Section III - Safety
CAUTION!
Nitrogen is an asphyxiant. Before
entering an enclosed or poorly
ventilated area containing nitrogen
generation or transmission equipment
and piping, follow all established
safety precautions and procedures.
Nitrogen gas represents an extreme
asphyxiation hazard when not handled
properly. Product gas should not be vented
or otherwise discharged except through the
normal piping system. Appropriate signs
should be placed in the area of the nitrogen
system warning of the hazards.
Combustion
The waste gas (permeate) vented out of
the system is oxygen enriched; it typically
contains 35%-40% oxygen, but can be as
high as 45% oxygen. While oxygen will not
burn, oxygen concentrations above 25%
will support combustion of other materials
much more readily than air. For example,
materials that smolder in air could burn
fiercely in the presence of oxygen-rich
air. It is imperative that vented gas be
discharged only in safe, well-ventilated
areas. If the unit is located in a poorly
ventilated room, the waste gas must
be piped to a ventilated atmosphere for
release.
Pressure
The feed air pressure supplied to the
generator can be as high as 200 psig.
The nitrogen product is then delivered
to the user’s system at a pressure within
10-20 psig of inlet pressure. Normal
precautions for pressurized systems
should be observed during operation,
service, or troubleshooting. Always isolate
components that are to be serviced,
venting pressure before disconnecting lines
or dismantling components.
Electrical
The DEFENDER™ is 100% pneumatic and
does not have electric operations. (The
built-in N2 analyzer uses a replaceable 9
volt battery).
Environmental
The automatic drains for the entire
system are connected to a single header.
These drains release collected oil and
water. Because the condensate from this
equipment contains oil, it must be disposed
of properly.
