Pausing in the midst of the greatest effort yet ex pended toward maintaining good health among industries' personnel, this closely cooperating group laid plans for its ex panded contribution in placing the dis abled veteran back a t work, discussed been produced is not anywhere near enough. We hope, and our expectation is that, by petition to the directive power of the War Production Board which repre sents the greatest concentration of power in any agency, to be able to buiid this back up to 60-odd millions of yards per month m the early part of 1945. There is, how ever, no human way by which we can make up what has been lost during this period, and we are informed on the best possible authority that 100,000,000 yards or more of that which we may have had, but never produced means only one thing, a number of United States soldiers will be without shelter in Europe this winter--no rumor--a fact. - medical and legal aspects of sickness in demnification, and explored opportunities for further medical, chemical, and en gineering contributions in the postwar workers' health program. This meeting points with emphasis to the many ramifi cations of industry's health program, to the diversity of thought now concentrated in these efforts, and to the enormous in terest of industrial management that has made possible present achievements.

Analysing Ford's experience date, Dr. Krieger said tYe believe th at in the placement of ndicapped veterans, personal'handling the veteran from the time be applies for job until he is placed,- is most aatisnory. This we have accomplished by ving one man assigned from th e m lyment Division to interview, and hire veterans. .. The ,,veteran is th e n 1re Ted to the Medical Transfer Departin t for satisfactory, placement. We also lieve that in many instances further cational training of Abe veteran, is eded. This training must b e indilualiy adapted to the disability of the teran. Rug weaving, broom making, .ther tooling, etc., are essential for the rcific training and coordinating of nerveiscle function. We sincerely suggest to agencies, federal, state, and local that a finite program of practical vocational labiiitation be instituted. This will enle the veteran to adapt himself more ickiy in industry and allow us more time spend on other cases.

' . .:We believe that most of.these men can readjust and perform as efficient an opera tion, as is expected of any employee. In May 1944 two of our engineers made a statistical study of the job performance of a group of 39 hourly rate veterans picked a t random throughout the plant, with the performance of a similarly picked group of 78 nonveterans. ".<The conclusion- from this study was, "T here is no .significant'difference in fore men's1ratings of performance on the job between veterans and nonveterans.'' Mr. Hendrix said: .. In our work with veterans we have been impressed with the great importance of home and. community influences in their readjustment; A good home eat; be a powerful positive influence, a bad one may undo anything we may try to accomplish in the plant. The human environment a man finds on the job is also a strong force for good or otherwise. I t is necessary to consider this factor in placing these men. Also, it means th at we must strive to build a spirit of understanding and teamwork throughout our organisation--one in -which veteran will feel atease and a t the same time not be coddled. In.such.an a t mosphere the men will find it possible to make use-of the valuable qualities they gained in service--courage, discipline, teamwork, and self-sacrifice. Mr. Jenkins reviewed the job placement plan used with considerable success at Harrison Radiator Division, General Mo tors Corp. His group was one of the earli est industrial plants to inaugurate a pro gram of job analysis to determine what the job required of an individual. The primary objective of the plan was to facili tate the placement of handicapped people generally and with the return of disabled veterana such machinery would be in force to expedite their placement. Among other plans which now have been prepared, Mr. Jenkins cited those of Region X II o f the War Manpower Commission, San Fran cisco, and the Permanente Foundation Hospitals in California, which cover ship yard operations on the West Coast. " They Dot only have a plan of job analy ses but also a matched plan of recording the individual workers' attributes, with the purpose of matching the one with the other," said Mr. Jenkins. ' `While oor experience is still limited we arc finding that information furnished by job analyses, together with individual worker information furnished b y ' the Medical Department, definitely facilitates placement. It is not foolproof', he asserted, "as individual judgment is still required to fit properly the worker to the job." ' ' Dr. Streets, reporting experience with the plan for job placement of disabled veterans at. Westinghouse Electric and Manufacturing Co., said: The returned soldier makes formal ap plication at the employment office and ia given at once a working rank equal to that held at the time of induction. A tentative designation of a specific job is indicated which not only conforms to the old job rank but which, at the same time, takes cognizance of the desires of the applicant. Following the completion of preliminary forms, the veteran is interviewed by a physician who not only performs a search ing physical examination, but who deals in considerable detail with the psychologi cal background which will affect trie working future of the veteran. The life history of the applicant is tactfully re viewed with the obvious intent of assisting the applicant rather than of merely ob taining irrelevant data of purely personal interest. Very little difficulty hae been encountered in obtaining all the desired information m the cases which have been interviewed. Should the particular case be of such character that psychiatric consultation is desirable, such consultation is obtained. Following the physical and psychological evaluation, an attempt is made to offer a type of work which will utilize the appli c a n t 's w o r k i n g e n d o w m e n t a n d which will, at the same time, minimize any traits which may constitute job-liabilities.

