Gas Monitoring Safety...
Nothing is more important than the safety of your workforce. It is vital to worker safety that gas monitoring instruments are calibrated regularly. Only properly calibrated gas monitoring instruments ensure worker safety from unseen atmospheric hazards.
When Do I Use Gas Detection Instruments?
Whenever a worker enters an area with potential atmospheric hazards, gas detectors are to be used. Gas detection instruments are used to detect the presence of toxic and combustible gases, as well as oxygen deficiency or oxygen enrichment.
Why Should I Calibrate?
Calibrating a gas detector sets the gas referencepoints to activate the alarms. Good gas monitorswith poor calibration can result in severe bodilydamage and even death.
Avoiding “Calibration Shift”
Occasionally an instrument’s gas reference point will shift. The reading will shift accordingly and be unreliable. This is called “calibration drift” and it happens to all detectors over time. Regular calibration with a certified standard gas concentration will ensure that the instrument will produce continued, accurate readings.
Where Should I Calibrate?
Calibrating gas detectors at locations where the equipment is to be used is always preferable. Electrochemical sensor response will be different (lower or higher) depending on the actual environmental conditions.
Alarms on Gas Detection Instruments
Most instruments are equipped with two levels of alarms – warning and danger. The warning alarm is for the detection of a gas level that is potentially hazardous. The danger alarm indicates a gas concentration at the “hazard” threshold.
