1.5. Warnings and Cautions – Sensor Use and Care
WARNING: EXTENDED EXPOSURE OF THE DEVICE TO HIGH CONCENTRATIONS OF
TOXIC GASES MAY RESULT IN DEGRADED SENSOR PERFORMANCE. IF AN ALARM OCCURS
DUE TO HIGH CONCENTRATION OF TOXIC GASES, EXIT TO A SAFE AREA AND BUMP TEST
OR RECALIBRATE AS NECESSARY.
CAUTION: Be aware of poisoned combustible sensors. The operation of catalytic type
combustible gas sensors may be seriously affected by silicones, free halogens, halogenated
hydrocarbons and metallic oxides present in the ambient air being monitored. If the presence of any
of these substances is suspected, increased frequency of calibration verification is recommended.
CAUTION: Exposure to sulfur compounds, halogens, silicone or lead containing compounds, or
phosphorus containing compounds can adversely affect the sensitivity of the combustible gas sensor.
Avoid exposure to these substances. Should you suspect that the device has been exposed to such
substances, perform a gas test to verify its accuracy and proper calibration.
