Following up the meeting of companies interested in the Foundation's KW8 -0 10867 survey of Sick Absenteeism in Industry which was held here on May 27 Dr. William KW8-01867 KW8-010867 Gafafer Senior Statistician of the U.S. Public Health Service gives the following summary and instructions The May 1940 edition of the manual on a proposed plan to record industrial absenteeism was distributed at the meeting of Way 1940 among the rep resentatives of various member companies It was explained that the plan as presented in the manual was the objective which should be aimed at and that at the present time sufficient data be supplied by the companies agreeing to cooperate to make possible the construction of a table on ended disabilities lasting 8 consecutive calendar days or longer and showing for each color and sex 3 morbidity rates by cause namely average annual number of absences per 1,000 employees average annual number of days per employee and days per absence This table would cover the first and second halves of the year and the whole year The corresponding indexes for all report- ing companies would be included in the table for purposes of comparison Thus for the time being rates by age occupation and department are being reserved for the future and only disabilities of 8 consecutive calendar days and longer are included To calculate the rates referred to above the filling in of Forms A and B will not be necessary However for the calculation of the rates at least the number of employees under observation the absent as well as the absent are required by sex and color if the age distribution by color and sex is conveniently ascertainable it should be made av ilable since such knowledge would be helpful in any attempt to account for rate differences among companies It is suggested suggested however that age be filled in on the punch card if a company finds it convenient to fill in occupation and department consistently it is recommended that this also be done It was indicated at the meeting that some of the companies have the facilities to perform their own tabulating Such companies are encouraged to do so and for the sake of uniformity a blank table and other instructions will be sent to such companies Those companies that are at present reporting to the United States Public Health Service are urged to continue this activity and where possible their data ill be used to supplement the reports from the new companies In order that we may plan accordingly will you please advise us at this time of the number of male and female employees you desire to report on Also to facilitate comparisons of absentee rates of different companies it is necessary to know something of the disability plans companies have in force Will you therefore send us a copy of any pamphlet or other material that may have been issued by your sick benefit association relief plan or insurance company which covers such subjects as requirements for membership waiting period benefit period classes of membership etc. As soon as this information is received from companies desiring to participate we will be able to proceed with the punch card and we will communicate with you regarding the number desired cost they are about 1.00 per thousand etc. Reduction of sick absenteeism is doubly important now when production is the keystone of defense 1992 1992

to work for bigger profits In addition to making possible substantial savings music in industry has become one of the most modern and successful ways of cementing mutually beneficial employee relations having won the commendation of both labor and industrial chiefs In one company the bonus a comparatively expensive method of stimulating output was able to add only 20 per cent while music cost- ing much less added 25 per cent Because of that the bomus has been discontinued but the music remains a permanent part of production routine and has worked satis- factorily over a period of

