When the carbon monoxide alarm sounds:

Based on recommendations from EN 50292, follow these
steps if alarm sounds ( 4 loud audible pulses followed by
a pause for 5 seconds)

1. Keep calm and open all doors and windows. Turn
off all fuelburning appliances if possible. Note: it is
possible that outdoor conditions could influence
domestic CO alarms (bad traffic pollution in cold
weather, for example). In these circumstances, the
level of indoor CO might actually increase when
doors and windows are opened.

2. If the alarm continues to sound, even after being
reset (where appropriate), then evacuate the
premises, alerting other occupants to the risk. Leave
doors and windows open. Do not re-enter the
premises.

3. Get medical help for anyone suffering the effects of
CO poisoning, and advise that CO inhalation is sus­pected.

4. Call Gas Emergency Services: 0800 111 999, or your
local Gas Safe Registered Engineer:

Never restart the source of a CO problem until it has
been corrected. Never ignore the sound of the alarm!
Pressing the test/reset button will silence the alarm. If
the CO condition that caused the alert continues, the
alarm will reactivate. If the unit alarms again within
six minutes, it is sensing high levels of CO which can
quickly become a dangerous situation.

WARNING:

Actuation of your CO Alarm
indicates the presence of
Carbon Monoxide (CO)
which can kill you.

What To Do When The Alarm Sounds!

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 2

NEVER IGNORE THE SOUND OF THE ALARM!

Determining what type of alarm has sounded is easy with
your Kidde Combination Smoke/CO Alarm. The voice
message warning system will inform you of the type of
situation occurring. Refer to the Features section on page 4
for a detailed description of each alarm pattern.

When the smoke alarm sounds:

Smoke alarms are designed to minimize false alarms.
Cigarette smoke will not normally set off the alarm, unless
the smoke is blown directly into the alarm. This unit
contains nuisance alarm protection, which will reduce the
impact of cooking particles. However, large quantities of
combustible particles from spills or grilling could still cause
the unit to alarm. Careful location of the unit away from
the kitchen area will give the maximum nuisance alarm
protection. Combustion particles from cooking may set off
the alarm if located too close to the cooking area. Large
quantities of combustible particles are generated from spills
or when broiling. Using the fan on a range hood which
vents to the outside (non- recirculating type) will also help
remove these combustible products from the kitchen.

If the alarm sounds, check for fires first. If a fire is
discovered follow these steps. Become thoroughly familiar
with these items, and review with all family members!

• Alert small children in the home. Children sleep very
soundly and may not be awakened by the sound of
the smoke alarms.

• Leave immediately using one of your planned escape
routes (see page 21). Every second counts, don’t stop
to get dressed or pick up valuables.

• Before opening inside doors look for smoke seeping in
around the edges, and feel with the back of your hand.
If the door is hot use your second exit. If you feel it’s
safe, open the door very slowly and be prepared to
close it immediately if smoke and heat rush in.

• If the escape route requires you to go through smoke,
crawl low under the smoke where the air is clearer.

What To Do When The Alarm Sounds!

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 3

What To Do When The Alarm Sounds!

• Go to your predetermined meeting place. When two
people have arrived one should leave to call 999 from
a neighbour's home, and the other should stay to
perform a head count.

• Do not re-enter under any circumstance until fire
officials give the go ahead.

•

There are situations where a smoke alarm may
not be effective to protect against fire. For example;

- Smoking in bed.

- Leaving children unsupervised.

- Cleaning with flammable liquids, such as

gasoline.

- Fires where the victim is intimate with a flaming

initiated fire; for example, when a person's
clothes catch fire while cooking.

- Fires where the smoke is prevented from

reaching the detector due to a closed door or
other obstruction.

- Incendiary fires where the fire grows so rapidly

that an occupant's egress is blocked even with
properly located detectors.

Independent smoke and carbon monoxide sensors

.

