is or ganized on the basis of three departments, that of General Technology and Engineering. Glass Technology, and Ce ramic Art. The courses of study embrace ail 6elds of the ceramic industries in their three essential aspects of tech nology. engineering, and art. The school now consists of three buildings including the new one to be dedicated to day, and affords 40,000 square feet of floor space devoted to lecture rooms and laboratories. New. up-to-date equipment worth 5-40,000 has been installed in this new building during the past year and SIS.000 worth will be installed in the coming year.

SAYERS Chief, Division of Industrial Hygiene, U. S. Public Health Service . While dusts exist everywhere in the at is difficult to .establish a comprehensive^ mosphere, it has been recognized for cen definition for toxic dusts. Solimann,' after turies that workers in certain dusty analysis of various definitions for poison, occupations are less healthy than those not felt that it is very difficult to give a definition so, .exposed. ^Tlte number of persons ex which will not be ambiguous in some cases, posed-^i dujty occupations comprises one but believed that the following covers most ol the largest industrial groups. The occu of the points which must be considered in pational diseases of workers in dusty at classing a substance as such: r: mospheres Iiave been found to be due to entrance of dust into the system by inhala tion. by ingestion, by direct absorption through the skin, by irritation of the skin, or by a combination of the foregoing. The suspensions of particulate matter in air have been broadly termed dusts, fumes, and smokes. Such a classification is neces sarily arbitrary, since'the line of demarca tion between them is not very sharp, and the chief differentiation is based on the size of the particles. Investigations by the Pub lic Health Service in dusty industries' re "A poison is any substance which, act ing directly through its inherent chemic properties, and by its ordinary action, is capable of destroying life, or of seriously endangering health, when it is applied to the bods', externally, or in moderate doses (to 50 Cm.) internally." .'some dusts are known to be poisonous, while others, in the concentrations usually cnrountcrcd, are comparatively harmless. However, it may be stated tiiat breatUinq dust in high concentration is not desirable. vealed (hat aljuut 70 per cent of the dust According to Fairhall, the damage arising particles examined were between I and 3 from the inhalation of toxic dust may be microns in size, only ahoitt 20 per cent were cither local or remote, and depends upon less than l microti, and the median size was whether the material is a protoplasmic poi 1J microns. Industrial dusts arc mainly less son. whether it is caustic in reaction, or than 10 microns in size. However, fibrous whether it is absorbed into the blood stream dusts in the air, such as asbestos, have beat and carried to other centers which arc in found to contain particles as large as 200- turn affected.' 400 mircons in the greatest diameter. It is now well established that exposure While, generally speaking, according to to certain kinds of dusts, sucii as those con Collis. dusts arc more injurious as their taining considerable quantities of free silica, chemical com|iosition differs from tliat of lias increased the morbidity and mortality the human body, or from the elements of rate from respiratory diseases; while me which the Imdy is normally composed,' it tallic dusts, such as lead and its compounds.

CAMPBELL STARR Assistant Safety Engineer, U. S. Department of Labor, Division of Labor Standards, Washington, D. C. Silirod* is strictly an occupational disease. Medical science has not reported silica dust as aflcctiu^any individuals except tliosc who, over relatively )oii pvriocK of. time, have worked in :m atmosphere where the air which they breathe contained excessive con centrations of free silica. The interest of the U. S. Department of Labor in a broad social and economic prob lem such as tliis lias its origin in the Organic Act, effective March 4, 1913, which created the Department. This act, amone other things, juices the Department of Labor'ihc duty "to foster, promote, and develop the welfare of the wage earners of the United States, to improve their working conditions, ami to advance their opportunities for profit able employment.4' With this in mind, and believing that through joint effort of all concerned, much could he clone to eliminate the harard, the Secretary of Labor called together in Wash- m s - y = *r -s ^ o o: 3 4'5&:i^i5. l=-f4=^ s| it-rIb^" IllUilPi Mil!

Accordingly, the cummiUccs of the silico sis conference were unanimous in presenting the following rccominetulatious:. Coverage for silicosis in the compensa tion acts of all States. This coverage should be compulsory. Because of competition between the same or similar industries in various Stales, the laws, rules, and regulations of the several States should be as uniform as practicable. Should Be Insured The employer *should insure litre obliga tion (or compensation either through sellinsurance subject to the posting of adc- quale funds, or with an authorized in surance institution. Insurance should not he denied any em ployer. provided the State authorities certi fy that he complies with the State require ments as' to proper safe working condi tions. and lias's the premiums involved. Workers having active pulmonary tufrcrciilusis ami silicosis should he removed from employment. Such workers should . tic granted suitable compensation payments and medical care. Workers disabled from silicosis (hut with no tuberculosis) should ultimately lie granted the same amount of compensa tion as those disabled liv accidental in jury. Two years i a reasonable minimum limitation period for tiling claims subse quent to the' dale of the last exposure. Further Activities of the Department of Labor In carrying out its duty as stated in the liasic law, the U. S. Department of Lalmr has conceived that there is immediate need ior the conversion of known facts in the medical anil engineering fields working toward prevention, and in the legal, insurance and regulatory phases hulking toward ade quate workmen's compensation, into a prac tical. readily understood program which will adequately take carer nf the silicosis prob lem. In its program of cooperation with the -IS States, the Department of Labor has in cluded a section covering silicosis and simi lar dust diseases. This breaks down into three main sub-headings: (1) Assistance in the preparation of reasonable and adequate codes, rules, and regulations prescribing methods of prevention; (2) assistance in the establishment of equitable standards of workmen's compensation for those em ployees disabled as a result of the disease; (a) a general educational program among State officials, factory inspectors, etc. so that they will be equipped with adequate knowledge concerning the disease, its method of prevention, and its proper treat ment under the workmen's compensation law . Follows Two Lines This application program, which is just now getting under wav has been commenced along two principal lines: (l) The compiling >>f practical information concerning actual dust control installations in typical silica hazardous plants, together with approxima tions as to co*t. nut only of installation, Imt also of maintenance of dust routrol equip ment in such plants; 12) a program of visual education supplementing the summary and full commiuev reports of the National Sili cosis Conference. It is contemplated lint in Uu- held such media a- film strips, lantern slides, posters, illustrated bulletins, etc. will lie utilized. Further, in eimncetion with the various exhibits of the department, shown at various large expositions, trade association meetings, lalmr and technical organization" meetings, etc., it is contemplated that much fai-ltial information will lie used, limiting toward ways ami means of correcting ihc hazard anil of establishing adequate standarils of workmen's compensation.

