Symptoms of Carbon Monoxide poisoning

Symptoms of Carbon Monoxide poisoning

The symptoms of CO poisoning are similar to those of a viral infection, such as headache, nausea, dizziness, sore throat and dry cough. The seriousness of the poisoning depends from the concentration of CO in the air and the duration of exposure.

  • At 50ppm (parts per million), an exposure for longer than 30 minutes will start to affect your health.
  • At 200ppm you will get a slight headache after 2-3 hours.
  • At 400ppm strong frontal headache, becoming widespread after 3 hours.
  • At 800ppm Dizziness, nausea, convulsions, insensible after 2 hours.
What is Carbon Monoxide?

What is Carbon Monoxide?

Carbon Monoxide is created as a by-product of incomplete combustion of fuels containing carbon such as wood, gas, oil, etc. It occurs, if boiler flues are getting blocked, chimneys close up or if gas flames are not correctly adjusted. As Carbon Monoxide (also called short CO) cannot be smelled or tasted the increase in CO concentration goes unnoticed. However, even slight increases of CO have serious health implications. You therefore need Carbon Monoxide detectors to find out if you have CO in your building. If your detector goes off, switch off all fuel burning appliance, open all windows and leave the building. You then need to call your gas provider.

How do Carbon Monoxide Detectors display the presence of CO?

How do Carbon Monoxide Detectors display the presence of CO?

There are largely two alternative ways for a carbon monoxide alarm (CO alarm) to display the presence of dangerous levels of carbon monoxide:

  • LED warning lights together with an alarm siren
  • Digital display of actual CO concentration readings and an audible alarm when dangerous levels are reached.

CO detectors with LED display will only trigger an alarm at over 50ppm (number of CO molecules per million air molecules), a level that ignores the damaging impact of long term lower concentration exposure, believed to be somewhere around 20ppm. This limitation is unfortunately cast in iron by a British Standard.

CO detectors with digital display, while still only audibly alarming at over 50ppm, will at least display the actual CO concentration, even at very low concentrations such as 10ppm. Some of them, for example the CO9D detector, will even allow you to read the maximum concentration of CO the detectors has measured since the last query by pressing a button.
