Corrosion Induced Explosion of a High-Pressure Fire-Extinguishing Gas Cylinder

Thanks to Mr Satya Subrahmanyam DGM, EHS, Coromandel International Limited, for sending a link to the article Corrosion Induced Explosion of a High-Pressure Fire-Extinguishing Gas Cylinder in the Journal of Failure Analysis and Prevention -October 2014, Volume 14,Issue 5,pp 564–568 by Yong Jiang,Jian-ming Gong,Peng-jie Tang.
 The abstract of the article mentions "The failure of a high-pressure fire-extinguishing cylinder was investigated. Failure was induced by internal surface corrosion and stress corrosion cracking (SCC) due to condensation of carbonic acid. In internal surface, especially the area near the bottom of the exploded cylinder, severe corrosion was characterized by local pits. SCC initiated from these local corrosion pits was observed by metallurgical analysis. Microstructure of the failure cylinder near the internal surface consisted of multiple-banded structure and the banded structure could accelerate local corrosion initiation and propagation. The corrosion products built up on the fracture surface were primarily ferrous carbonate (FeCO₃). The determination of moisture in fire-extinguishing gas was also examined."
Be careful of your CO2 extinguishers. Traces of moisture which can get in during refilling can cause the formation of carbonic acid and cause corrosion.

Inadvertent mixing incident causes chlorine cloud

More than 100 people were treated for respiratory problems after an inadvertent mixing of chemicals caused a large gas cloud at a plant in Kansas, USA. The two chemicals involved in the spill were identified as sulfuric acid and sodium hypochlorite, which mixed to create a chlorine cloud.
Are you training personnel on the inadvertent effects of mixing of chemicals?
