Dangers of Carbon Monoxide

What it is?

Carbon Monoxide is a colourless, Odorless gas and it can harm you even at small concentrations. Carbon Monoxide (CO) displaces oxygen which binds with the hemoglobin and thus suffocates the body. Carbon Monoxide can harm you in low concentration over a period of several hours. However, in higher concentrations Carbon Monoxide can kill in less than five minutes.

Please see table published by CMHC (Canadian Mortgage and Housing Corporation) below for concentration of carbon monoxide and their effects:

CO concentration in parts per million (ppm)
0 – 2
Normal conditions in and outside Canadian houses.
Recommended exposure limit over a 24-hour period.3
Recommended exposure limit over a 1-hour period.3
CO detectors are not allowed to sound alarm unless this concentration is maintained for more than 30 days.2
CO detectors must sound alarm within 1 to 4 hours.2
CO detectors must sound alarm within 10 to 50 minutes.2
Slight headache, fatigue, dizziness and nausea after 2 to 3 hours. CO detector alarm must sound within 35 minutes.4
CO detectors must sound alarm within 4 to 15 minutes.2
Dizziness, nausea and convulsions within 45 minutes, death within 2 to 3 hours.4
Death within 1 hour.4
Danger of death after 1 to 3 minutes.4

How it is produced?
In a House Carbon Monoxide is produced by any fuel burning appliance which has malfunctioned or improperly installed, such as!
  • Furnace
  • Stove and Oven
  • Water heater
  • Dryer
  • Room and space Heater
  • Fireplace and wood Stove
  • Charcoal Grills

  • Get flues, dampers and chimneys inspected yearly by certified professional for any obstruction or crack.
  • If you have an attached Garage make sure the door between the garage and house is properly sealed and it has a self-closing devise.
  • Install Carbon Monoxide detectors in the house preferably on each floor and especially near sleeping area where it can easily be heard while sleeping. Furthermore, test them regularly for proper operation.

At RK Home Inspection we check all the Carbon Monoxide detectors present into your house. Recommend them if they are absent. Furthermore, we carry our own Carbon Monoxide detector to test the concentration of Carmon Monoxide concentration in the ambient air.
