When it comes to highly toxic gases like phosgene, early detection is critical. The SafeAir® Phosgene Detection Badge (382036-50) offers a simple, visual, and reliable way to monitor for this dangerous gas in workplaces and industrial environments. Designed for both personnel and area monitoring, this color-changing badge provides clear warnings of hazardous conditions without the need for electronic equipment.
What Is Phosgene?
Phosgene is a colorless, toxic gas with a smell similar to moldy hay. It is a silent threat—highly dangerous even at low concentrations, and especially insidious because it causes no immediate irritation, even at potentially fatal levels. Exposure can result in pulmonary edema, pneumonia, and other serious respiratory effects.
- OSHA PEL: 0.1 ppm (8-hour time-weighted average)
- NIOSH IDLH: 2 ppm (immediate danger to life and health)
Used in: Chemical manufacturing, glass production, plastics, dyes, and resins.
How the SafeAir Phosgene Badge Works
The SafeAir badge uses a colorimetric detection method to alert users to the presence of phosgene. When phosgene is detected, a yellow triangle displays a red exclamation mark, providing a clear and immediate warning.
- Color change: Yellow ➝ Red
- Detection: Begins within 1 minute
- Exposure range: 0.5 to 450 ppm∙min
- Minimum detectable limit (8 hrs): 0.002 ppm
- Sampling time: 1 minute to 3 days
This passive monitor works without batteries, calibration, or pumps, making it ideal for continuous monitoring or short-term spot checks.
Where and How to Use It
The SafeAir badge can be used for:
- Personnel Monitoring: Clip it to the collar near the breathing zone.
- Area Monitoring: Mount on a stand in the center of the monitored space.
Operating Instructions:
- Warm the badge to room temperature (remove from refrigeration).
- Remove from pouch and peel off activation label.
- Expose badge to the environment—either on a person or in a room.
- Monitor for the appearance of the red exclamation mark in the triangle.
- To determine average concentration:
Exposure Dose (ppm∙min) ÷ Time (min) = Average ppm
Storage and Environmental Conditions
- Shelf life: 1 year (refrigerated)
- Temperature range: 55°F to 99°F
