Why is the nitrogen we breathe in not absorbed by the blood vessels?

The Nitrogen we breathe IS absorbed by the blood vessels (and all the body tissues). While the Nitrogen gas from the air is inert and does not play any part in body processes, Henry's gas laws require that some of the Nitrogen will be absorbed/dissolve in the blood (and body tissues). This becomes an issue for sub aqua divers where the presence of this dissolved nitrogen causes the "bends".

Can nitrogen be used to purge gas pipes before welding?

Yes, and No, Nitrogen can be used to purge gas lines prior to welding, but the correct answer depends on several things, mainly, your welding application. A significant amount of resistance welding applications use N2 as a suitable environment for welding. Other applications use N2 as a purge gas, and then purge the N2 with the process gas. That said, if you were going to be using a different inert gas (Argon, Helium, Xenon, etc.) to provide the actual the actual shield for the weld, then you would still need to displace (purge) the N2 from the lines. The last statement leads to the question of; if you are going to have to purge the lines anyway, why do it twice? The answer to this question is pretty basic. Nitrogen is cheap. If you had to purge a lot of lines, or a large volume of space, you would rather use N2 to drive out the Oxygen and lower the dew point (moisture). Using one of the other welding gases would cost about ten times as much to perform the operation.


What must you do before you introduce nitrogen into a refrigeration system?

If you are going to purge the system using nitrogen, rather than evacuating the system with a vacuum pump, you will first need to remove the refrigerant gas without releasing it to the atmosphere.


What is the precautions are taken in nitrogen?

Precautions: - When opening nitrogen cylinders or pipelines lines, insure that you are in a well ventilated space. Bleed off pressure slowly. A confined space with nitrogen present is a killer. - Avoid directly breathing nitrogen, when using it. A respirator will not save you if the percentage of nitrogen in the atmosphere increases to 90%, displacing oxygen down to around 11%. Only a self-contained breathing apparatus can be used in this type of atmosphere. The results of overexposure to nitrogen can be sudden and immediate. If oxygen the level fall below 18%, seek a safe environment immediately. - If a co-worker has been overcome with nitrogen in a confined space, DO NOT rush in unprotected to try to rescue. Immediately call 911, then put on an SCBA, to attempt rescue of the person. - Always test confined space atmospheres and continuously monitor it if compressed nitrogen gas is being used in that atmosphere for purging. - NEVER open a vessel that is under a nitrogen purge to look into it, without first having a SCBA on and operating. The effects of nitrogen poisoning to the body is immediate, and workers have been known to lose consciousness and fall into vessels that were open under a nitrogen purge. - Shut off all cylinders and nitrogen supply tanks when finished with use. Properly secure cylinders and tanks to a non-moveable structure. All empty and full containers should be labeled.
