Special Co5. nditions for Safe Use
The portable gas detector Impact Series by Honeywell Analytics Ltd. is •
based on the information and test results contained in the test reports
PFG-No. 41300502P and PFG No. 41300502P NI to 41300502P NIV,
suitable for the measurement of Carbon Monoxide up to 500 ppm CO,
Hydrogen Sulfide up to 50 ppm H
2
S, Carbon Dioxide up to 2% CO
2
and
Oxygen up to 25% (based on the use for monitoring the atmosphere of
oxygen deficiency and enrichment), if its properties and design conform
to the documents listed in the test reports PFG-No. 41300502P and PFG-
No. 41300502P NI to 41300502P NIV if it is used accordingly and if the
following conditions are met:
The operating (manual) presented and approved by EXAM is to be followed •
in detail. It is essential that the instructions for correct use are followed.
Before operating the gas detector, check whether the response is fast •
enough to trigger alarms sufficiently quickly to avoid unsafe situations.
If necessary, set the alarm levels well below the standard safety-related
limit values.
A calibration for the instrument with a measuring range of 0-2% CO•
2
must
only be performed at temperatures above 10°C and below 30 °C.
A permanently displayed value of -0.0 in the measuring range of 0-2% •
CO
2
requires an immediate calibration of the instrument.
Following exposure to CO•
2
concentrations above the upper limit of the
measuring range 0-2% CO
2
, leave the instrument in clean air overnight
before calibration.
The first alarm level (A1) in the measuring range of 0-2% CO•
2
must not
exceed 0.5% CO
2
.
For the measuring range 0-2% CO•
2
the STEL and LTEL time weighted
average values may exceed the true values due to the behavior of the
sensor.
It should be noted that sampling of oxygen deficient gases using the •
integrated pump could result in measured/displayed values being slightly
higher than permitted.
When extracting gases with the integrated pump in combination with •
additional probes the increased response time needs to be taken into
consideration.
The calibration needs to be checked, especially that of the H•
2
S channel, if
the instrument was subjected to excessive mechanical shock (e.g. dropping
the instrument from normal operational height).
The confidence beep must be activated.•
The BG information BGI 518 and BGI 836 (4,5) need to be read and •
understood.
The instruments shall be labelled with a permanent label, including •
information regarding the manufacturer, type and serial number and the
inscription:
PFG-No. 41300502
