GasAlertMax

Safety Information - Read First

a Cautions

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

BW Technologies immediately.

⇒ 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,

Replacement Parts and Accessories.)

⇒

Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor exposure to

poisons and contaminants. BW recommends at least once every 180 days* (6 months).

⇒ 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

S alarm if such a sensor is

fitted).

*Refer to Specifications.
