A Costly Lesson in Gas Safety
In June 2023, a boiler commissioning job in Bundaberg, Queensland, ended in disaster.
During an LPG purge inside an enclosed boiler room, gas was vented into the workspace instead of outside. A fixed gas detector eventually sounded the alarm—but moments later, a worker lit an oxy-acetylene torch. The resulting explosion engulfed four workers in flames and led to $131,000 in fines for serious WHS breaches.
This tragedy highlights a simple truth: having a detector isn’t enough—it must be integrated into a complete safety system.