A personal interview follow-up on each case begins 30 days after employ ment. . - Medical and Engineering C. M. Peterson, secretary, Council on Industrial Health, American Medical Association, discussed recent develop ments in preplacement physical examina tions. The council membership repre sents a cross section of the medical per sonnel in industry and this group has assimilated considerable experience in terms of essential factors bearing upon such physical examinations. Recognizing th a t many small industries are withput full-time medical personnel. Dr. Peterson said their group desires to present the best procedure developed through 'experience to all physicians called uporrto judge the physical fitness of workers for jobs whether they are full-time industrial physicians, part-time, on call to o n ly a few p la n ts , or only occasionally required to make pre- placeznent examinations. ' , "Protection of Workers against Noise" was tl;c subject of a report by Hallowell Davis, associate profeasor ol physiology, Harvard Medical School. He arid: I t is 'generally accepted proposition th a t sufficiently long exposure to' loud enough noise causes impairment of hear ing, particularly for high tones. Tem porary partial deafness, lasting from hours to a few days, is easy to produce and more readily in some individuals th an in others. I t is now becoming clear that individuals also vary widely in-their susceptibility to permanent as well as to temporary impair ment of hearing,', particularly for nigh tones.

The picture was typical of "heat rash'' and it seemed probable to our medical consultant that crystallization of body Bait on the clothing caused the irritation. M r. Hemeon continued discussion of this paper emphasizing elements in the control of exposures to workers' health. , Proper design of industrial ventilation is nbnoet Completely" dependent upon industrial hygiene, as has been repeatedly illustrated in our work during 1944. ' For proper.cftsgn imptiee knowledge as to the c u d aourees of the contaminant, its toxidty and, frequently, existing concen trations. In many cases it is virtually im possible to proceed intelligently in the de sign of control equipment without the aid of industrial hygiene and its techniques. Investigations conducted in a sand washing plant, in and around the sand drying equipment indicated that there was no silica duat hazard in the plant. Dust counts were uniformly low. The fine silica duat had been largely removed in the lutriation process and it was there fore practically impossible m this equip ment to create important dust concen trations. In one plant where workers com-, plained of cold drafte our investigation'dis closed a high rate of exhaust ventilation, but no controlled means for supplying heated air to the room. 3ome supply air did, of course^ enter,-because the .whole building was under suction, but it. came in through doors when opened wijl erafcks in windows, and exposed" all workers a t benchee near the periphery of the building to cold air currents. Workers in central parts of the room, engaged at work-pro ducing excess heat and some-amok?, wanted the cool air for comfort, hut in the circumstances it would be at the expense of the comfort of the-other groups. . A system of heated air supply at a rate to match the volume being exhausted, plus an exhaust system to remove smoke from its sources in the central portion of the space was needed to provide adequate control.- Legal Section Opening the second day of the postwar industrial health program was a panel dis cussion of the legal section which was con cerned with disability and compensation.
