3.2 Preparing the Radiosonde Balloon
Read the safety instructions in Safety Instructions for Balloon Operators
(page 33) before proceeding. Normally the balloon-lifting gas (hydrogen or helium) is
supplied in gas bottles, but hydrogen can also be produced with a hydrogen generator.
Carefully study the operation and safety instructions for the gas bottle facilities or the
hydrogen generator.
Take extreme caution when handling the inflated balloon.
WARNING!
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!
