plant components which can be hazardous
to individuals unfamiliar with such
equipment. It is the user’s responsibility to
permit only trained and qualified process
plant operators familiar with the handling
of compressed gases to operate this
equipment.
Breathing
This unit is designed to produce 95-99%
pure nitrogen. Nitrogen is a colorless,
odorless gas that will not support life. If
released in an unventilated area, it will
displace the oxygen and can cause injury
or death from asphyxiation. A general
indication of what can potentially occur at
depleted levels of oxygen is given below:

12-14%: Respiration increases with exertion,
pulse rate increases, coordination
is impaired, and perception and
judgment are also affected.
