Safety Information
Before you start working with the Horizon DIY take notice of the following. Under certain
circumstances, hydrogen can create an explosive gas mixture. Though these devices in
this box are designed such that they can be used as described without danger, the advice
below must be followed at all times:
•
The fuel cell and hydrogen storage may not be operated without supervision of
adult person.
•
Hydrogen (H
2
) is much lighter than air and thus rises rapidly. In conjunction with
oxygen, a gas mixture capable of explosion can form. A potentially explosive
mixture arises for hydrogen concentrations from 4.0 to 77.0% in air. Therefore, it
holds that:
•
The fuel cell must only be operated either outside or in sufficiently ventilated
rooms.
•
Oxygen (O
2
) is a strongly oxidizing gas. When this gas gets in contact with organic
substances (e.g. oil, grease) spontaneous combustion may occur at room
temperature.
•
Do not insert the cables into an electrical outlet.
•
Do not connect the fuel cell or motor to other power sources.
•
The removing and inserting of batteries is to be conducted by the adults only.
Ensure to respect the polarity.
•
Non-rechargeable batteries are not to be recharged.
•
Different types of batteries such as rechargable, alkline and standard batteries or
new and used batteries are not to be mixed and should be used separately.
•
The battery pack cables are not to be inserted into an AC socket.
•
The supply terminals of the battery pack are not to be short-circuited.
•
The two spare red & black cables are not to be inserted into an AC socket.
•
Exhausted batteries are to be removed from the battery pack.
•
Dispose of dead batteries properly and without delay.
•
Do not attach the battery wires directly to each other.
