The SafeAir^® system consists of a direct reading colorimetric badge and a color comparison chart. SafeAir badges are available for 21 different gases.

• Provides immediate visual indication when specific chemical is present
  
• Homogeneous and stable color formation due to coated indicator layer
  
• Highly sensitive and selective
  
• Ideal for leak detection and daily exposure screening
  
• No laboratory analysis needed

Principle of Operation
The SafeAir badge provides an immediate visual indication when a specific chemical hazard is present. The sensor in the SafeAir badge is constructed from a coated indicator layer rather than impregnated paper, thus providing homogeneous and stable color formation. The indicator layers are highly sensitive and selective to the targeted hazard. A color change in form of an "exclamation mark" warns the presence of the targeted hazard. SafeAir is a low cost chemical detector badge allowing companies to perform daily exposure screening. The badge requires minimal training. There is no calibration, extra equipment or laboratory analysis required.

SafeAir Color Comparators
To determine exact exposure dose, the SafeAir badges can be used with a SafeAir color comparator. Insert your exposed SafeAir badge into the color comparator with the exclamation point facing up. Turn the color comparator wheel until the upper half of the exclamation mark (on the badge) matches the lower half of the exclamation mark (on the color comparator). Now read the exposure dose in the exposure dose window and divide it by your sampling time to obtain your average concentration.

SafeAir Color Comparators are available for the following compounds:

• Arsine (for use with the SafeAir hydrides badges)
• Carbon Dioxide
• Chlorine
• Chloroformate (for use with the SafeAir phosgene badges)
• Diborane (for use with the SafeAir hydrides badges)
• Hydrazine
• Hydrogen Chloride
• MMH (for use with the SafeAir hydrazine dual level badges)
• Phosgene
• Phosphine (for use with the SafeAir hydrides badges)
• TDI
• UDMH
