Abstract:

Under this project, magnesium chip fire tests are outlined in the Standard for Safety for Rating and Fire Testing of Fire Extinguishers, ANSI/UL 711, were conducted to evaluate the fire fighting effectiveness on this combustible metal using liquid fire suppression agents, identified by NIST as biodegradable, environmentally safe, and nontoxic, when applied using hand hoselines. For comparison purposes, fire tests were also conducted using water only and a UL Listed Class D dry powder agent. Only the UL Listed Class D dry powder agent demonstrated compliance with the fire extinguisher criteria outlined in ANSI/UL711.
