scottfromiowa Posted August 5, 2012 Report Share Posted August 5, 2012 OSHA's former limit for carbon monoxide was 50 ppm as an 8-hour TWA. The ACGIH has a TLV-TWA of 50 ppm with a TLV-STEL of 400 ppm. NIOSH (1973d/Ex. 1-237) recommends an 8-hour TWA limit of 35 ppm with a 200-ppm ceiling. The proposed PEL and ceiling were 35 ppm and 200 ppm, respectively; NIOSH (Ex. 8-47, Table N1) concurs that these limits are appropriate, and they are established in the final rule. Carbon monoxide is a flammable, colorless, practically odorless gas. (Above from Web) Carbon Monoxide IS B.A.D. medicine. Prevention and detection is key. If you don't have a CO monitor in addition to smoke detectors in home too...think about cost vs. consequences. I had many overcome with poor forklift exhausts in winter in large warehouses...a small cockpit at altitude is no place to be overcome...

danb35 Posted August 5, 2012 Report Share Posted August 5, 2012 A pulse oximeter won't show CO issues. CO binds to the red blood cells and "reddens" them like O2, so there's no color difference for the pulse-ox to detect. I wouldn't bother with a panel-mount CO meter, but I do have a battery unit in 48Q. I do get some beeps on the ground and at lower altitude climb, but not at cruise.

danb35 Posted August 6, 2012 Report Share Posted August 6, 2012 The stick-on chemical dot detectors are worse than useless. They're slow to react, and don't react at all until the CO concentration is far higher than you should let it get. I bought a portable electronic detector for around $100 when I bought '48Q, and the sensor is good for 5 years. It looks like there are some other good options on the market now, so I may get something different when I replace it. Mine is similar to this one: http://www.aeromedix.com/CO_Experts_Low_Level_Detector_Model_2010.html (but I recall the price being quite a bit lower at the time).

AmigOne Posted August 6, 2012 Report Share Posted August 6, 2012 How about home CO detectors? a friend of mine uses one in his Bonanza and says that as far as sensitivity it has tested very well. He is the technical director of a company that manufactures precision measuring instruments so I imagine that he knows something about the subject. They can be a bit bulky but I guess they still can be placed somewhere under the panel. Quote Link to comment Share on other sites More sharing options...

danb35 Posted August 6, 2012 Report Share Posted August 6, 2012 The issue with home CO detectors is low sensitivity (required by UL rating standards): http://www.aeromedix.com/aeromedix_articles/co/index.html Quote Link to comment Share on other sites More sharing options...
aviatoreb Posted August 6, 2012 Report Share Posted August 6, 2012 I agree completely with the importance of a CO detector. I recently had a cracked exhaustpiece replaced - late June. That crack showed up on my CO detector. I have this little unit clipped near the visor: http://www.aircraftspruce.com/catalog/pspages/co300.php It seems to work. It can detect the slight variations between taxi (5 to 8ppm) and cruise (generally 2 or less ppm). Its cheap, light and sticks easily with velcro.

Oscar Avalle Posted August 16, 2012 Report Share Posted August 16, 2012 Well after about three months of hard work my panel upgrade is finished... I also redid the interior.... Although I have to say I am a little bit concerned about information overload. Any recommendations... Oscar Quote Link to comment Share on other sites More sharing options...
