During my morning inspection yesterday I started to feel light headed, dizzy and foggy. I test the house for CO (zero), so I thought it might be formaldehyde from the flooring. But that was not it: according to the flooring labeling. Then I remembered that I started to feel strange after coming out of the attic (20+ minutes up there checking out the running furnace and small attic space). The real estate agent and buyer both were not affected while in the house. I left to do my afternoon inspection but returned (feeling 95% better) to check the CO levels in the attic and garage (in case the WH & furnace flues were leaking)…All zero CO but I had the symptoms of CO. Then I tested with my combustion gas monitor and it detected something (performed the test 3 times with the same results), no smell of gas though. The gas company paid a visit but said there was no gas detected (so they say).
Did you re-experience the dizziness on your revisit to the attic? If not, maybe some sort of one-off thing. It takes very high CO levels to affect you in 20 minutes. I’ve been in 100 ppm for 30 minutes with no symptoms, though that level had made the tenant very ill. So, if not a one-off bad morning, then maybe a mild allergic reaction to some dust you stirred up.
Sorry to read of your recent experience. its a good reminder to us all about the potential dangers we face at some properties.
I hope someone has a good explanation for you.
I’m stumped by the lack of an odor for a chemical or gas that would cause dizziness. Besides CO or Propane or Natural gas leaks there could be sewer gas leaks but CO is the only one on that list with no odor associated, and you already tested for that.
I hope another member knows of a substance in the attic that might be the culprit.
It could be a lot of things that caused it. None of us are doctors. It also has nothing to do with your physical health or your activities.
A friend of mine would get the same symptoms at different times throughout the day, almost every day at work. They had the fire department come in and run tests on multiple days and they could not find anything. The doctor told him to keep a log of his activities. What they found out was that the harmonics of a motor vibrated the floor just enough to cause it. For whatever reason, he is the only one affected by it. The same thing could have happened to you with the blower motor on the furnace.
There seems to be a focus on health and not the gas detector, which detected something 3 times. Each time I started from the outside of the house after auto-calibration, slowly walked inside towards the garage. While in the garage I walked around and then pointed the gas detector in the attic hatch. Each of the 3 times that is when the detector went fill tilt. I took a video of the gas test but it was too large to upload. Just now edited it so it fits under 100mb, the last 5 seconds is the alert. I will see if I can add it to the main comment above.
To begin with… you need to use the proper test equipment for the job.
The Klein ET120 does NOT test for CO or other NON-combustible gasses!
Klein states it only tests for Methane, Propane, Butane, as low as 50 PPM.
