NITROGEN BUY

Nitrogen gas is a colourless, odourless and tasteless gas that makes up ca 78 % of the Earth’s atmosphere. It does not support combustion & is non-flammable so it is used in certain “blanketing” or ignition prevention applications and for this reason is an asphyxiant.

As a result, it is often thought as being an inert gas but it is not truly inert.

For instance, Nitrogen forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur. Also Nitrogen compounds are formed naturally through biological activity.

Nitrogen is NOT an inert gas andis slightly lighter than air having a density 1.19 kg/m3 (i.e. 0.99 relative to the density of air at sea level atmospheric conditions) and slightly soluble in water.

It is widely used in many applications as it is cheap and readily available as a by product of the air separation process for producing Oxygen from air. As a result of this manufacturing process, Nitrogen is also food safe with a corresponding level of  certification.

Hazards

The single greatest risk to workers using Nitrogen gas is asphyxiation when carrying out large tank purging or working in confined spaces which have been previously purged.

With Cryogenic liquid Nitrgogen there is a very significant danger of workers involved when still cold weather conditions as and liquid Nitrogen that escapes forms large localised concentrations of gaseous Nitrogen and asphyxiation under these cases is rapid with the individual(s) becoming unconscious & if not rescued by Emergency Workers wearing Air Breathing apparatus then death follows if the Nitrogen gas has not dissipated.

There have been cases of fellow workers nearby (Without Air Breathing apparatus.) going to the scene to provide assistance also loosing consciences and sadly dying.

As mentioned in the Overview above, it forms 78% of the air we breathe so if used in a well ventilated area it is safe to use as it is non-toxic and non-flammable.
