B 100 Safety instructions
The normal risks associated with working with all compressed gases must be
considered.
Leak detector label
Located at the back of the Sensistor ISH2000, a label indicates the electrical
specifications of the leak detector and its serial number.
Indicates a potentially hazardous situation which, if not avoided, could result in
property damage.
Indicates a potentially hazardous situation which, if not avoided, could result in
moderate or minor injury. It may also be used to alert against unsafe practices.
Indicates an imminently hazardous situation that, if not avoided, will result in death or
severe injury (extreme situations).
Indicates a potentially hazardous situation which, if not avoided, could result in death
or severe injury.
Before connecting tracer gas: confirm that the connectors or test object is designed
for working at the test pressure.
WARNING!
Pure hydrogen is a flammable gas. Only use ready-
made Hydrogen Tracer Gas of 5% Hydrogen in
Nitrogen. This is a standard industrial gas mixture
used in various industrial applications.
Note: Whenever the word Hydrogen is used in
this manual it implies that the hydrogen gas is
safely mixed with Nitrogen in the proportions
5% H

- 95% N

.
WARNING!
Since the tracer gas mix contains no oxygen,
releasing large amounts of 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 pressure regulator. Never transport gas
bottle with the pressure regulator fitted.
WARNING!
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.
