1. Personal Gas Analyser
It is recommended that gas detectors should be checked before every use by bump testing, this may vary by equipment type & application with some gas detectors requiring more frequent testing & calibration, to ensure accurate measuring of gas concentrations.
All types of gas detectors will require periodic recalibration using appropriate calibration gases. Where sensors are used that have definite service lives and/or susceptibility to poisoning (e.g. catalytic, electrochemical, semi-conductor) regular recalibration, or at least response checking, will be required. The required frequency may be specified by the regulations of the responsible authorities. In most cases, advice or recommendations can
be obtained from the manufacturer.
For your periodic testing & Calibration of Gas Detectors, contact Powerpoint Engineering.
Examination before use
Here are some checks you should carry out each time before use & also refer to the manufactures checks as well before use, Inspect the gas detector for damage, that it is clean & fully charged, field-checks are intended to verify that the apparatus is in a good working state.
It is recommended that these checks are done by a trained & competent person who is going to operate the gas detector.
Powering on & Carry out a fresh air setup/startup, allow time to stabilize or zero out & accurately measure
Check that the functions of the Gas detector are working correctly in accordance with the manufacturer, L.C.D screen segments activate briefly, Alarms L.E.D, S flash briefly, horn sounds briefly, vibrating alarm triggers briefly & any additional alarms function correctly
You should carry out a bump test of the gas detector before use every day
You should check that the sensors & alarm set points are set correctly for your work location
You should check that there is no sensor warning on the gas detector, & it is functioning correctly, if there is doubt or there is a warning, do not use the gas detector and you should send it for Calibration
If the gas detector fails a bump test, do not use the gas detector and you should send it for Calibration
If the gas detector has been dropped or exposed to physical shock do not use the gas detector and send it for Calibration
If there is any doubt that the gas detector is not functioning correctly it should be removed from service and or you should send it for calibration or repair.
Precautions in Use
Here are some precautions to be aware of but there may be other precautions that you may need to take into consideration that are not listed here.
Only trained & competent persons should use the gas detector.
The personnel gas detector should be fully charged clipped at chest high in your personnel breathing space.
Follow all relevant manufacturer & national regulations applicable in the country of use.
Check during use that the gas detector is still on and the battery has not died, if it has died immediately leave the work area to safety.
Check during use that there is no warning on the gas detector, if there is a warning or if the alarm goes off immediately leave the work area to safety.
Do not use the gas detector to test for combustible or toxic gases in the following atmospheres as this may result in erroneous readings: Oxygen-deficient or rich atmospheres, reducing atmospheres, Furnace stacks, Inert environments, Atmospheres containing combustible airborne mists/dust. Use the device only to detect gases/vapours for which a sensor is installed.
When Using the gas detector, it should be used as designed, and it should not be
mistreated or abused
Personnel Gas Detectors should be tested in accordance with IEC standards or to industry Best Practices.
