After a careful survey, the town of Thetford Mines, an asbestos mining center in the Province of Quebec, was selected as the seat of the experiment. A French-speaking npularcseedwiinthchexatregnesaivnedexapsseirginenedceainstmaaffteornf ittwy ocenotthererwoFrrkenwcahsCanadian nurses and later a physician, all of whom were given special training in New York City. As a result of the three-year experiment, the infant death rate in Thetford Mines has been reduced from 338 per 1000 to 96.4 per 1,000. Another gratifying outcome of the experiment has been that because of the results obtained in Thetford Mines, the Pro vincial Government of Quebec has appropriated $500,000 to be used during the next five years in child welfare work in the province. THE INFLUENZA COMMISSION Because of the enormous loss of life that occurred during the influenza epidemics of 1918 and 1919, the Metropolitan undertook to finance a study of this disease, about which so little is known. A commission composed of five of the leading sanitarians of the country and two representatives from the Company was organized. All of the research work on influenza being carried on in the country to-day is mobilized under this commission. butTehnucsoufarragthinegcraeussueltosf hinafvlueenbzeaenhaosbntaoitnbedeenindestteurdmieisneodf, (81 . #- TO De, t r i tot s c o l i l i DP >; flO lli Ir U om 0131 Barato 81, 1827.

P lw n t. All of the dust counts in this plant show less than ten million particles per cubic foot of air sampled. Trhile these counts are not considered as dangerous concentrations, they are much higher than on the previous survey made in 1930, with the exception of those in the warp room. All but four of the looms have been moved to different locations since the first survey. A check of the records, would show a comparison of tbo type of y a m used and rate of production at the time of the two surveys. Semple #15, taken at the inspection table on the second floor shows the highest count. The concentration at this point could, be decreased material ly by the proper exhaust equipment. The present system is not designed property to take care of the dust generated. Sample #34 shows the presonce of lead. This amount is not consid ered dangerous, but it would be advisable to have the workmen at these looms examined periodically for qny signs of lead poisoning. The only sample in the L `, Brake Department showing lead was sample #29 This is not considered a danger ous amount, but does indicate that there is a potential hazard present. v-J- 3* i i f i " .

The molded type brake lining is made in two different processes. 4 One typa is m&da by mixing asb8to8, rubber, lithrrge, mica, whiting, sulphur, zinc oxide and high test gasoline in a mixer. This mixture is formed into sheets by ordinary rubber mills with heated rolls. The sheets are cut into strips for brake lining. The second type is made of a mixture of rubber, asbestos, lith arge, sulphur, zinc oxide and resin. This dry mixture is made into sheets by means of an hydraulic press. The sheets are cured in steam-hsated presses. Strips for brake lining are cut from these sheets.^ Both types of lining are ground to width and thickness on Gardner grinders or Blanchard grinders. The HrHng is-formed into arcs in heated presses and holes are drilled for rivets on automatic drill presses. Molded type clutch facing is mads from asbestos board. Asbestos ' .and water are mixed in beaterB to a pulp. This pulp is made into sheets on wet process machines. The sheets are dried in ovens and rolled to thickness in calendars The large sheets era cut .into strips from which the clutch facing rings are punched. The rings are impregnated in large tanks. Different speci fications call for different saturants. The rings are ground to thickness on. Blanchard grinders. The inside diameters are ground in internal grinders and the outside diameters are ground on external grinders. Rivet holes are drilled on automatic drillers. Tha finished clutch facing is then inspected -1 0 - 1 % before packing for shipment. Shoot packing is made from a mixture of asbestos, rubber, litharge, whiting, sulphur, zinc oxide and high test gasoline. These materials are miked in closed miaers. The net mix is nur.do into largo sheets in mills with heated rolls. It is either sold in largo sheets or it is cut into gaskets or rings on punch presses. The vapor arising from tho heated rolls, due t to tho gasoline, is collected by hoods and pipes and reclaimed in two large con densers.

