10/28/25 UPDATE: Hydrogen (H2) FATAL Line Break
RIP
ππππ© πππ₯π₯ππ£ππ?
The two deceased workers, identified as Mr K (43) and Mr A (50s), were subcontractors conducting scheduled maintenance on a hydrogen pipeline. The task involved inserting a blocking plate into a pipeline to isolate flow, a process requiring the loosening of flange bolts. The explosion is believed to have occurred during this step, when hydrogen that remained in the pipeline escaped and ignited.

Authorities believe the pipeline was not fully purged of hydrogen before it was opened, a standard safety step that typically includes:
– Flushing the line with inert gas to displace Hβ
– Conducting a residual-gas inspection before unsealing
Itβs currently unclear whether purging procedures were performed as required, and also what ignited the hydrogen. Possibilities include static discharge, high-velocity leaks creating friction or heating, or contact with hot surfaces. Tools used during the task are being tested to determine if they are explosion-proof.

– Police investigations and safety audits are still underway

10/23/25 UPDATE: RIP Two (2) of the four workers have passed. Criminal charges may be brought against the company executives.
Four (4) contractors have been seriously injured after a hydrogen pipe exploded and caught fire at an oil refinery. The incident happened at the hydrogen production facility, which produces grey H2 from steam methane reforming. The methane-cracking facility had been undergoing scheduled maintenance work, and the facility believes that the fire started when a pipeline that was thought to be empty but actually still contained hydrogen was opened by contractors
Four contractors were said to be seriously injured with second-degree burns and were being treated for burns at a specialist hospital unit, while a fifth sub-contractor suffered minor injuries.
