1.0 SAFETY
NOTE: The safety guidelines included here may not cover every
situation. Use common sense.
1.1 General Information
For this unit to generate electrical power, a supply of hydrogen fuel is necessary.
It is important for any operator to be aware of, understand, and follow all local
safety requirements related to the handling of hydrogen and compressed gases.
The fuel cell system has built-in safeguards and is designed to shut down
automatically if any out-of-range operating condition occurs. Possible situations
include low cell voltage, high current, high temperature, or hydrogen leak
detection.
• Do not dismantle the H-500XP system . Contact HORIZON if you have any
concerns about operation.
1.2 Using Hydrogen
WARNING! FIRE OR EXPLOSION
Keep all sources of ignition away from hydrogen.
This unit uses hydrogen fuel. Hydrogen is a colorless, odorless and flammable
substance. It is highly combustible in the presence of oxygen and burns with a
colorless flame.
Leaking gas may be hot and pose a burn danger. Stop the flow of gas – if you are
not in danger – and use water to cool the area. If fire occurs, do not attempt to
extinguish flames, allow the fire to burn out.
Prevent overexposure to hydrogen. Hydrogen is non-toxic but can act as a simple
asphyxia by displacing the oxygen in the air. There are no warnings before
unconsciousness results. When operating the H-500XP power module in an
enclosure:
• Ensure ventilation slots are clear and unobstructed at all times during operation
• Operate within the temperatures limits stated on the H-500XP system
nameplate
• Never operate if an alarm condition exists
1.3 Handling Compressed Gas Cylinders
WARNING!
Do not handle compressed hydrogen gas cylinders without
training or experience.
