[TheForge] Ice rink

[Suddenlink]

FWIW. I thought All that was interesting.  & it applies to some of our shops. The ice rink disaster was caused by a refrigerant leak which displaced O2. I have a recurring problem w my inert gas regulators leaking small amts of gas where reg connects to tank. Not a danger for me as leaks r small & shop is large @ drafty. But in a close/tight space would/could be dangerous. We all think abt fuel gas & O2 leaks as dangerous (& they r) but other gasses displace O2.  Just as hazardous 2 u r health.