For this injury the employee was paid compensation A few days after the operation pleurisy developed but this seemed to clear up and he re turned to work about eight weeks after being discharged from the hospital Thoug continuing at work the employee steadily lost weight complained of pain in the abdomen and was always tirod and his appetite was impaired On Jan. 25 1937 th employee underwent another operation and it was then discovered that a gastric ulcer had perforated the stomach He died five days later from general periton- itis There was medical testimony to the effect that the treatment of a gastric ulcer consists essentially of rest freedom from worry and generally building up the body vitality that worry is one of the prime causes of increas- ing the acidity of the stomach juice which is a prime cause in speeding up the cause of ulcer if not causing it that if the employeo failed to regain his health following the injury we have all of the factors which would have activated a existing ulcer or speeding its course whenever it developed and that therefore the perforation of the ulcer was directly connected with the indus- trial injury suffered by the employee Although said the Supreme Court the testimony of the medical experts relied on by the department may not seem convinc- ing a court is not at liberty to weigh it or pass on the preponderance Rickard v Bridgeman Co. et al Mich 284 N.W. 689 Workmen's Compensation Acts Compensability of Death Following Mental Overexer- tion J.Am.Med.Assoc 114 1955-1956 1940 The employee was a timekeeper for the defendant company During the latter part of July 1934 at a time when the temperature ranged from 87 to 90 F. he worked steadily for twenty hours in an effort to locate an error in the payroll records Just as the error was discovered he slumped in his seat and died The industrial board awarded compensation to the employee's widow and children on a finding that twenty hours of continuous work constituted extraordinary exertion and that this extraordinary exertion is indirectly and causally connect- ed with and responsible for the death of the decedent said exertion and great mental effort coupled with the fact that the decedent suffered from arterio- sclerosis resulting in his death from a cerebral hemorrhage The court of common pleas Montgomery County Pa affirmed the award and the employer appealed to the superior court of Pennsylvania In sustaining the judgment of the trial court the superior court said The novel feature of this case is that the overexertion relied upon was more mental than muscular We see no reason for holding that the overexertion which may make an injury or death resulting there- from compensable must be solely physical in character Authoritative definitions of exertion do not confine its use to muscular effort .... As expressed by the court below there is no fundamental difference in law or principle between an injury or death caused by the cutting or crushing of a blood vessel in the brain through the application of external violence and the breaking of one through in- creased internal pressure due to the putting forth of an unusual or abnormal mental effort The employer appealed to the Supreme Court of Pennsylvania Of the five medical experts called the court pointed out four testified unequivocally that it was impossible definitely to establish any relationship be- tween the oxtra hours of work and the death The one physician who attempted to establish such a connection succeeded only in showing that overexertion could have 76617661 7661 76617661 76617661 JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON JOqWOAON ABRAMS ABRAMS ABRAMS ABRAMSABRAMS ABRAMS ABRAMS ABRAMS RE RE RE IN Digest of Industrial Hygiene - 4 499 brought about the death To say therefore that death resulted from long hours MW88-0018872 of work the court concluded was at most a pure guess The judgment of the MW88-0018872 superior court for the claimant was therefore reversed and judgment entered for MW8-01872 the employer 889 Monahan v Seeds & Durham et al Pa 3 A. 2d 998 6A 20 MW8-01872 MW88-0018872 MW88-0018872 MW88-0018872 Workmen's Compensation Acts Disability Resulting from Inhalation of Paint Fumes Not an Occupational Disease J.Am.Med.Assoc 114 1956 1940 During the last four months of his employment as a motal worker and upholsterer the workman was exposed about four times a week for short periods time to paint fumes discharged from a spray gun used by a fellow worker On several of these occasions he became ill After such an exposure on Oct. 9 1937 he was forced to quit work and procure medical attention In proceedings which he subsequently instituted under the workmen's compensation act of Oklahoma based on an allega- tion that he had sustained an accidental injury as a result of the exposure to paint fumes the two physicians who attended him testified that he had a vas- omotor disturbance brought on by the exposure to paint fumes Medical ovidence offered on behalf of his employer and the insurance carrier according to the reported decision definitely excluded any claim that respondent the workman might be suffering from an occupational disease The industrial commission awarded him compensation and the employer and his insurance carrier obtained a reviow of the award in the Supreme Court of Oklahoma It was contended among other things that the disability of the workman was due to an occupational disease and not to an accidental injury and that a finding by the industrial commission that that disability had resulted from the inhalation of paint fumos established as a matter of law that an occupational disease was the cause of the disability While it is settled in Oklahoma said the Supreme Court that cam- pensation may not be awarded for a disability which results from an occupational disease that prinicple is not here applicable since the medical evidence adduced by the employer and the insurance carrier definitely eliminated from consideration any contention that the workman might be suffering from an occupational disease It is likewise a settled doctrine in Oklahoma that the benefits of the workmen's compensation act are not confined to cases of traumatic injury and that inhalation of vapors gas or dust may constitute an accidental injury within the meaning of the compensation ect The Supreme Court believed accordingly that there was competent evidence before the industrial commission to sustain a finding of acci- dental injury The award in favor of the workman however was vacated on other grounds not here material Ross v Ross Okla 89 P. 2d 338 500 Heat Exhaustion Whether Employee Must Be Exposed to a Risk in Excess of that to Which Other Manual Laborers are Exposed Because of Hot Weather The trial court held that if the injury resulted from heat exhaustion in the course of the employment and would not have occurred but for the employment at manual labor on a hot day it arose out of the employment Such are not the terms of the Workmen's Compensation Law nor the construction given it by this court This court has followed the line of cases holding that where death en- sues from heat exhaustion it does not arise out of the employment merely because it resulted from manual labor not involving unusual strain or overexertion in the employment The employment must expose the employee to a risk in excess of that to which other manual laborers are exposed because of hot weather Gulf States Steel Co. v Christison 228 Ala 622 154 So. 565.

