Don’t run for cover!


Today’s post is about Nitrogen Refrigerated Liquid.


What, exactly, is Nitrogen Refrigerated Liquid you might ask?

When it is in the “Free State” it is 75%, more or less, of the air we breathe.

When it is in “Liquid State” it is about -278 degrees Celsius.

What is this scary Nitrogen stuff used in?

It is used in the welding process of steel, plastics, and other exotic materials. It is also used to make micro chips. It’s best known use, by you, is probably when the doctor “burns” off a wart. The nurse brings a thermos jug, of sorts, into your examination room and the doctor carefully removes the lid. A long wooden stick Q-Tip is inserted into the flask by the doctor. When withdrawn the stick is smoking. He then presses the tip on your wart. Your reaction is to immediately say “Wow, that burns”!

What the process actually is is freezing the non standard tissue, I.e. your wart, and probably some of the good tissue around the bad area. The good tissue will regenerate and voila the bad tissue is gone.

The reason for the wooden Q-Tip is the -278 degree Celsius temperature of the liquid will damage the “elasticity” of other materials to the point they instantly fracture when stressed.

Do you remember when Mr. Wizard bounced a rubber ball on the floor and then, with his heavily gloved hand, carefully slid the ball into the bowl of this steaming liquid? He used tongs to remove the ball after the boiling around it had ceased. Then he dropped the ball on the floor. The result was the ball shattering into a gazillion pieces.

Nitrogen Refrigerated Liquid has many uses. One other medical use is in microscopic examination of tissue samples. Biopsies for example.

The lump, bump, growth, mole, or other questionable piece of you that needs in depth examination will be sent to a lab where the sample can be immersed in the liquid and then pieces will be shaved for microscopic examination.

There are probably tons of uses for this liquid gas but Joe and I can’t come up with more.

Strict safety measures are demanded in the transport of this product.

Orange cones are placed at the front and rear of the parked vehicle.



The cones are to alert others driving near the tanker of the possible dangers involved in an accident.

Wheel Chocks are placed between the rear axles of the truck to stop it from rolling away while unattended.


I have posted about the “Day Cabs” we have driven. This is one of the trucking industries uses for day cabs.


Now that wasn’t a bad lesson in trucking today, was it? 😀
