IS million workmen In heavy Industry. qj ' ' <33 CS 1 Beware of "Black-Outs" For months the Foundation has warned that, "Increased production increases health hazards----- demands greater precautions." In this connection comes a report from a member company headed "A ELACK-OOT OF SAFE PRACTICES" which discloses a 147^ increase in lost time accidents in February over February 1940 with only a 33^ in crease in hours worked. While the Foundation* s field is industrial health, rather than industrial accidents, the above experience is a significant warning. Remember, the Foundation can help you increase your precautions to safeguard employee health through industrial hygiene surveys, appraisals, of ventilating equipment and other services. A slogan of 1917 was, "Food Will Win the War." Today it Is more accurate to say, "Health Will Win the War." Dr. Haythorn Honored $ Dr. Samuel R. Haythorn, Medical Advisor on the Foundations staff, was re cently elected President of the American Association of Pathologists and Bacteriol ogists. Dr. Haythorn, who is Director of the Singer Memorial Laboratory, Allegheny General Hospital, Pittsburgh, was also elected Tice President of the International Association of Medical Museums. . m W New Members i" .. j Latest .companies to affiliate with the Foundation are Merck & Company and ] Hazel-Atlas Class Company, both well known organizations.' * i "Group Discipline" Can Eliminate Heed For Government Control 7^ -- S'! *>> vE U.S. Senator Alexander Wiley (Wis.) said in a recent address: "I prefer to see governmental control voluntarily applied on a cooperative basis with the individual and the group, or oven better, I prefer to see individual or group disci pline which is so effective that it eliminates, the need for government control-... . "As far as I know, the greatest achievements in safety have resulted from the organized effort of comparatively small groups cooperating with government rather than by arbitrary government control alone. In other words, the greatest advances in safety have resulted from intelligent self-discipline rather than arbitrary govern ment control....." The above applies with equal force to industrial hygiene. This Foundation represents voluntary, organized action by representative industrial concerns for the conservation of employee health. This is the American method of dealing with socio economic problems. Instead of 250 companies there ought to be 2,500 companies partly cipating in Air Hygiene Foundation. . Annual Index Issued for Monthly Digest Enclosed with this issue of the monthly Digest of Industrial Hygiene is the annual index for 1940.

O.H. Robertson. Physiol. Rev., 2lTll2-39 (January, 1941H The author reviews the modes of entrance, distribution and disposition of for eign material in the respiratory tract. First, the progress of foreign particles to the lung is impeded by thestnnous course of the nasal passages, the sticky mucous character of the surfaces, action of the cilia of the membrarie and the cough reflex. Disposition of the material that has entered the terminal respir atory units is less simple. The principal method is by phagocytosis by amebic cells, the type of cell employed depending upon the character of the foreign matter. Bacteria such as the pneumococcus arc handled by the polymorphonuclear leucocytes, which appear in great numbers. However, with mineral dusts, the large macrophage normally present in the region goes into action. They quickly engulf silica dust particles and carry them rapidly to lymph vessels and lymphoid tissue. On occasion the amebic cell degenerates, leaving the silica free in the parenchymal tissue. Y.'ith asbestos, the process is somewhat different on account of the large size of the dust fiber. Macrophages accumulate around the fiber and form giant cells in which the so-called asbestosis bodies appear. Inasmuch as the- lung appears to act as a filter for foreign material injected intraven ously, it has been suggested that the pulmonary capillary endothelium, carries on phagocytic activity. The evidence, however, is to the contrary. The seme is true of the cells lining the tracheo-bronchial tree. A bibliography of 155 re ferences is included. j 260 Asbestosis in Grinders and Drillers of Breke Bands. Brachmann. Arbeitsschutz, p. 172-4 (1940). (German). Brake bands arc made of sheets of asbestos, or are pressed out of asbestos waste products and a filler, impregnated with artificial resin. Afterwards the bands and plates are ground and drilled. In exony all workers in asbestos plants must be exemined annually. Clinical and x-ray examination of the grind ers, drillers and men who file individual pieces has shown a few light cases of asbestosis after 2 years' work, and in nearly all such workers after 5 years employment. 261 The Struggle Against Asbestosis Today. Ehrhardt. Arbeitsschutz. pp. 191-3 (1940). (German). The paper is a brief description of asbestosis, rather than an account of the struggle against it. The author states that no relationship was found between nasal dust filtering ebility and degree of asbestosis. 262 Methods of Avoiding tho Dust Danger in Asbestos Plants, Valid from August 1, 1940. Anonymous. Arboitsschutz7 pp. 263-5 (l940). (German)7 The new regulations concerning exhaust systems, established by the manufacturers, insurance association end Gorman factory inspectors, are described. The effi ciency of the systems must be tested by a representative of the insurance association. 263 Regulation to Change the Regulation Regarding Manufacture of Glass. Grinding. Etching. Painting. Glass Containers and Related Industries, Dated September 13. 1940. Anonymous. Arbeitsschutz. y. 263 (1940). (German). The German regulations prescribe that x-ray examinations be made of all mrkers employed at certain jobs in rooms where glass containers or refractory materials are produced or where sandblasting is conducted. The examinations are ropeated every second year. All persons engaged in producing lead-containing mixtures or using lead colors are to be examined at least every 6 months. 03118039 t i i !
