I have been on a house boat for 3 days and didn't realize until today that my carbon monoxide detector was reading from 36-62 ppm. Will I suffer any sort of brain damage from longish exposure to small amounts?
Answer
The problem with carbon monoxide is that it competes with oxygen for a place on haemoglobin molecules (inside red blood cells). Since your body needs oxygen, not carbon monoxide, if the latter takes the place of oxygen, the body can become hypoxic (short of oxygen).
Matters are made worse by the unfortunate coincidence that carbon monoxide binds with about 250 times the tenacity as oxygen, which means that it often takes a long time (hours to days) before all of it is eventually replaced by an oxygen molecule again. But eventually it is, and things return to normal.
The point is: now that you're off the house boat, you are over the worst. If you are feeling fine now, you will stay fine. This is not one of those conditions where you take a hit now, and it whacks you suddenly months or years later! So don't worry... but look into fixing the problem on the house boat!
Hope that helps!

carbon monoxide detector keeps beeping?
KillingMot
I have two carbon monoxide detector. My upstair carbon monoxide detector keeps beeping every 2-4 minutes. It also has a number saying 52. The carbon monoxide downstair appears to be fine, althrough it doesnt have that displaying number thing. I tried switching the carbon monoxide with each other, and now neither beeps anymore. But one of the carbon monoxide detetor(the one from upstair then switch to downstair) still says 52. Should i be concern?
Answer
Although all home detectors use an audible alarm signal as the primary indicator, some versions also offer a digital readout of the CO concentration, in parts per million. Typically, they can display both the current reading and a peak reading from memory of the highest level measured over a period of time. These advanced models cost somewhat more but are otherwise similar to the basic models.
The digital models offer the advantage of being able to observe levels that are below the alarm threshold, learn about levels that may have occurred during an absence, and assess the degree of hazard if the alarm sounds. They may also aid emergency responders in evaluating the level of past or ongoing exposure or danger.
The alarm points on carbon monoxide detectors are not a simple alarm level as in smoke detectors but are a concentration-time function. At lower concentrations (eg 100 parts per million) the detector will not sound an alarm for many tens of minutes. At 400 parts per million (PPM), the alarm will sound within a few minutes. This concentration-time function is intended to mimic the uptake of carbon monoxide in the body while also preventing false alarms due to relatively common sources of carbon monoxide such as cigarette smoke.
CONCLUSION: YOU ARE SAFE AT 52.
