2 Precautions and safety instructions for nitrogen generators
General safety standards
When working with the nitrogen generator of FX Prevent, there are some safety risks that have to be considered. The risks
involve subjects such as dangerous voltage, high pressure and dangerous gas to inhale. This is addressed in this chapter. It is
highly recommended that the safety risks are observed before work on the devices is commenced.
Working with the nitrogen generator
The nitrogen generator is commonly located in the technical room of the facility. When operating or when working on the
nitrogen generator, the following hazards should be considered.
Symbool Omschrijving Geldt voor
HIGH PRESSURE, Relief
pressure from components
before work is conducted. The external components of the nitrogen generator which are:
•
Valves;
•
Hoses;
•
PSA vessels.
DANGEROUS VOLTAGE,
Forbidden to work on the
system if the power is on. The internal parts of the control cabinets, UPS control cabinets, junction
boxes and sensors. These parts are:
•
PCB’s within the control cabinets;
•
PCB of UPS control cabinet;
•
DC batteries of UPS control cabinet;
•
The applied voltages are: 24V AC, 24V DC, 230V AC, 380V AC.
DANGER OF INHALATION,
danger of asphyxiation if
breathing high concentration
of nitrogen.
Avoid the specified area to
avoid health hazards. The nitrogen output connection. The mixture produced by the nitrogen
generator consists of 95% or more nitrogen. Inhalation directly from the
output connection may cause intoxication. The nitrogen quickly mixes with
the ambient air so that at a distance of >0.5m from the nitrogen output
connection it no longer poses a health risk.
Description of hazard symbols
In addition to the identified risks for the nitrogen generator, the following symbols can also be applied within the system of
which the nitrogen generator is part of. When a hazard symbol is encountered, please observe its meaning carefully before
further commencing the work.
Symbool Omschrijving Symbool Omschrijving
1. OVERPRESSURE VALVE,
Be aware of the sudden relief of
overpressure. 7. HIGH PRESSURE,
Relief pressure from components before work
is conducted.
2. DANGEROUS VOLTAGE,
Forbidden to work on the system if the
power is on. 8. HOT PARTS,
Do not touch parts with bare hands. Use heat-
resistant clothing.
3. DANGEROUS TO INHALE GAS,
Avoid the specified area or wear appropriate
breathing equipment.
9. SUFFOCATION,
If the oxygen concentration is to low then do
not enter the room, risk of suffocation.
4. MACHINE WITH AUTOMATIC START,
Machine stops and starts automatically
when it is operating normally. Turn off the
machine completely before working on it. 10. ROTATING FAN,
Risk of getting stuck or injuries to limbs. Turn
the machine off completely before working on
it.
5. NOISE,
Wear ear protection to prevent hearing
damage. 11. ATTENTION,
Special situation occurs, follow additional
instructions.
6. READ THE OPERATING AND
MAINTENANCE INSTRUCTIONS,
It is advised that the maintenance
instructions are read before continuing
work. 12. MOVING PARTS,
Risk of getting stuck or injuries to limbs. Turn
the machine off completely before working on
it.
