Public Health Service which is intimately concerned with the activities of this Conference as well as with the state agencies administering industrial hygiene is urging the development of a code of the the probably take type outlined in present discussion Such a code will considerable several years of effort although a considerable amount of information is already at hand for inclusion The main problem as we see it will be to obtain unanimity among the various states It is felt that if such a code is based on scientific fact and is so worded that it takes into consideration the various social and economic aspects of the problem then it should meet with great favor among the state agencies and the public This will be especially true if it is administered in a spirit of cooperation with manage- . ment and labor { 100 20 4 100 400 . 0 100 75 c 0 100 10 : 0) 100 100 0 100 15 0 300 3 .

HATCH Research Director Industrial Hygiene Foundation President American Industrial Hygiene Association of representative in number MR STOCK employees this word communities first idea that comes idea When we asked the citizens a should a plant do for its What into their mind is security To a large the extent very Field research undertakings by the Foundation during the past year a nice tasting word to the American public having no But fairly large portion of the public use the word have exceeded the work of previous years in magnitude and scope as well a healthful and safe jobs as in the number of projects Studies have covered a wide variety of repre- fourth industriAal Security good working conditions general mention specifically that sentative industrial problems ranging from investigation of underground of amounts and composition of wastes dis- fourth fourth should public employees clean places to work good light- operation to measurements plants plants employees good drinking water safety devices of all charged from stacks A few undertakings were routine in nature requiring z , the use of highly standardized procedures for the correction of recog- nized hazards For the most part however the studies have been more the benefit of using ash one more question what do you find is telling the the formula of the story telling the story MR STOCK I you asked that Recently in a study of about about bottom 48 companies we made a comparison of the top 12 and the 12 in public vote in their We found that all top 12 in public vote their living right The management of not bother to interpret their good acts None basic even requiring entirely new procedures and having to do with broader problems than the simple discovery and correction of a hazardous exposure This is best indicated by the following list which summarizes briefly the primary objectives of some major projects SUMMARY OF PRIMARY OBJECTIVES OF SPECIAL PROJECTS than the bottom 12 had ever had a 1947 had one or more strikes within the numerous examples of the pay of adding good Notably we have observed cases where strikes shortened production increased and costly turnover pointed out that when people know that a plant they want to work there This has tremendous trying to hire and keep the most qualified workers . Coordination of dust control procedures industry 2 Over appraisal of industrial health problems and advice on organization and operation of industrial hygiene service by company 3 Preliminary investigations of new dust and fume problems to develop the needed research program for further study 4 Basic engineering analysis of operations with Engineering De- partment to develop sound design procedures for ventilation and , other control measures in place of empirical practices 5 Over study of operations in a chemical plant to provide the most effective layout and design of a new plant and equipment for maximum built control of hazardous materials 6 Development of an operator training program basic control measures and a continuous sampling and alarm system for a toxic gas which characteristically escapes accidentally rather than as a daily occurrence 7. Basic investigation of radiant heat in a hot industry to determine the primary sources and pattern of exposure with a view 23 to the development of more effective control measures and further improvement improvement of working conditions x, Further investigation of silicosis hazards and other dust expo- sures to provide more meaningful methods for distinguishing between hazardous and nuisance dusts and to give more meaning to occupational history as an essential aid in the diagnosis of chest ray films Industry Studies Foundation wahnidch of of expecial interest report last year was the number of projects undertaken or an industry Investigations of this type account The procedure is entirely for an even larger portion this year in keeping with the underlying underlying function of the effort of its members is to Further- industrial health through the joint promote when investigations are planned under- more the returns are greater An outstanding feature taken on the broader base of a joint undertaking is the advisory technical committee from the an industry ststudyudy investigation industry which set up to take part in the planning of the collecting detailed selecting the plants for study reviewing the data and information from the several plants in the group There is greater utili- within industry in respect to a common zation of the accumulated experience is possible utilize this bring the problem In single investigation investigation there little opportunity to single What is more important it is not to varied experience of different plants together for comparison and critical evalu- experiences ation when plant studies are conducted conducted separately The significance of these joint undertakings extends far beyond the enhanced value of the studies themselves themselves The free exchange of exper- manufacturing ences chemical and engineering data and even details of which has taken place in each case is a tribute to the sound policy processes and the high objectivity of the companies involved Recently the Mention has been made previously of the extensive studies conducted potteries during the past three years This year the Foundation was invited to al of the companies in the U.S. Potters Association for the of correlating the dust control work in that industry purpose conducted a Clinic on dust problems here at the Mellon Insti- Association of which was to discuss in considerable detail tute the primary purpose the dust control practices throughout the industry Other industries may find this a worth while procedure and the