When you work in the oil and gas business, particularly if you’re around live plant or involved in construction, safety is dinned into you with all the subtlety of Trump running commentary on the Mueller investigation. It’s so effective that when you wander outside the oil and gas environment you wonder why people are deliberately trying to lose an eye or commit suicide. The industry takes safety seriously because 1) hydrocarbons are phenomenally dangerous and 2) unlike other industries, they have plenty of money.
One of the things people involved in maintenance understand is the importance of purging vessels. If you need to do some work on a tank, separator, or drum that normally holds hydrocarbons you first empty it, then you purge it with nitrogen. Then when you open it you use an ultra-sensitive gas detector to make sure there’s nothing poisonous, flammable, or explosive left inside. I don’t know where the following video is from other than it’s Chinese and I’m not entirely sure what happened, but my guess is whatever he was doing ignited residual gas in the vessel.
