By the time you can smell phosgene, you've already been exposed to a hazardous dose of it. Because of this, prolonged exposure to phosgene without intervention is possible. The OSHA permissible exposure limit to phosgene is 0.1 ppm averaged over an 8-hour workshift. Phosgene is considered immediately dangerous to life or health at 2 ppm. Because the odor detection threshold is 0.4 to 1.5 ppm, odor does not provide sufficient warning of harmful phosgene concentration in the air. | By the time you can smell phosgene, you've already been exposed to a hazardous dose of it.

| − | If you think you may have been exposed to phosgene, move outside or to fresh air. Phosgene is heavier than air, and will sink, so move to higher ground if possible. If your eyes are burning or your vision is blurred, rinse your eyes with fresh water for 10 to 15 minutes. Seek medical attention. | + | If you think you may have been exposed to phosgene gas, move outside or to fresh air.
