Processes
One of Nitrogen’s most useful properties
is its
chemical inertness to
nearly all substances at ambient and
moderate temperatures, making it a key
gas in:
Inerting,
blanketing or padding
– pure or in mixtures, as a
protective atmosphere
against
oxidation or combustion
by atmospheric air and contamination by
moisture.
Purging
– to
displace or dilute
unwanted gas or vapour, to reduce oxygen
concentration or remove air, flammable
or toxic vapour.
Flushing
– to flush unwanted gases from
solutions, due to its only slight
solubility in a wide range of liquids.
Heat
treatment
– as a
protective
furnace
atmosphere for heat
treatment of the most reactive metals.
Food packaging –
in mixture with carbon dioxide and
oxygen in modified atmosphere packaging
(MAP); pure to reduce oxygen
concentration in respiring food products
packaging.

Information
Nitrogen is not toxic and non-reactive
except at high temperatures.
If
insufficient oxygen is present, high
nitrogen concentrations cause
asphyxiation and death. They are no
physiological warning signs to nitrogen
enrichment.
Nitrogen does not support combustion.
Liquid
nitrogen has the capacity to inflict
dangerous frost bites.
See Safety Data Sheet for further
information.
