The Phosgene Colorimetric SafeAir Dura-Badge is a monitoring system designed to indicate the presence of phosgene. The SafeAir Phosgene Dura-Badge detects the presence of phosgene by forming a color change in the shape of an exclamation mark inside the triangle. This indication is produced by a color-forming reaction, which occurs when phosgene reacts with a flat indicator layer.

Phosgene is a colorless, highly toxic gas with an odor resembling moldy hay. It is an insidious poison. There is no immediate irritation even when fatal concentrations are inhaled. It may cause severe pulmonary edema (abnormal fluid buildup in the lungs) or pneumonia. Inhalation of high concentrations causes choking, coughing and painful breathing. OSHA PEL (permissible) exposure limit for phosgene is 0.1 ppm (averaged over an 8-hour work shift). NIOSH IDLH (immediately dangerous to life or health) exposure limit for phosgene is 2 ppm. Phosgene is used in the manufacturing of numerous organic chemicals. It is also used in the production of glass, resins, dyes and plastics.

Operating Instructions

  1. Remove the badge from its protective pouch.
  2. Remove activation label prior to use.
  3. For personnel monitoring, attach the badge near the user’s breathing zone (i.e. the collar) with the front side exposed to the surrounding atmosphere.
  4. Between work shifts, store the badge in a sealed bag in a cool, dark environment.
  5. The exclamation mark appears within the triangle when phosgene is present. Please note that the exclamation mark will appear underneath the printed exposure dose (sensitivity).
  6. A color comparator is available for use with this badge. To obtain the average concentration, divide the exposure dose (ppm∙min) by the exposure time in minutes (min).
