The safety of personnel is always the
highest priority. This is the main reason
why a gas detection device should be
checked daily by conducting a bump test
to guarantee the correct functioning.
Measuring instruments which do not function
correctly do not have any protective
function and this can result in accidents,
because an exposure to high concentrations
of toxic gases or oxygen shortage can
lead to illness or death.
The Dräger bump test station is designed
to perform a bump test (also known as
a function or a challenge test) with gas
in order to test detection and warning
instruments. This test is important to check
whether the gas being measured is flowing
through the dust and water filter to the
sensor, to check the sensor calibration, to
check that the alarms are working and are
correctly set, and to check compliance with
specific national requirements, standards,
recommendations etc.
A Dräger calibration gas bottle containing
the gas being measured is connected
to the bump test station, which houses
an integrated gas regulation valve and a
device-specific adapter for various measuring
instruments.
The bump test station can be used to test
the following detectors and warning instruments:
the new single-gas detectors Dräger
Pac 1000 / 3000 / 5000 / 7000, Dräger
X-am 3000 and Dräger X-am 7000. The
Dräger bump test station and the necessary
adapter to connect the various gas detectors
will be available for each instrument.
The first bump test station is for the Dräger
Pac instruments. The bump test stations for
the other measuring instruments will be
launched soon.
For all of the detectors available so far the
bump test will be performed manually. This
means that the person conducting the test
decides when the bump test has been successfully
completed. The user sees and
hears the alarm, and compares the displayed
concentration against the concentration
of the test gas.
Testing an instrument with a known gas
concentration is the only way to guarantee
reliable and correct measurement of and
warning against gas hazards. This type of
test checks that the sensor is responding
correctly and that the instrument's alarms
are working as they should be.