Plaintiff worked for the defendant company from 1922 to 1926. He claims that he contracted pneumoconiosis but that this fact was not ascertainable until 1934. The jury returned a verdict for plaintiff for 8000 Plaintiff remitted 500 From the resulting 7500 verdict and judgment defendant filed a motion for new trial which was sustained Plaintiff has appealed The vital question raised here on appeal is whether or not plaintiff's action as a matter of law was barred by the five years statute of limitations sec 862 Rev. St. Mo. 1929 But under the provisions of Section 860 Rev. St. Mo. 1929 plaintiff's cause of action shall not be deemed to accrue when the wrong is done or the technical breach of *** duty occurs but when the damage resulting therefrom is sustained and is capable of ascertainment and if more than one item of damage then the last item so that all resulting damage may be recovered and full and complete relief obtained Plaintiff testified that he worked for the defendant company from August 9 1922 to May 5 1926 that his work was that of grinding chipping and filing metals that there was some one grinding all the time and a constant cloud of dust pervaded the room that the fan never operated very well that it was out of repair most of the time that no signs were posted and that he was not warned of the danger of inhalation of dust that no medical examination was made of him at the time he began to work or thereafter that no respirators were furnished him Plaintiff's testimony was corroborated by three witnesses each of whom had worked for the defendant during part of the time that plaintiff was working for defendant In 1926 plaintiff left his employment with the defendant company be- cause his health was getting bad Thereafter plaintiff did not engage in any kind of dust work Dr. Young testified that he had had a great deal of exper- ience in dust diseases that from ray pictures taken of plaintiff in 1934 he found that plaintiff was suffering from pneumoconiosis that he had examined all of the ray pictures taken of plaintiff from 1929 to 1933 in the several hospi- tals in St. Louis and that he found nothing in those pictures that would warrant a diagnosis that plaintiff then had pneumoconiosis that he found that plaintiff was suffering with said disease only from the ray pictures which had been taken of plaintiff in April 1934 and that therefore in his opinion the fact that plaintiff was suffering with pneumoconiosis was not ascertainable until sometime between October 3 1933 and April 4 1934.

F.F. Kravath Heating and Ventilating 37 17-21 Study of the Elector June 1940 In an effort to answer questions which might be raised by an engineer the author conducted a series of experiments on what is considered the most efficiently shaped venturi ejector The results indicate that the induced air volume is vir- tually a straight line function of the jet volume Resistance applied on the induction side of the ejector resulted in an expected decrease in induced air volume Under identical conditions a 2 inch jet induces 600 of the air of a 6 inch jet and 250 the volume of a 4 inch jot Howover as the induction resis- tance is increased the relative superiority of the smaller jets decreases some- what but at free delivery it is possible to induce an air volume of approximate- ly 5-1 times the volume of the jot air The author emphasizes the reduction of resistance at the ejector discharge to an absolute minimum Even a small amount of additional resistance such as would only decroase the induced air by 25 to 40 if applied at the induction or secondary end is enough to destroy completely the effectiveness of the ejector if applied at the discharge end In fact not only is there no air induced but some of the jet or primary air actually reverses direction and comes out the secondary end This can be avoided by making any length of pipe as large in diameter as is practicable elbows should be of the long radius multi type and weather caps should be streamlined to avoid unnecessary shock losses If resistance cannot be avoided the jet velocity must be increased 520 Determination of Carbon Disulfido in Air F.F.

Strock Heating and Ventilating 37 This is a description of an extensive exhaust system for 235 pieces of equipment by which the author terms a strikingly smart and clean job of engineering One section of the building required the exhausting of grinding machines the other where heat treating and hardening was carried out necessitated the removal of gases from the numerous furnaces A remarkable feature of the oxhaust system serving the grinding department is the almost total absence of visible duct work This is achieved by carrying the exhaust connection under the floor to a main located under the aisle and thence to a riser located along the side wall of the building As the risers are relatively flat and located along the wall they are practically unnoticed The method of concealing the branches and main duct under the floor is illustrated The problem of clean doors in the under- floor duct system was nicely solved On the roof are 15 banks of dust collectors consisting of 92 units capable of handling 92,000 c.f.m. oach bank serving an aisle To maintain a constant static pressure the filter bags are cleaned automatically by a pneumatic shaking mechanism which agitates the bag The heat treating equipment is arranged longitudinally through the hardening room An enclosure was built in front of all the furnaces extending over their tops in order that they might present a uniform appearance and be heat insulated from the working space Each of the furnaces is heavily insulated Three exhaust systems serve the furnaces and have a combined capacity of 58,100 c.f.m. Gas explosions are eliminated by automatic gas escape valves The ducts are also provided with back pressure dempers to prevent the fan from discharging back into the building when one is shut down - this also prevents heat loss by stack action Where the vapors are hot and liable to discolor an inside casing with air space is pro- vided This system effectively eliminates any potential hazards without obstructing light or sacrificing appearance In the author's words It is no overstatement to say that the exhaust systems in the Ford Tool and Die Shop approach the ultimate in good plant housekeeping" 523 Triangle of Responsibility June 1940 A.S.

