Digest of Industrial Sygiene - 25. 518 Comers* Stripes -- The Coal Miners* Dermatosis. F.3. Bettley. Brit. J. Der matol., "32, 129 tApril, 1940). Colliers' stripes appear on exposed parts as numerous linoar end irregularly shaped marks? the result of an accidental tattooing of coal dust Into the skin. It has been claimed that those wounds rarely suppurate and that the particles of coal do not excite any roaotlon in the tissues. This author's observations dis agree with those claims. Suppuration 00010*3 no less than is to he expected, and histologically ha has found a foreign body reaction, particularly near blood vossols. 519 Skin Troubles and Machine Toole. A. Dunkham. Engineer (London) 169. 501.2 (Hay 31, 1940); Machinery (toadon) 56, 188-9 (Hay 9, 1940). The author's experience with oil dermatitis began nearly 40 years ago, whan the bacterial origin theory was considered sufficient. In the light of additional knowledge, bacterial contamination is considered a factor, but not the main faotor. The author attributes tho disease primarily to tho stoppage of the skin poros by oil containing motal dust and other dirt, interfering with tho natural discharge of perspiration. Loss of tho natural grease of the skin la also a fee tor. Inflammation Is followed by suppuration and In that stage the disease Is Infeotivo. The preventive measures suggested Include protection by an oil-resisting ointment (or water-realsting when emulsions are used), use of. lanolin tc restore grease to the skin, and general cleanliness of machine and cooling oils, 320 Industrie! Dermatitis. D.C. Straus. Nat. Safety Nevis, 43, 36, 82 (January, 1941 In Illinois, during the first two years of operation of the Occupational Disease Act of 1936, 107 claims out of- a total of 474, or 22.591 were for occupational skin diseases. In 1939 the ratio had risen to S9.39&* which was a higher percent age then for any other type of occupational disease. A similar increase ban occurred In 5 other states. Among dishwashers, one of tho larger groups most subject to dermatitis, and among bottle scalers, sodlun hsxaaetophosphate applii to the hands and dried boforo working, proved completely successful In combating dermatitis from washing compounds containing chlorine. In tanneries, sodla hyposulfite has boon found very effective aa a preventive. "Chaaieal gloves" o: akin coatings Insoluble in tho solvents being bandied are of two types, watersoluble and wntorpxoof. The first type gives good protection against paint, lacquers, vanishes, oils, greases, waxes, thlmors, carbon black, lead oxides, carbon paper, otc. Tho second typo la used for protection against cutting com pounds and cooling lubricants In which tho wator content exceods 10$, and with strong acid and alkaline solutions. 521 Prevention of 0^ Dermatitis.

Tho belief has developed, and Is accepted today, that in the prevention of der matitis the aphasia must bo put not on cleanslog the oil but on cleansing the worker. Experiments have shown that by regular and vigorous attention to xbov lng tho residua of oil and dirt from the skin after each exposure, long strides will have boen made toward the prevention of dermatitis.
