Tlie chief uses of the apparatus so far have been, to maintain respiration in thuno individuals ivlio because of siraic disease or other renditions hn.ve had the muscles of respiration paralyzed. The cost of this respira.lnr is $2000, and most of thu prin eipal large eities iiave }irovided a number of these for use in different hospitals. TotntNiQOFrrs Q. -What is the present viewpoint on the use of tourniquets to control bleeding? A. W. B. A. - -Tourniquets are still used by a con siderable number of lirst-aid instructors, especially in controlling hemorrhage from large arteries. There is a giorving couvic tion on the part of many first, aid authori ties that most bleeding, especially from smaller blood vessels, can more easily be controlled by digital pressure. In this method, there is also not the danger of preventing the circulation of blood, which may lead to severe difficulty, finally, in the production of gangrene. The Council lias a recent poster on this subject, No. 198`1-B, sample copy of which will be sent for the asking. WEIGHT LIFTING Q. Are there any standards of weight lifting in different states?- (1. I,. A... -The following states have made regulations as noted, (applying to women only) relative to the lifting of certain weights of material: (lalifornia, 75 pounds: Ohio, 25 pounds; Pennsylvania, 15 pounds; New York, 25 pounds. In each ease Die maximum number of pounds is slated. Ah far as wo know, (here are no similar regulations applicable to male employees. The problems of weight lifting are rath er complicated ami we shall bo glad to discuss them with you iir correspondence. The Council has a very good pouter on the proper way l;o lift: weights, snmplos of which can be obtained for the asking. COM PENSATION COSTS Q. What, is the e.ost of compensntinu for occupational disease?- -!j. A. B. A.- It is difficult to get national figures for the cost of occupational diseases, be cause of the great variation in the various laws of different, states. In the State of Wisconsin, where complete coverage has boon in effect for a period of year.!, com parisons have shown that the cost of oc cupational disease coverage is approxi mately one per rent of the total amourpaid out in tin:,-: state for industrial in juries. An idea, of the coat of occupational, dm eases in the States of California, Wiscon sin, Massachusetts, Connecticut, North Jtakot-a, and Maryland, may be obtained, by referring to the reports of the .Industrial Commissions of these states. EXAMINATION FOHM Q.--Where can I get a good record form for physical examinations in industry?- A. J. K. A.--In our Health Practices Pamphlet No. 2 on "Physical Examinations in i n dustry," is to be found a composite form for physical examination work. This form is the result of the study of hundreds of individual forms used by different - s trios. The form is made especially elastic, so that spaces may be loft blank, or that other items may be inserted, according to tho wishes of the physician whu uses tirform. Hamplu copies of Health Piac-iices Tnmphlot No. 2 may tie obtained by addressing the Industrial Health Division of tinCouncil. M10A B'OTT <$.-- We use a great, deal of powdered mica in our planc; is this injurious! to tie lungs t--IL L. li, A.-- The expression "injurious to the lungs" when used with reference to the effects of rariocs dusts, is construed to moan causing- a librous tissue reaction im tho normal Jung structure. At the pmwni time there are cnly certain dusts known to cause this inj.trious effect, these belay free silica dust, i.sbestos dust, and earborundum dust. Chemically, mien is a very complicated compound, essentially composed of the sili cates of aluminum and other alkalies, such as potassium, sodium, and lithium. Mien is, therefore, an example of the combined silicates, such as clay, tale and feldspar. The only known combined silicates that produce libi-osie fro those two mentioned above, namely, asbestos, and carborundum. NBBN1A. (.---(a) Wha1; percentage of herniiu. are thought to be "nseidontal" i (b) Who ac cepts the responsibility for industrial hernia?....W, W. A.-- The exact percentage of industrial hernias classed as "accidental," is not known. Most authorities agree that only a vory small number (pre:mmably lees time 10 per cent) arc thought to bo industrial or accidental in irigin, In general, the employer always iivciqiU tho responsibility for industrial hernii:, s! though this may vary In any given case. Some states ha'-o specific provisions in their compensation laws relative to heruiu, while in others hrii-ni.ti te considered :m in dustrial injury and comes under the genoral interpretation of the provisions for compensation for industrial injuries., i n formation can be given by letter relative to any particular state in which you hew an interest.
