Carbon monoxide (CO) is a highly toxic gas released when
fuels are burned. It is colourless and odourless and is,
therefore, very difficult for human senses to perceive. The first
warning symptoms of the presence of CO in the air are usually
headaches and nausea.
Fatigue, headaches, dizziness, nausea, general
pains in the chest or stomach area
carbon monoxide binds the haemoglobin in the blood which
reduces the oxygen transported in the body. Highly
concentrated CO leads to death within minutes.
35 ppm
The highest permissible CO value over a period
of 8 hours
200 ppm
Light headache, fatigue, dizziness, nausea
after 2 to 3 hours
Danger!
If this point is not heeded, life, health and
property are endangered.
Do not leave small children unsupervised with the
product, packaging material or small parts. Otherwise
there is a risk of fatal injury due to choking!
Do not damage any gas, electricity, water or
telecommunication lines during drilling and fixing work.
Otherwise there are dangers of personal and fatal injury!

Although feeling unwell, victims of carbon monoxide
poisoning become so disorientated that they can no longer
decide what to do next, including being unable to exit the
building or to call for assistance. Very young children often
show symptoms earlier than adults. Being affected while
asleep is the most dangerous situation as the victim will not
wake as a result.
A hazardous carbon monoxide concentration can be caused
by incomplete combustion of fossil fuels for example solid
fuels (like wood, coal, coke), liquid fuels (like oil or petrol) or
gaseous fuels (like natural, town or liquid (LPG) gas). There
can be several causes of this:
A faulty or poorly maintained heating appliance
Poor ventilation in a room
A chimney or flue is blocked, partly blocked or is leaking
Other sources of carbon monoxide are:
Barbeques or Stoves
Petrol or diesel motors in motorcycles, lawnmowers or
other garden equipment, especially when there are
stored in a garage or shed
Cigarette, cigar or pipe smoke
Incorrectly installed heating appliances
All heating appliances must be regularly serviced by a
qualified specialist.
Ideally, a carbon monoxide alarm should be installed in every
room with a combustion device or where a flue/chimney
passes through.
Additional detectors may be installed to ensure that
adequate warning is given for occupants in other rooms
by locating detectors in remote rooms in which the
occupants spend considerable time whilst awake and
from which they may not be able to hear an alarm signal
from a device in another part of the premises
in every sleeping room
