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.
CO is a toxin that is bound in blood where it prevents the transport of oxygen, which can cause death by suffocation.
Everyone is susceptible but experts agree that unborn babies, pregnant women, senior citizens and people with heart or respiratory problems are especially vulnerable to the dangers of CO.
Combustion appliances should always be installed by a qualified professional. Initial carbon monoxide poisoning symptoms are similar to the flu with no fever and can include:

1. dizziness

2. severe headaches

3. nausea

4. vomiting

5. disorientation

If symptoms of CO poisoning are experienced, seek medical attention immediately, CO poisoning can be determined by a carboxyhaemoglobin test.
The following symptoms are related to CO poisoning and should be discussed with all members of the household:

1. Mild exposure: slight headache, nausea, vomiting, fatigue (often described as flu-like symptoms).

2. Medium exposure: severe throbbing headache, drowsiness, confusion, fast heat rate.

3. Extreme exposure: unconsciousness, convulsions, cardiorespiratory failure, death.

The product will not trigger an alarm for other hazards such as gas leaks, fires or explosions. A CO detector is no substitute for smoke, fire, heat or other gas detectors.
The product is intended for use in household environments for typical housekeeping functions. It is not suitable for commercial or industrial applications or for use on recreational or commercial vehicles.
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.
This detector is intended to protect persons from the acute effects of CO.
The detector can not provide people with special medical properties complete security. If in doubt you should consult a physician.
Gas appliances/equipment should be installed by trained personnel only. Keep the devices/equipment in good mechanical condition and have them checked regularly
