Bulletin on Static Electricity Issued
Sparks caused by charges of static electricity constitute a fire and explosion hazard in a wide variety of industries, according to the Department of Commerce.
Circular C438, just released by the National Bureau of Standards, describes, partly in non-technical language, the nature and origin of such static charges.
The purpose of the circular is to give a general outline of the various ways in which manifestations of static electricity introduce appreciable hazards into many industries, and to present, in convenient form, a quantitative basis on which engineers can develop such safety measures as may be required. Various methods used for mitigating the hazard are listed and the possibilities and limitations of these methods discussed.
Copies of Circular C438 may be obtained from the Superintendent of Documents, Washington, D. C., at ten cents each.
