CO <; -- -S'. Digest of Industrial Hygiene - 23. 506 Handling Paint Products. Anonymous. Hat. Safety News, 43, HO-1, 76 (Hay, 1941) This is a brief paper presented In popular style, dealing with conposltlon of paint and the hazards involved in its use, including lead poisoning and fire ai health risks from the thinner. The precautions recommended lncludo use of non* inflammable solvents, wearing of respirators and gloves or use of protective creams or liquids, use of raw linseed oil for removing point from the hands, washing boforo eating and opening out doths3 or rags saturatod with oils to avoid spontaneous combustion which occurs when rags arc closely stored. 507 Treetmont of Chronic Benzene Poisoning in Low-Pressure Workora with Ascorbic Acid. 7. Hagen. Arch.Gowarbcpath. u. Cewsrbehyg., 9, 698-904 (l939), (German). Increased lyophoeytos and decreased rod colls and hemoglobin were noted in ben zene poisoning. The urinary level of ascorbic acid diminished* Ascorbic acid in doses of 75-105 mg. daily for 6 to 7 weeks resulted in return to normal vali 508 Cornenv. Circular of the Minister of Labor Concerning tha Use of Benzene. August 20. 1940. Arbeitsschutz. pp. 236*7 (1940). (Gorman). Tho danger of benzene poisoning in Germany has increased on aocount of its sub stitution for benzine, which Is difficult, to obtain. The following regulation! aro announced: (1) avoiding the use of benzene in dosed spaces; (2) replace ment by tolueno and xylene when possible; (3) materials containing over 835 ben zene must be especially labded; (4) hours of work for woman and young men sms' bo roduced, and pregnant women must not work with benzene, end (5) all persons using such solutions must be examined every 4 months. 509 The Danger of Continued Inhalation of Oxygen or Carbogen During Acuta Polsonln with Chlorinated Solvents. D. Matrucbot. Bar. 8 intern. Kongr. Onfallmed. u. Berufskronkh. 2, 913, (1939); Zentrv Qewerbehyg. Unfallverhnt, 27, 27 (1940) (Geman). Three guinea pigs which had been kept 9 minutes in en atmosphere of 150 mg. ' trichlorothylene per liter wore in deep narcods, although the respiratory rat was 50-60. Tho animals were lisaediately placed in a gas chamber in which tho atmosphere was brought to 60)5 oxygen or oarbogen in tho course of 3/4 hour. Up administration of theso gases the excretion of trichlorothylene during tho fir minute was moro rapid than In air, hut later became slower. After trlehloretb lene poisoning, therefore, the animals recover much more slowly In oxygen end carbogen. 510 Solvent Decreasing and Hedth. N.E. Promisel. -Products Finishing. 5, 48-57 (February,194l), T.ichlorethylone Is the advent most generally used in degreasing, and its pre parties ore discussed with roforenoo to hazards. In tha proper method of mane facturo it is thoroughly purified and stabilizers ore added to prevent its de composition under mast of the conditions of handling. The stabilization does not proven* decomposition due to contact with flames or rod hot surfaces, and should not be used within 50 feet of sources of heat. Tho design of several types of dogroasers is next discussed, with illustrations and a diagram. The qulrcments of the New York Division of Industrial Hygiene for exhaust systems aro included. There aro no health hazards in solvent degreasing if tho unit : properly designed, Installed and operated. 511 Action of Carbon Tetrachloride on the Circulation. B.A. Oelkors and H. Fiedli Arch, exptl. Path. Phaxmakol. 195. 117-20 (1940}`. (German). In rabbits and cats anesthetized with urethan tho inhalation of carbon tetra chloride vapor caused an Immediate drop in arterial blood pressure. i