SYMES Vice President, Operations and Maintenance Department, Association of American Railroads, Washington, D. C. Set industry in tire world requires more diversified study and more exacting applica tion of safety principles than the steam rail road industry. Picture a quarter of a million miles of railroad line covering in a virtual network the vast expanse of the United States. Over this network arc operated a billion train miles annually. Vast yard and terminal operations arc necessary to make up the beginning of the journey of passengers and goods, and to break up at the end of that journey the 12 million trains that accumulate that billion miles. These trains carry 50ft million passengers and one billion tons of freight annually. It requires more than one million railroad employees to rim the trains, make them ready for road movement, su pervise and safeguard their movement ami maintain the equipment and rnadited, as well as perform the many other duties incidental to the production of railroad transportation. Safe!}4 has ip the past, is today, and always will lie the first principle in railroad opera tions. But it is within the past fifteen years that greatest advances have been made in railroad safety. During that period we have seen a complete remodeling and moderniza tion of railroad physical properties. Road beds have been strengthened: bridges, trestles and culverts rchuilt; tracks have been laid with heavier rail and with treated lies of greater service life and de pendability; grades and curves have been eliminated or reduced; signal systems have .been modernized and extended: other safety devices have been installed; hew and more powerful locomotives, embracing all modern safety devices, have been purchased; new cars, both freight and passenger, have been installed. This capital improvement program lias cost the railroads aliout eight billion dol lars since 1V2J. and a large part, if not all, of that huge sum had a beneficial effect, di rectly or indirectly, on the safety of opera tions. But the engineer's job is never done. As soon as new equipment, new rail, or other devices me utslaiied titc engineers go to work to develop more efficient and safer units. The railroads spend millions of dollars annually in research and lalmratory work experimenting with engineering improve ments. In all this work safety is of primary importance. An invention whirl,i might mean great economics to the railroads would not find its way to a single locomotive or car if its use in any way lessened the opportunity ior safe operation. Conversely, any improve ment, mechanical or otherwise, promoting safety of operation immediately commends itself to railroad officers and employees. The search for greater safety will continue so long as railroad transportation is used.

C. WHITE Assistant General Manager, Missouri Pacific S. R., St. Louis, Mo. Safety is an obligation of management. Without the constructive leadership and dayto-day urge from the executive and. operat ing heads, the movement would lapse into a perfumery activity. The safety movement is recognized by executive and operating officers as a medium for building up and maintaining that rela tionship, that fellowship, which broadens our views, enriches character, and brings the Golden Rule into practical application. Management recognizes tltat our economic system must-.enable mgs. to live on an. in creasingly high qSfanc. aft must enable them to fulfill their desires and satisfy their rea sonable wants, ana-give, them that feeling of security which is essential to happiness and efficiency. Haring made the decision that safety is an executive problem anti rcs|onsibility--that accidents must stop--it is then essential that management promulgate. and follow through, a plan that will definitely fix this decision in the minds of all the individuals who collectively comprise the industry. The follow through must be such that department heads, superintendent*, and every member of the supervisory force will appreciate the need lor a constant, active interest in safety; will understand that passive interest will no more produce results Ilian would the same interest in production. Supervisors must be made to feel that the prevention of accidents demands the same type of heads-up super vision that is given to the other problems affecting cost and service. The executive must find a wav to indicate directly that it is the responsibility of the department heads to carry out management's program, that authority is placed itt each superintendent s hands to put accident pre vention on the sarttc basis as production. A complete.factual and descriptive report of each accident must be made. This must be followed by a thorough analysis to find the direct and underlying causes and the pro cedure necessary to prevent a recurrence. Proof of its sincerity will depend pri marily on whether management will make tlte first essential move in the program-- that is, authorize the cxiictidilure of money necessary to make the maintenance and op erating plant a safe place to work. Safety and Efficiency Analysis of the underlying causes of in dustrial accidents and preventive measures to be applied has made it increasingly appar ent that those factors which arc producing accidents arc very largely the same factors which tend to lower the quantity and quality of production. Expressed in another nay. Safety and efficiency arc as inseparable as though one word. In coupling satcty with efficiency I have not minimized it as an executive problem, but have endeavored to indicate that its solu tion is an executive responsibility, both to liis individual industry and to the employees that make it a going concern. Rail transportation is a scientific business in which laboratory research, expert engi neering, trained builders, and skilled workers sltare a part. One of the main factors is a group oi empluyecs who arc loyal--who appreciate that their railroad must give tiic kind of service that wilt stimulate amt accelerate the development of the territory traversed. The successful solution of our problem de mands the type of aggressive individualism in executive leadership that will attract and eotnmaiid'loyal, collective , cooperative effort on the part of all who produce rail transpor tation. Our major concern is leadership--leader- fm tdo February (0. 1994 T hereby certify that the attached copies of the Bulletin of the American Ceramic Society.
