Warning
Pure Hydrogen is a flammable gas. Use only ready-made Hydrogen Tracer Gas
comprising 5% Hydrogen in Nitrogen. This is a standard industrial gas mixture used
in a variety of industrial applications.
Warning
Since the tracer gas mix contains no oxygen, releasing large amounts of the gas in a
confined space may lead to asphyxiation.
Warning
Compressed gases contain a great deal of stored energy. Always carefully secure
gas bottles before connecting a pressure regulator. Never transport gas bottles with
a pressure regulator fitted.
