3. WHAT IS CARBON MONOXIDE
Carbon Monoxide (CO) is an insidious poison that is released when fuels
are burnt. It is a colourless, odourless, tasteless gas and thereforevery
dicultto detectwith the human senses. COkills hundreds of people
each yearand injures many more. It bindsto the hemoglobin inthe
blood and reducesthe amountof oxygen being circulated inthe body. In
high concentrations,CO can kill in minutes. CO is producedby the
incomplete combustion offuels such as wood, charcoal, coal, heating oil,
paran, petrol, naturalgas, propane,butane etc.
Examples of COsources:
Running engine in garage -Gas appliances
Oil and Gas furnaces -Portable generators
Woodstoves -Gas or kerosene heaters
Barbecues Clogged chimneys
Woodand gas replaces Heating boiler
4. SYMPTOMS OF CO POISONING
The following symptoms maybe related to CO poisoning:
35 ppm The maximum allowable concentrationfor continuous
exposurefor healthy adults in any 8 hour period.
200ppm Slight headaches, fatigue, dizziness, nausea aer 2-3 hours
400ppm Frontalheadaches within 1-2 hours, lifethreatening aer 3
hours
800ppm Dizziness, nausea and convulsions within 45 minutes.
Unconsciousnesswithin 2 hours, Death within 3 hours.
1600ppm Headache, dizziness and nausea within 20 minutes. Death
within 1 hour
6400ppm Headache, dizziness and nausea within 1-2 minutes.
WARNING: The apparatus may not preventthe chronic eects of
carbon monoxide exposure,and that the apparatus will not fully
safeguardindividuals at special risk. It maynot fully safeguard
individuals with specic medical conditions.If in doubt, consult a medical
practitioner.
5. LOCATING THE CO ALARM
C11-L Carbon Monoxidealarm is designedto detectthe toxic COfumes
that resultfrom incomplete combustion, such as those emitted from
appliances,furnaces, replace and auto exhaust.
NOTE:For maximum protection an alarm should be tted in ornear
everyroom that contains afuel-burning appliancesuch as anygas res,
central heating boilers, room
heaters, waterheaters, cookers, grills, etc.
WARNING:Thisalarm will only indicate the presence ofcarbon
monoxide gas atthe sensor. Carbon monoxidegas maybe present in
otherareas.
A CARBON MONOXIDE ALARM DOES NOT FUNCTION AS A
REPLACEMENT FOR A SMOKE OR GAS DETECTOR.
6. Location of the carbon monoxide detector
6.1 General
The design and layout of domestic premises and the number, type and
position of carbon monoxide sourcesvarywidely. However, general
guidance is given on where and wherenot to locate the apparatus in
orderto minimise the risk of misleading indications.
6.2 Which room?
Ideally, an apparatus should be installed in everyroom containing a fuel-
burning appliance.Additional apparatusmay be installed to ensure that
adequate warning is given foroccupants in other rooms, bylocating
apparatus in:
• remote rooms in which the occupant(s) spend considerable timewhilst
awakeand from which theymay not be able hear an alarm from
apparatus in another part ofthe premises and
• everysleeping room
• However,if there is a fuel burning appliance in more than one room an
the number of apparatusis limited,the following points should be
consideredwhen deciding where best to put the apparatus:
• locate the apparatus in a room containing a ueless or open-ued
appliance, and
• locate apparatus in a room wherethe occupant(s)spend most time.
Ifthe domestic premisesis a bedsit(a single room serving as both sitting
and bedroom) thenthe apparatusshould be put as farfromthe cooking
appliances as possible bue near to wherethe person sleeps.
Ifthe appliance is in a room notnormally used (forexample a boiler
room),the apparatusshould be put just outside the room sothat the
alarm may be heard moreeasily.Alternatively,a remote alarm siren may
be connected to a typeA apparatus located in a room(s) containing a
fuel-burning appliance.
6.3 Where in the room?
It should be possible to view all the light indicators when in thevicinity
ofthe chosen locationforthe apparatus.
It is not possible to give specic guidance on the exact location of a
detectorwhich suits alltypes of room and their usage.The following
points should be taken into considerationwhen determining an
optimum location forany appropriate situation.
6.3.1 Where not to install the apparatus
The apparatus should not be installed:
• inan enclosed space(forexample in a cupboardor behind a curtain)
• where it can be obstructed (forexample by furniture)
• directly above a sink
• next to a door orwindow
• next to an extractorfan
• next to an airvent or other similarventilation openings
• inan area wherethe temperature maydrop below -10 °C or exceed
40 °C, unless it is designedto do so
• where dirt an dust mayblock the sensor
• ina damp orhumid location
• inthe immediate vicinity ofthe cooking appliance
6.3.2 Apparatus located in the same room as a fuel-burning
appliance
Ifthe apparatus is locatedon awall:
a)it should be located closeto the ceiling;
b) it should be located at a height greaterthan the height of any door or
window.
A ceilingmounted apparatusshould be at least 300 mm fromany wall,
and fora wall mounted apparatus it should be at least 150 mm fromthe
ceiling.The apparatus should be at a horizontal distance ofbetween 1m
and 3 m fromthe potentialsource.
Ifthere is a partition in a room,the apparatus should be located onthe
same side of the partition as the potential source.
Carbon Monoxide alarms in rooms with sloped ceilings should be
located atthe high side ofthe room.
