Dräger X-am 2800 Notice D'utilisation page 21

WARNING
Risk of explosion!
If the CatEx sensor is exposed to hydrogen and low
temperatures (< -10 °C) for a long time (> 1 h), measured
values that are too low may be displayed. This also applies if
hydrogen is being measured but the measured gas set is not
hydrogen.
► The CatEx sensor should be set to the measured gas
"hydrogen"for regular and planned measurements of
hydrogen. Measuring tasks which last less than 30 min.
are not affected by this.
Increased hydrogen concentrations within the measuring
range of the DrägerSensor XXS H
may trigger false alarms by additively influencing Dräger
sensors XXS H S and XXS CO, XXS H
2
LC, and negatively influencing DrägerSensor XXS O
XXS O PR.

Short time exposure limit, threshold of an
exposition over a short period of time (gen-
erally 15 minutes).
Time weighted average, average shift val-
ues are generally limited to eight hours
exposure per day per workplace for 5 days
a week during a work lifetime. Observe the
national definition of the occupational
exposure limit.
