SOME DATA RELATIVE TO THE CONDUCTIVITY OF FIRE STREAMS

Issue 10 and Volume 87.

SOME DATA RELATIVE TO THE CONDUCTIVITY OF FIRE STREAMS Resistances of Varying Stream Lengths and Pressures, Directed Onto Lines of Different Voltages As requests for information as to the conductivity of fire streams haze been received from time to time, the following extracts from the book, “What Every Fire Fighter Should Know” compiled a few years back by the Editor of FIRE ENGINEERING, are reproduced to answer such queries: QUITE thorough and enlightening figures on the conducting qualities of fire streams is presented in data of experiments by Messrs. Allan Bond and O. G. Galland at the Ohio State University. In order to determine definitely what hazards, if any, exist for firemen when they are compelled, in line of duty, to play water from fire streams on live wires at various potentials, arrangements were made so that circuits of 525, 2,300 and 4,600 volts, respectively, were available. One side of…
