SafeAir* Badges

These badges provide an immediate visual indication when a specific chemical hazard is present. The sensor is constructed from a coated indicator layer that is highly sensitive and selective to the targeted chemicals. A color change, in the form of an "exclamation point"� warns of the presence of the targeted hazard. The badge requires minimal training. There is no calibration, extra equipment or laboratory analysis required. A dual-purpose badge is available for chlorine and chlorine dioxide. It selectively indicates the presence of chlorine on the front side of the badge and chlorine dioxide on the back side. Indications may appear on both sides if both chemicals are present. The mercury and 1,1-dimethylhydrazine badges provide the user with two independent threshold levels. The front of the badge indicates one threshold level while the back provides a second level.
MRST = Maximum recommended sampling time.