L^,derer and F.C. Bing J.Am.Med.Assoc 114 2457-8461 June 22 1940 Studies made with young albino rats lead to the conclusion that the amount of lead stored in the body is decreased when calcium carbonate is added to the diet Phosphates have no significant effect Lead is found stored chiefly in the bones and the kidneys have relatively high contents compared to the liver Calcium appears to exert its beneficial action by preventing the absorption of lead from the intestinal tract as the calcium in the diot seems to have no effect on the retention of load administered by injection into the abdominal cavity 538 The Biochemical Behavior of Lead I. Influence of Calcium Phosphorus and Vitamin D on Lead in Blood and Bono A.E. Sobel H. Yuska D.D. Peters and B. Kramer. J. Biol Chem 132 239-265 1940 1. Experiments were designed to study the influence of diotary Calcium Phosphor- us and vitamin D on the biochemical bohavior of load in young rats The diets used varied with respect to these three factors but were similar in their lead content 20 The results show that influence of all three dietary factors namely Calcium Phosphorus and vitamin D must be considered in the biochemical behavior of lead 3. Lead deposition in the bones may be explained by post- ulating that lead phosphate and vitamin D form a system of lead deposition analogous to the system of calcification The addition of Calcium tends to re- move Phosphorus from the system for lead deposition 4. Blood lead values obtained may be explained by assuming a relationship between blood lead and dietary lead to Phosphorus ratios similar to the relationship between blood Cal- cium and ~ ietaryCalcium to Phosphorus ratios The influence of vitamin D upon blood lead is similar to its influencoen blood Calcium on corresponding distory metal to Phosphorus ratios 5. It was experimentally demonstrated that simultaneous lead deposition and removal of Calcium from the bones is possiblu Furthermore it was shown that increased calcification does not necessarily mean increased lead deposition 6. It is concluded therefore that lead deposition is directed by a system of its own which is governed by the same laws as is Calcium deposition but does not necessarily go in the same direction The effect of Calcium on the deposition is essentially competitive because it tends to re- move Phosphorus available for lead deposition -- Author's summary 539 A Single Trauma as an Etiological Factor in Carcinoma W.E.

Smyth Sr. American Public Health Assoc Bulletin 3087 16 pp October 18 1939 There have been 1,683 cases of anthrax with 353 deaths in the period 1919 1938 Since 1928 there has been a decrease in the number of cases but this has pro- bably been due to the industrial depression with a corresponding decrease in the number of employees and also in imported hides and skins with a greater use of killed hides which are usually from Government anthrax animals Further proof of this is to be found in the fact that the decrease comes only from industrial groups The drop in fatality rates comes practical- ly all from the cases in organized industries where earlier diagnosis more prompt treatment and extensive use of serum and arsenicals are employed This report shows that there is still a decided need for prophylactic measures to be taken in the prevention of anthrax If hides and skins the largest single cause of anthrax had been properly sterilized there would have been saved in the 20 years a large number of deaths and over 10,000 days lost time but as yet there is no accepted method for carrying out such sterilization 548 Photosensitization Phenothiazine F. DeEds R.H. Wilson and J.O. Thomas J. Am Med Assoc 114 2095 2097May 25 1940 This substance is one of the more promising organic insecticides developed as a substitute for lead and arsenic Reports of irritation among men using it for spraying purposes have been made although laboratory workers have used it with impunity and it has even been administered orally as a urinary antiseptic with- out untoward results The explanation for this seeming contradiction apparent- ly lies in the products to which the substance is oxidized in the body After oral administration phonothiazine is oxidized to the reversible oxidation tion system leukothionol This system will sensitize individuals to sun- burn The fact that the orchard workers who use the spray are subjected to environmental conditions sharply contrasting with those of the tested laboratory workers and hospital patients is also a determining factor in tracing the source of the difficulty Laboratory tests conducted on the basis of these facts showed that the trouble was due to the resulting photosensitization and not to local irritation by the phenothiazine 549 Cheilitis and Dermatitis from Toothpaste L.B.
