If the nitrogen or argon vessels came back in with product I used to hook a metal hose to the dip-tubed liguid outlet and used it to "sweep" the dock. Gaseous N2 blew the dust into the air and then right back down. The liquid would adsorb (not a typo) the dust and then roll right off of the dock leaving it clean as a whistle.
One guy actually froze a dirty little rat in liquid O2 and then threw him against a cinder block wall. Blew an approx. 10" x 10" hole through it. As we all know, mixing O2 with hydrocarbons is NOT a good idea.
Ahhh ..... those were the days.
I knew you had potential for bigger and better boomage !
Freep mail !
We had a fatality involving nitrogen - we had two different types of N2 on the line - lopack (low pressure) and hipack (high pressure). He forced an adapter on to the hipack system, and tried to air up the nosewheel on an F-16. That much pressure in that small a space resulted in an explosive failure of the tire and wheel. When you're a foot away from something like that - it tends to do a lot of damage.
As far as O2, they showed us a video of what happens when you use greasy tools with O2 - they called the result "Pizza Man."
LOL on the rat!!
