Analyzing Fire Extinguisher Failures

B. W. Christ / J. H. Smith / C. H. Brady

Hydrostatic pressure testing and metallographic examination was carried out on stainless steel inverting type fire extinguishers to determine the cause of failures by circumferential tearing at the dome end of the extinguishers. Intergranular cracking of sensitized metal, perhaps over a period of 15-20 years, seemed to be the cause of these failures.