This is accounted for by the method of handling the fibre and not t'na opunor itself. The fibre is dumped from bags onto tho floor and then shoveled into tho opener. The fibre is carried to a hopper above and then falls through a pipe into a truck which is located about six feet from tho opener. The operator stands between tho opener and the truck and shovels the fibre into the opener at the seme time that it is falling into tho truck. Tho dust concentration at this point "could be decreased by the proper handling of tho fibre. Samples #2, 3 end 4,show that there is lead present in the air at the88 points* While theso samples do not show a dangorous amount, it would be well if the workmen engaged at.these places were examined periodically for signs of lead poisoning. Notice was taken at tho time of this, survey of the method of ing litharge. This material is handled carelessly as it can be found #13 lying on the floor in the room whereI it is weighed and around the mixers. Sample shows a low count. Three men were engaged in filling the beaters* Practically all of the material put into the boaters was waste asbes tos board. Very little raw asbestos was added. No doubt the count at this position would be higher if more* raw .asbestos fibre were used out of tho bags* It is recommended that the bags of asbestos fibre be stored in a room isolated from the remainder of the plant. This would eliminate dust gonorated in tho p<Hng and unpiling of these bags in the room and exposing more people to the dust'than is necessary. Samples #15, 2J>, 28, 30, 31 and 32 all show that lead was present in the air sampled. Sample //30 is the only one that approaches a dangerous amount. -13- This sample also shows a high dust count. The high dust count at the two Blanchard grinders.#3 and 4 is due to the method of handling the brake lining during the grinding operation. Thi3 lining is the P.G. molded type and a * number of strips are placed together for grinding of the edges. After the edges are ground on one side, the operator blows off the clinging dust 7/ith an air hose and reverses the strips to grind the opposite edges. This type of grinding should be done on the grinding machines designed for this particular work* It was observed that a great amount of the dust present in the air is caused by the handling of the material after grinding. Dust clings to the individual pieces, and when the stacks are moved about they are not put down carefully This results in dust clouds arising. Samples #25 and 26 show high, counts, targe size brake lining was used at the time these samples were taken. It was observed that the exhaust hoc d on machine #105 did not catch all of the dust from this type lining, fihen pmail^T. sizes of lining are ground on this machine the hood seems to catch most of the dust generated. The hood should be changed to take care of all sizes of lining ground on this maohino. -14- HEALTH HAZARDS Asbestot? dust gives rise to a pneumoconiosis or fibrosis of the lungs which has been discussed in the previous report mcde on the vsbestos industry. Developments in our knowledge of asbestosis are continually taking place and a summary of any new facts discovered will be added to the general composite report of the asbestos plants survey which is to be brought out later. Mica belongs to the class of materials in which silica occurs in a combined form known as silicates. Little or nothing is available in the literature with regard to the effects of this dust on the lungs, though it seems likely that it belongs with the more mildly injurious dusts. Our present know ledge of the effects of the silicates is meagre, but work is being carried on in various quarters in on attempt to determino their classification more accur ately with regard to health. Experimental investigation of mica dust was made recently by A. Policard of the University of Lyons, Franco.^ ^ His conclusions from observations on white rats were that these dusts are noxious to the lung tissue, resulting after a time in changes in the cells and in phagocytosis and producing a mildly chronic fibrosis similar to that seen in silicosis. Mica particles grouped in plaques were found in the alveolar tissues. With his conclusions regarding the theory that sericite is the chief factor in the causation of silicosis, authorities in this country cannot agree, although the matter is constantly receiving attention. of Lead) Toxicity of Lead in Rubber Mixing (Litharge - red or yellow oxide Compounding and mixing are the most hazardous processes in rubber making. If these processes are properly isolated from the rest, compara- (l)Policard, A., The Action of Mica Dust on Pulmonary Tissue, Journal of Indus trial Hygieno, Baltimore, Vol. XVI, No. 3# May, 1934, PP* I6O-I64. -15- tively few workers need remain exposed. Lead poisoning is the commonest of the industrial intoxications. The i ' toxicity of lead`depends upon a number of factors such as : the form of lead taken into the body - vapor, dust or solid; the solubility of the lead compound in human tissues; the mode of entry of lead into the body - inhalation, ingestion or skin absorption; tho extent of exposure; individual susceptibility which is heightened by numerous conditions particularly by previous attacks of poisoning. Among the most readily toxic of the inorganic lead compounds are the oxides, the carbonate, the sulphate and the chromate. Lead is a cumulative poison and, with a few exceptions, industrial lead poisoning is usually a chronic condition caused by the inhalation or in gestion of small amounts of soluble lead over long periods of time. This process of poisoning may go on slowly for a long period without manifesting any of the characteristic acute symptoms. Lead inhaled., however, is far more rapidly and purely toxic than load ingested, since it reaches the blood stream more directly and comparatively little is eliminated uncibnorbed* There is little agreoaenb in the estimates made by various authorities on the nrirdmum amount of lead which can cause poisoning if taken into the body. For practical guidance, however, it can. bo assumed that from 1 to 2 milligrams taken in daily over a period of months or years may cause poisoning. A number of factors also enter into the estimation of-the amount of air breathed by a at active work during the working day. Ten cubic meters of air in a ten hour day is an estimate which very probably errs on the safe side for the average workman. On the basis of these calculations, the lead content of the air of workrooms where men are continuously exposed should be kept as low as ** -1 6 - 0.1 of a milligram per cubic meter of air or* elso strict measures for protection should, be installed to prevent poisoning. The symptoms of chronic lead poisoning are many and may manifest thnraoolvQB through tho giifitro-lntontlnnl tract an In the familiar "loud collo" or the neuro-muscular system or both. Among tho symptoms most commonly noted are colic, metallic taste in tho mouth, obstinate constipation and loss of appetite, muscular weakness, particularly of the hands and wrists, neuritis and joint pains, loss of weight, headache, dizziness, nausea or vomiting, gastric distress or fatigue are among tho minor symptoms that may or may not be present. The principal diagnostic signs for the detection of lead poisoning . / in its early stages or of lead absorption, which is essentially pre-clinical poisoning before the onset of symptoms, are ashen pallor of the skin, tremor, lead line on the gums, stippling or basophilic degeneration of the red blood cells, homatoporphyrin in the urine and mild secondary anemia. Other abnor ( malities ia the blood which are characteristic of lead poisoning are polychro me tophilia, changed relative proportions of lymphocytes and polymorphonuclear leukocytes, Increased mononuclear cells and increased reticulocytes. Repeated physical examinations should be made of workers exposed to load at fairly short intervals, of from two to six months, depending upon the severity of exposure. It is important to prevent the occurrence of lead poison ing, since, even though it is not often fatal under modern conditions, it fre quently results in premature development of chronic degenerative conditions in the circulatory system.

