To avoid possible personal injury:
⇒
Warning: Substitution of components may impair Intrinsic Safety.
⇒
Do not use the detector if it is damaged. Before you use the detector, inspect the case. Look for cracks or
missing plastic.
⇒
If the detector is damaged or something is missing, contact
⇒
For use only in potentially explosive atmospheres where oxygen concentrations do not exceed 20.9% (v/v).
⇒
Make sure the back is closed and fastened, and the battery is locked in place before you operate the detector.
⇒
Use only a sensor specifically designed for your GasAlertMax model. (See the section,
and
Accessories.)
⇒
Periodically test the sensor's response to gas by exposing the detector to a targeted gas concentration that
exceeds the High Alarm setpoint. Manually verify that the audible and visual alarms are activated.
⇒
Prior to each day's usage sensitivity must be tested on a known concentration of the target combustible gas
(methane, etc.) equivalent to 25-50% of full-scale concentration (accuracy must be within 0 to +20% of actual).
Accuracy may be corrected by recalibrating the instrument.
⇒
It is recommended the detector be calibrated before first-time use, and then at least once every 180 days.
⇒
Do not turn off the detector during a work shift. Turning off the detector resets the TWA (time-weighted
average), STEL (short-term exposure limit), and maximum gas exposure values to 0. (See the section,
Alarms.)
⇒
It is recommended that the accuracy of the GasAlertMax be checked with known concentration calibration
gas before each day's use and immediately after any known exposure to contaminants (e.g., after an H
alarm if such a sensor is fitted).
