Lab safety rules have on a regular basis stopped incidents from occurring in the first place, but this is the first time something unexpected happened and bad things were averted by a safety precaution.
That's a hell of a lesson. I'm glad it happened the (relatively) easy way. It kinda makes me wonder what percentage of safety precautions like this are in place because someone thought long and hard about it, and what percentage are in place as a reaction to an incident.
You know those Freeze Off wart removers? The instructions warn against using them on or in your genitals or anus. I sincerely hope this was one of those "thought long and hard about" instances.
One liquid nitrogen rule that I know is in place as a reaction to an accident (basically because before this no-one thought anyone would be stupid enough to need this spelled out) is "don't replace both the main and backup pressure relief systems on a liquid nitrogen cylinder with metal plugs". Full story here
. Fairly miraculously no-one was killed or injured in that one.
The most general safety rules, and the most important, are 1) always understand what you are doing and how it can go wrong 2) treat dangerous things with an appropriate degree of respect: high pressure deserves respect, extremes of temperature deserve respect, oxidisers deserve respect, lasers deserve respect, ultracentrifuges deserve respect etc. etc. because if they don't get treated with respect they have a tendency to do bad things to people.
P.S. I highly recommend both the "how not to do it" series, and the "things I won't work with" series from the blog in the link.
That was an amazing Read.
When things go Wrong it is so very interesting.
Can you imagine?
What was it like to walk into that room?
How can one small tank hold so much energy?
No. Don't tell me. It's the same old Story.
Phase shifts are a powerful force.
That is what the Atomic Bomb is, sort of.
Back on Topic.
It is a Rare Rule that does not follow Tragedy of some kind.
I was in an automobile accident.
After our Crash, a sign was put on that piece of roadway.
In the mountains, 90 degree turns seem to come out of NoWhere.
After someone screws it up.
A sign is installed.
Do we, really, have to tell people, "Hot! Do not pour onto your genatals."
Yes. Yes, we do. Folks don't get out of bed thinking, "I'm going to stick my hand in sulphuic acid."
Like coffee on genatals, this stuff happens because we don't think it can.
Not to us. We brushed our teeth, stopped at the red light, called mom and got to work on time.
Not to us. We are good people doing good things.
Shit can happen to us, too.
Each warning sign is a memorial to those gone before.
Look at what Some Idiot smart enough to be here did!
These signs are Great!
Did I ever tell you about the guy that wanted to Protest the Dangerous Materal Sheets for Water?
He said we should all know.
Know about Water?
Water is so dangerous in a Lab.
By Law we must have reminders.
Water over There---->

Life is, just, an exchange of electrons; It is up to us to give it meaning.
