USA Liquid Oxygen Cylinder Explosion

Accident Profile

Two individuals (ages 42 and 60) found a liquid oxygen cylinder that had been removed from service and left at a scrap metal dealer
The individuals were self-employed in scrap metal cutting operations and intended to use the cylinder in their work
The individuals had access to a liquid oxygen supplier where cylinder ownership would not be questioned

The PRD was removed and plugged
The cylinder was filled while onboard a pickup truck
The cylinder, which had no vacuum, was now unable to vent excess pressure
While the cylinder was being transported down a busy highway, the pickup truck experienced a flat tire
Shortly thereafter, the cylinder exploded with the results shown in the following slides:
