Based on the news reports, it sounds like they were mixing H2 and O2 together in a cylinder. This can be very dangerous if not done properly. Gas companies have very strict procedures on Fuel/oxidizer mixtures. Tragically explosive gas mixtures have been the cause of numerous fatal accidents worldwide. The U of Hawaii accident while not fatal caused significant damage and injury. See my article

As this is no longer available on the SGR website, you can download from my website under files.
I have a detailed article that is 50% done on 40 years of industry experience with explosive gas mixtures and how to dispose of one. This is based on my investigations or information shared with me by companies on their incidents. I hope to finish this soon

Subject: [DCHAS-L] Recent Fatality
Dear safety team,
I would like to share a very recent safety incident that happened yesterday in my previous institute, Indian Institute of Science (IISc). We are striving for strict safety adherence to our institutes. This incident shows how important is safety for a workplace.
A gas cylinder is blasted with a huge sound! The accident happened while creating a shockwave as a part of an ongoing research project. One person was dead instantaneously and 3 are critically injured. The four were employees of Super-Wave Technology Pvt Ltd (SWTPL), an IISc-incubated startup headed by senior scientists at the department of aerospace engineering, IISc. More details are under investigation.
