Dangers of Carbon Monoxide

Exposure to Carbon Monoxide (CO) is very dangerous. CO is a colourless, odourless and tasteless gas that deprives oxygen from the area. This can be fatal.
CO is generated by combustion of carbonaceous materials, mainly when not enough oxygen is available. This can occur for example by malfunctioning or misuse of appliances used for heating and cooking or by vehicle engines, blocked chimneys, fireplaces, boilers, stoves and any other fuel burning appliance within a confined area.

When exposed to CO, the following symptoms will occur:

Concentration of CO in air. (ppm = parts per million)

Symptoms

---|---

50ppm

The maximum allowable concentration for healthy adults to be exposed to in a 8-hour period.

200ppm

Within 2-3 hours of exposure:

slight headache

fatigue

dizziness

nausea

400ppm

|

Within 1-2 hours of exposure:

frontal headaches

WARNING : 3 hours of exposure will result in death.

800 – 999 ppm

|

Within 45 minutes of exposure:

dizziness

nausea

convulsions

unconsciousness

WARNING: 2-3 hours of exposure will result in death.

This product does not prevent the chronic effects of carbon monoxide exposure and will not fully safeguard individuals at special risk.
The installation of the product should not be used as a substitute for proper installation, use and maintenance of fuel fired facilities, including appropriate ventilation and exhaust systems.

Not in turbulent air (near windows, ceiling fans or air conditioners).
Not behind objects (curtains or closets).

Other areas:

Not in turbulent air (near windows, ceiling fans or air conditioners).
Not behind objects (curtains or closets).
For optimal CO detection install the product at breathing height.
For optimal smoke detection install the product at a minimal height of 1.80 m.

Do not install the product:

in dirty, greasy or dusty areas.
in temperatures below 0 ºC.
in temperatures above +40 ºC.
in turbulent air (near ceiling fans, air conditioners or open windows).
within 3 meters of a high humidity source.
within 1.5 meters of kitchen appliances.
within 6 m of a furnace or fuel burning heat sources.
behind objects like curtains or closets.
