Information on carbon monoxide

What is carbon monoxide (CO)

Carbon monoxide is an odourless, tasteless, highly toxic and flammable gas produced by the incomplete combustion of carbon-based fuels. Prolonged exposure to a carbon monoxiderich environment leads to serious tissue damage or even death.

What are the symptoms of carbon monoxide poisoning?

• Mild exposure (about 100-200 ppm): mild headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms).
• Medium exposure (about 400 ppm): violent throbbing headache, drowsiness, confusion, fast heartbeat.
• Extreme exposure (about 800 ppm): unconsciousness, convulsions, cardiorespiratory failure, death.

symptoms).
200| Dizziness and headache within 2-3 hours.
400| Nausea, frontal headache, drowsiness, confusion and rapid heart rate.
Risk to life after over 3 hours of exposure.
800| Severe headaches, convulsions, vital organ failures.
Death possible within 2-3 hours.

Where does carbon monoxide come from?

Carbon monoxide is caused by poor or incomplete combustion.

• A furnace, boiler, cooker, pellet stove, fireplace, wood stove, charcoal grill can be sources of carbon monoxide, especially if they are not working properly or if they are located in a poorly ventilated room.
• Vehicle exhaust gases in enclosed spaces (garage) can also become carbon monoxide hazards.
• With the use of paraffin heaters or charcoal grills/bbqs indoors or running a car in a garage, carbon monoxide levels can get so high that it can cause death.

How do I know if carbon monoxide is present?

Poisoning is measured in a range called parts per million (ppm).
This CO Alarm monitors the level of carbon monoxide (CO) in the  air. If the CO concentration is too high, the detector sounds a loud alarm. When the alarm sounds, warn all household members, go outside immediately and call 112.

How do I protect myself and my family from carbon monoxide poisoning?

• Install one or more carbon monoxide detectors in your home.
• Have your home’s heating system, boiler and other gas, oil or coal appliances checked every year by a competent person or company.
• Make sure that your combustion appliances and engines are well ventilated.
• Have your chimney checked and cleaned every year.
• Use gas appliances as recommended. Never use a gas cooker or oven to heat indoor areas.

What should I do if the carbon monoxide detector goes off?

When the carbon monoxide concentration reaches a dangerous level, the carbon monoxide detector emits a loud alarm signal (85dB) and the Alarm LED flashes rapidly.

• Inform all household members of the danger.
• Go outside immediately and call 112.
• Do not re-enter the premises until the alarm has been stopped and the source of the leak has been dealt with by an expert.

CAUTION
Unlike a smoke detector, a carbon monoxide detector does not easily give false alarms. If the CO Alarm goes off, take it seriously and assume that there is an excessive concentration of CO somewhere.

Installing the detector

Package content

Check the contents of the package against the list below. If the detector is damaged or a part is missing, please contact the supplier

Table 7-1 Checklist

Installation position

In which room should the detector be installed?
Preferably install a carbon monoxide detector in every room with a combustion appliance. For added safety, also install detectors in living rooms and bedrooms. Make sure you can always hear the detector when it sounds the alarm.

Where in the room should the detector be installed?

• Install in a bedroom without a combustion device.
  ◊ Install the alarm at the occupants’ breathing height.
  ◊ Never install the alarm on or near the floor. Carbon monoxide mixes with air and will therefore rarely travel to the floor.

Figure 7-1 Installation in a bedroom without a fuel appliance.

• Install in a living room with a combustion device (stove, boiler, fireplace, gas fire).
  ◊ Install the alarm above the combustion device. Carbon monoxide rises to the surface due to the hot gases from the combustion device.
