the present work concerns the determination of the charge in single spark discharges from selected textile fabrics and the incendiary behavior of such sparks in the presence of stoichiometric mixtures of natural gas and air and hydrogen and air. the results have shown that under certain conditions sparks from a polyester and a cotton fabric are large enough to ignite each of these gas mixtures. ignition tests with negatively charged fabrics have shown that sparks with charges in the region of 0. 1 $mu$ c can ignite the natural gas-air mixture. the corresponding charge for the ignition of the hydrogen-air mixture is in the region of 0. 02 $mu$ c. spark discharges from negatively charged surfaces are considerably shorter in duration and larger in magnitude than are sparks from positively charged surfaces. 9 refs