Foundation will welcome the opportunity to assist in such meetings Expenditures for Greatest Good Industrial hygiene is concerned with relationships between the health of environment industrial the worker and the stresses of his job and of the The actual practices of industrial hygiene are based upon the assumption borne out by research and experience that these relationships can be ex- industrial pressed in quantitative terms That is to say the effects of the environment upon the workers health can be determined from quantitative of the levels of exposure to offending substances or other measurements 24 deleterious forces present in the environment The factual and objective basis of industrial hygiene not only justifies its existence as a technical specialty but is of the greatest practical value since so far as possible it aims to substitute facts for opinions By means of quantitative analysis effort major health problems are distinguished from minor ones Important sources of trouble are identified so that in the health program money and can be expended for the greatest good A formidable array of instruments and analytical techniques have been developed which are capable of measuring environmental factors with considerable precision An equally extensive list of standards of permissible exposure have been proposed which make it possible in the appraisal of working conditions to determine whether or not health hazards exist These developments are the result of many years of research in the labora- Tory and in industrial plants The record of accomplishments in the practical solution of health problems in industry through the use of quantitative methods speaks for itself and accounts for the increasing numbers of industrial hygiene services being set up within industry Because of the excellent record of accomplishment there is danger that industrial hygiene methods may become too standardized and acquire a degree of scientific sanctity not justified by the researches upon which they are based This can be avoided only by constant critical review of the procedures and standards and continuing research Only in this way can the practical usefulness of industrial hygiene be extended and strengthened Research Needs Research needs are emphasized by our day plant experiences where situations are repeatedly encountered which differ in many ways from those considered in the original studies upon which existing standards are based The question constantly arises therefore as to the universal applicability of standards and procedures The following examples may be taken from the work this year 1 Shaver's disease is a pulmonary disease caused by fumes from the fusing of bauxite in electric furnaces for the production of synthetic abrasive The causative ingredient in the fume is not known Fume particles are microscopic in size and cannot be studied properly by analytical methods in common use 2 Asbestos dust exposures preliminary study of asbestos dust exposures using the electron microscope and other advanced techniques indicates the need for considerable further study of this problem and the development of new analytical techniques 3 Silicosis the many years of study of this disease much remains to be learned Present criteria of the silicosis hazard are limited to the simple determination of dust concentrations and percentage of free silica in the dust Little is understood about the importance of microscopic particles not revealed by present analytical methods no consideration is given to the possible influence of ingredients other than silica in a mixed dust variation in the physical state of the borne dust which may alter the fate of the dust in the respiratory system is not now taken into consideration Experienced roentgenologists emphasize 25 e SUMMARY OF ENGINEERING CONFERENCE* PROF PHILIP DRINKER Harvard School of Public Health Chairman Engineering Committee Industrial Hygiene Foundation Conference was held in 1945 and at that we present from various member companies yesterday we were just over 100. The inter- and I for one feel confident that these engineering are an assured affair and will occupy interests of the engineering personnel of our various is naturally we presented do other aunospheric pollution Our interest somewhat in diferent from that of the Legal Committee measure One engineering aspect was of American Air Filter Company who of the interests of clients in the purchas- in that way developed some very inter- Hemeon presented it from a slightly general discussion which ensued brought out still The next topie and was well in est these these summarized on roof ventilators by elicited some interesting discussions who pointed out that the interprimarily on heat dissipation from impurities The development of roof ventilators and installation was an important part of Mr. Dunn of Corning Glass Company on an conditioned suit intended particularly for protection against high radiant temperatures Details of that suit I am sure would be supplied by Mr. Dunn of the Corning Company The paper which followed was one of a general discursive and discussion nature in which everybody entered on procedures by which the engineering divisions of companies could be brought into the industrial ventilation picture When there are problems in industrial ventilation dust control and the like the plea was made that every effort he made to bring the proper engineering division of the company in question into the picture and not to have it handled by some other division which might very well be interested but not interested wholly from the engineering point of view The final talk was on dust valves gates feeders and specialized equip- ment in which a question and answer forum was held that interested all the members greatly Supersonic Measures for Dust and Fume Control supersonic agglomeration of dusts and fumes of the Ultrasonic Corporation of Cambridge Mass He indications of pilot plant work that they are now doing in carbon agglomovation in Texas . Upon being questioned by Mr. Tony of others of us interested in metallurgical problems he stated not applied it to metallurgical fumes but hope to do so suggest which holds considerable promise through the offices of the directly through the Ultrasonic Corporation in Cambridge Foundation After lunch Mr. Hatch presented general topics on exposure to indusheat and improved methods for appraisals of heat exposures and that was an interesting exhibition with some practical data by H4 November19 40 41 Transactions of THIRTEENTH ANNUAL MEETING INDUSTRIAL HYGIENE FOUNDATION OF AMERICA Inc.

