Since moving to Dallas, I’ve seen two or three nitrogen tanks in the median of streets connected to some box. Below is a picture of the one near my house. I mentioned it on Facebook a few weeks ago, and today my brother said he saw one in Tyler where he lives. I don’t recall ever seeing any until a few months ago. What is their purpose?
Underground wire/cable maintenance, most likely: Google Answers: Liquid nitrogen into sewers - why?
Interesting. How long do they typically get left there?
Morbid soul that I am, my immediate thought was - has anyone ever run into one in a traffic accident? Anything happen?
umm… ever seen Terminator 2?
Only a T-1000. But not for long…
