Pittsburgh, Pa.Cleveland, OhioCincinnati, Ohio.Columbus, Ohio.'“

.All’ ordinary preca.utlons required for t'Jie safe operation ofany electrical equipment should be observed in every radio sta-tion; for example, all high-voltage wiring Sxbould be carefullyinsulated and kept as far as possible from other wiring and soplaced as to minimize the possibility that persons may come incontact with it, and suitable danger tags should be displayed.'

Insurance companies and city governments make certain re-quirements regarding electrical installations in buildings. Theusual requirements are summarized in a small book, the NationalElectrical Code, which may be secured for five cents from theNational Board of Fire Underwriters, ^5 John Street, New York,N.Y. Article SlO of this Code gives the requirements for radioequipment.

Requirements for safe radio construction are given in Na-tional Bureau of Standards Handbook H9, "Safety Rules for RadioInstallations, " ¥/hich may be obtained from t'ne Superintendent ofDocuments, Covernment Printing Office, Washington, D.C., at tencents per copy. This 'handbook ycives