Thompson General Manager and Treasurer of China Company and a member of the Foundation's Board of opened the mooring with an explanation for this conference as the first eramic meeting undertaken by the Foundation He re- viewed briefly the events leading up to this iaceting and expressed the it that if were sureossini it might become a regular feature of metingsmeetings He introduced Mr. W. Hazard Industrial Relations Division of Owens Dinois Glass Company Toledo Ohio as the boderator Agenda I Compensation for Dust Diseases ( Waters Chairman of the Foundation's Legal g Mr. Waters first discussed partial disability for silicusis GTA statel that 39 states have compational disease laws and they are divided IE divided on the as follows 22 provide limited compensation 17 allow none and 3 limit the payment of partial disability to a minimal finding of % states some measure of wage loss is used as determining partial disability In New York disability is briefly classified as inability to earn wages i i Wright Wright of the Saranac Laboratory conducted some riments the evaluation evaluation of partial disability It was his con- E is felusion that there to no sound medical evaluation method for F determining partial disability from silicosis In cases of simple un- nauplicated silicosis the employee though exhibiting lung changes wages this man should stay in his regular occupa- does bave a demonstrable injury but has had no disability Some suits for partial partil disability have been filed at common law in New York Pennsylvania and Utah but have been refused The ques- Thun has been referred to the Supreme Court but no opinions have been handed downr Labar is making repeated demands for legislative changes to corapensation for silicosis in all stages Three states have set up injury funds for the payment of partial disability benefits An examwas West Virginia in which state the compensation statutes at Webster Ball Plotel Pittsburgh November 19 1948 42 have established silicosis in three separate stages and made a compensation evaluation of each 1. First detectable ray but no disability Compeu- sation allowed in the amount of 800,00 other claims barred 2. Capacity for work impaired Compensation allowed in the amount of 1600.00 and other claims are barred Silicosis complicated with tuberculosis and disability Full compensation benefits allowed The state commission retains jurisdiction over all claims which can be reopened on showing of changed conditions Mr. Waters expressed the opinion that payment for partial disability is impractical and advanced the following reasons in support of his statements 1. It is impossible to medically evaluate lisability a Is the worker disabled b How much . 2. Compensation should not be paid until there is a wage loss 3. The employer's liability should be terminated within reasonable time New York state is conducting an extensive investigation of the question but no changes have been written into the statutes as yet Mr. Waters feels that with 44 states in legislative sessions in 1949 many such bills will be presented and of course some will be passed Questions from the floor Question Can lung function tests tests be used Answer Mr. Waters is not familiar with lung function testing to the extent where he can answer this question Question Was asked his opinion of the compromise settlement system used in Missouri Answer Is against compromise settlements since he feels that neither liability nor rights should be bartered away Dr. Paul Bovard added to the answer of the first question that lung function tests are not standard as yet and do not offer conclusive medical information Mr. T. F. Hatch Research Director of Industrial Hygiene Foundation had no opinion to offer on this question 43 ben : Ly z Le : 34 _ Thursday April 23 7:30 Committee Chairmen's Breakfast Meeting Cleve- land Room 9:00 Section Meeting - Medicine Studio Room EM- BASSY AUDITORIUM John C.
