3.2.1 Handling the Balloon
It is recommended that the balloon be prepared in a balloon-filling shed.
The
balloon-filling shed must be well ventilated so that possible gas leaks do not remain
inside the shed, even in situations when there is no electricity.
WARNING!
When handling the balloon, use protective gloves to avoid damaging the balloon surface.
Even minor grease stains can damage the balloon, causing premature balloon burst.
1. Open the balloon package carefully. To avoid damaging the balloon, do not use a knife
or other sharp objects to open the package.
2. Check visually that the balloon is structurally sound and has no perforations or other
apparent defects in the nozzle section.
3.2.2
Filling the Balloon
1. Connect the side tube of the filling balance to the pressure reducing valve on the gas
cylinder (or hydrogen generator) with a flexible plastic hose.
2. Select the nozzle which best fits into the neck of the balloon.
3. Load the additional weights that are needed to obtain the required lift, for example,
Vaisala Filling Balance FB13 weights as in the
figure below.
