if you have a detector, you still may be at risk. 18 carbon monoxide detectors were put to an unscientific test by these firefighters. both new and used made by various manufacturers the detectors were mounted in a small room and carbon monoxide was pumped in produced by a generator. under writers laboratories require the devices to activate within 15 minutes of reaching an air concentration of 400 parts per million. prolonged exposure at that level can be fatal. but even lower levels can be dangerous, too. the firefighters expected the detectors to go off almost immediately. but they didn't. >> 525 parts per minute. >> at 525 parts per million only three detectors are going off. within 15 minutes 12 additional devices sound their alarms. so according to ul standards 15 of the devices worked as designed. but three others didn't. so what happened? well over time carbon monoxide detectors can break down. it's a warning you'll only find in small print. buried in manuals and industry reports. which say chemical and dust build up causes the detectors to lose their effectiveness. >> some people'
