Commercial gas cylinders are common type of pressure vessels in many health care and technical facilities. Unexpected
failures of gas cylinders occur despite of fact that the design, manufacture route, quality control, transportation, and handling
are specified by various standards and regulations, particularly in domain of periodic inspection. A case study of the sudden
failure of the 25 years old gas cylinder made of low-alloy steel is presented in this paper. Exploded cylinder was filled with
commercial mixture of nitrogen and CO/CO2. Results of chemical analysis, mechanical testing and microstructure and
fracture surface examination of gas cylinder material are given in this paper. Key results from failure analysis revealed micro
corrosion pitting as a consequence of undesired traces of moisture. This slow crack initiation combined with gas mixture
filling and exhausting cycles, promoted the local damage which could explain the mechanism of failure. In addition, the
analysi...s of gas cylinder material in moment of failure is evaluated by using the critical distance parameter
