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.
