Testing update on protective clothing and equipment for electric arc exposure

Abstract

This paper includes an update on testing to characterize electric arcs and the performance of flame resistant clothing, first reported on at the 1996 Petroleum Chemical Industry Conference. The goal of this work is to assist electrical personnel in selecting appropriate arc protective clothing and equipment based on readily available electrical system parameters and the task to be performed. Updated protective clothing guidelines and detailed testing results on cotton ignitability and para- and meta-aramid protective clothing systems are included. Results of additional three-phase arc testing at 600 V, including acoustic measurements, are discussed, as well as results of separate testing performed on polycarbonate face shields/hoods and leather work gloves.
