Will You Be Here Tomorrow?

Work safety video with a dark depiction of the industrial workplace due to the Tom Savini-esque gore slapped on it's face like make-up on a cheap whore. Rhyming prose there, you don't see that every day. The best one is the guy blow torching that metal barrel - for the love of God why? What possible circumstances would arise where you would need to blowtorch a barrel?
The only reason to blowtorch a barrel is if the barrel has a hole in it and consequently can no longer be used for its containment purposes. That then beggars the question, if it had a hole in it then all the liquid/substances would have poured out anyway so why fix it? Ergo a new barrel of the liquid/substance must be ordered again and as that same said liquid/substance ships in a containment device (barrel) no blow torching is required on the old barrel. It has been replaced by the new barrel. It's usefulness within the work environment has expired much like the worker who is trying to fix it and therefore it must be discarded. Even if you refuted these arguments and really had a hard-on for mending barrels then surely you wouldn't bring an instrument that produces flame anywhere near a barrel that could be flammable?
However instead of using common logic, this gaping asshole blowtorches the barrel creating an immense explosion probably killing every worker in the entire factory.
Be careful out there.
Thanks Nick ;)