It^ has been established that the maximum allowable concentration for i prolonged exposure is 100 parts per million. Because of its recognized and very: ( soricus danger to the health of operatives, its use as a solvent in spray coating I I operations has been largely supplanted by less toxic substances or by its less ; harmful homologues toluol and. xylol. These substances are not necessarily less dangerous to life if breathed in, but, because of a lower volatility and a marked' odor, they are less likely to escape unnoticed into the atmosphere. More- \ over, they do not damage the blood forming organs causing chronic permanent injury to health to the same extent as does benzol. Solvent naphtha derived from benzol is a mixture of toluol and xylol and in the same class with these substances with regard to health hazard, while petroleum naphtha is classed with benzine, gasoline, the chlorinated hydrocarbons and with the alcohols, acetates and ketones, and with which severe poisoning is rare. Whether or not these sub stances have any action on tho blood is still controversial. Usually poisoning by them is of the acute anesthetic typo. Tho effects due to exposure to heavy fumes are headache, nausea, dizziness, blurred vision, mental confusion and loss of consciousness. These effects generally disappear fairly quickly in fresh air* Chronic effects from prolonged exposure are less definite but similar, with muscular weakness, tremors, and various nervous disturbances.

As is the case with benzol, the toxicity of methanol has been blamed on its impurities, but there is ample evidence of a sound nature that methanol itself is the chief toxic factor. The effects of the vapor, accumulating as it readily does in the body, are directly poisonous to the nervous system, and have a special affinity for the retina. Large doses cause prolonged coma, U ) blindness and death. The m i n i m a l toxic dosage is not veil established. Hender- son and Haggard quote Loewy as putting it at 200 parts per million for ex perimental animals if inspired over a long period. It has been recommended that the concentration should be kept below 1 part per 10,000 parts of the air, or (5) 100 parts per million.

Practically nothing is known regarding the possible effects of bakelite dust on the re%piratory system.

Skin affections due to bakelite are of frequent occurrence and ore popularly known as "bakelite itch". The face and forearms ere most commonly affected in workers handling these resins. Skin lesions are especially prev alent under conditions favoring perspiration. They may be avoided, therefore, by provisions for good ventilation and by frequent washing of the exposed skin in alkaline solutions* Unusually sensitive persons should be removed from this type of work* L infififid jJL In addition to the danger of spontaneous combustion, linseed oil when heated gives off irritating fumes of acrolein. No chronic ill-effects have been noted from this substance though it is irritating to the mucous mem branes of the eyes, nose, and throat. ' The addition of resins to the mixture gives rise to volatile ethereal oils which have caused headaches, nausea and even stupor. Although Dr. Bnrnos'( 8)' in a study of linseed dermatitis did not find the pure oil as irritating as linseed cake, dermatitis or infections, especially of the hands are common in workmen who come in contact with either (9) of these substances. Workers showing hypersensitivity to the oil may have to be removed from the work. ________ (6) Sayers, R.R. and Dallavalle, J.M., Prevention of Occupational Diseases, Mechanical Engineering, April, 1935, p* 232 (7) International Labour Office, Geneva, 1928, Occupation and Health, Brochure #115, Bakelite.

There is attached our booklet entitled "Prevention of Oil Pimples" which describes some of the protective measures with which these skin troubles may be decreased. One of the most frequent causes of dermatitis in the rubber industry is hexamethylenetetramine used as an accelerator and paraphcnylendla mina or similar coal tar compounds. A one per cent solution of "hexy" is said to be sufficient to cause dermatitis and in hot weather skin trouble is almost inevitable if this substance is carelessly handled. It is not, perhaps, sufficiently well understood that continued exposure to certain of those skin irritants may develop a eevsitivity in workers who did not at first appear to be susceptible. Once dermatitis from "hexy", for instance, has occurred, the individual is sensitized to the substance and, much as with poison ivy, is unable to tolerate even slight exposure there after without skin outbreaks. Heat usuelly quickens the reaction. Protective ointment -containing alkali has been recommended. 4t ' Park, oily-skinned persons are usually more resistant to the irritating effects. Those having frequent outbreaks of dermatitis or those found sen sitive to these substances through patch tests should be transferred to other I occupations - <r -hr,. -2 1 - Protective work clothing with provisions for changing it and good facilities for washing, together with tho enforcement of rules regarding persona] (10) cleanliness, helps to prevent both slcin troubles and cases of poisoning, Chrome. t Chrome compounds and the health hazards associated with them are dis cussed in the accompanying booklet "Protection of Workers Exposed to Chromium and Its Compounds" t ...
