Description / Phosgene Dura SafeAir Color Comparator
Color change for Phosgene Dura is from white to red.
The SafeAir Phosgene Dura badge may be used for personnel or area monitoring for exposure times from 1 minutes to 5 days. For higher resolution, the color comparator can be used with the SafeAir phosgene Dura-Badge (part number: 382065-50).
Introduction
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 build up in the lungs) or pneumonia. Inhalation of high concentrations causes choking, painful breathing and coughing. 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.
Principle of Operation
The SafeAir Phosgene 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.
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. To obtain the average concentration, divide the exposure dose (ppm∙min) by the exposure time in minutes (min).
Storage
The ChromAir phosgene monitor should be stored at 25C in its sealed bag at all times. It's best to store the badge in a cool, dark, sealed environment between work shifts.
