WARNING!
• Pure hydrogen is a flammable gas. Only use ready-made Hydrogen Tracer Gas
of 5% Hydrogen in Nitrogen. This is a safe, standard industrial gas mixture used
in various industrial applications. The normal risks associated with all compressed
gases must however be considered. As the tracer gas mix contains no oxygen,
releasing large amounts of gas in a confined space may lead to asphyxiation.
• Whenever the word Hydrogen tracer gas is used throughout this manual it
implies that the hydrogen gas is safely mixed with Nitrogen in the proportions
5% H

- 95% N

.
• Compressed gases contain a great deal of stored energy. Always carefully
secure gas bottles before connecting pressure regulator. Never transport gas
bottle with pressure regulator fitted.
• Before connecting tracer gas: confirm that the connectors or test object is
designed for working at the test pressure.
• Pressurising objects at too high pressures can result in a burst object. This in
turn can result in serious injury or even death. Never pressurise objects that
have not previously been burst tested or otherwise approved for the chosen test
pressure. INFICON can not take any responsibility for the consequences arising
from the inapropriate use of certain test pressures.
• Pressure shocks might cause strong sounds which can cause impairment of
hearing.
• Charge battery in safe area only! Read the section ”Special conditions for safe
use” on p. 5 and ”10. Charging” on p. 38, before using the instrument.
• Check that all relevant legislation and safety standards are complied with
before putting Extrima into service.
