Oxygen cylinders
Volume, thank you for your reply.
I read earlier in the thread about oxygen cylinders and explosions.
First, I gather that any reference to those are speculation at any level, even if the fire was close in proximity.
100% oxygen will cause just about any material to become flammable, even steel.
That, however, would require a massive leak (or rupture) AND a source of ignition for it to be the sole cause.
Looking at the second video it seemed like a relatively small fire getting out of control, which indicates to me that the oxygen cylinders are likely not the root cause, but if pressurized supply lines are breached as a result of the fire the situation could for that reason have accelerated rather quickly.