• Smoke alarm takes precedence when both smoke and
carbon monoxide are present.

• Alarm/Voice message warning system that alerts you of the
following conditions in the manner described below, thus
eliminating any confusion over which alarm is sounding:

o FIRE: The alarm/voice pattern is three long alarm beeps

followed by the verbal warning message “FIRE! FIRE!”.
This pattern is repeated until the smoke is eliminated. The
red LED light will flash while in alarm/voice mode.

o CARBON MONOXIDE: The alarm/voice pattern is four short

alarm beeps followed by the verbal warning message
“WARNING! CARBON MONOXIDE!”. After four minutes
the alarm/voice pattern will sound once every minute until
the unit is reset, or the CO eliminated. The red LED light
will flash while in alarm/voice mode.

o LOW BATTERY: This alarm has a low battery pre-warning.

The red LED will flash every 60 seconds for a period of 28
days. Following this pre-warning, when the battery is low
and needs replacing, the red LED will flash and the unit
will "chirp" one time, followed by the warning message
"LOW BATTERY". This cycle will occur once every minute
for the first hour. After the first hour the red LED light will
continue to flash every minute accompanied by the
“chirp” only sound. The voice message “LOW BATTERY”
will sound once every fifteen minutes during the “chirp”
only cycle. This will continue for at least seven days.

• Voice Message System that alerts user to the following
conditions:

o System announces “HUSH MODE ACTIVATED” when the

unit is first put into HUSH Mode.

o System announces “HUSH MODE CANCELLED” when unit

resumes normal operation after Hush Mode has been
cancelled.

o System announces “CAUTION, CARBON MONOXIDE

PREVIOUSLY DETECTED” when the unit has detected CO
concentrations of 100 ppm or higher.

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 10

Smoke Alarm

The smoke alarm monitors the air for products of
combustion that are produced when something is burning
or smouldering. When smoke particles in the smoke sensor
reach a specified concentration, the alarm/voice message
warning system will sound, and be accompanied by the
flashing red LED light. The smoke alarm takes

precedence when both smoke and carbon monoxide
are present.

Life safety from fire in residential occupancies is based
primarily on early notification to occupants of the need to
escape, followed by the appropriate escape actions by those
occupants. Fire warning systems for dwelling units are
capable of protecting about half of the occupants in
potentially fatal fires. Victims are often intimate with the
fire, too old or too young, physically or mentally impaired
such that they cannot escape even when warned early
enough that escape should be possible. For these people,
other strategies such as protection-in-place or assisted
escape or rescue are necessary.

• Smoke alarms are devices that can provide early warning
of possible fires at a reasonable cost; however, alarms
have sensing limitations. Ionisation sensing alarms may
detect invisible fire particles (associated with fast flaming
fires) sooner than photoelectric alarms. Photoelectric
sensing alarms may detect visible fire particles (associated
with slow smouldering fires) sooner than ionisation
alarms. Home fires develop in different ways and are
often unpredictable. For maximum protection, Kidde
recommends that both Ionisation and Photoelectric
alarms be installed.

• A battery-powered alarm must have a battery of the
specified type, in good condition and installed properly.

• Smoke alarms must be tested regularly to make sure the
batteries and the alarm circuits are in good operating
condition.

• Smoke alarms cannot provide an alarm if smoke does not
reach the alarm. Therefore, smoke alarms may not sense
fires starting in chimneys, walls, on roofs, on the other
side of a closed door or on a different floor.

Smoke Alarm Features

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 11

• If the alarm is located outside the bedroom or on a
different floor, it may not wake up a sound sleeper.

• The use of alcohol or drugs may also impair one’s ability
to hear the smoke alarm. For maximum protection, a
smoke alarm should be installed in each sleeping area on
every level of a home.

• Although smoke alarms can help save lives by providing
an early warning of a fire, they are not a substitute for an
insurance policy. Home owners and renters should have
adequate insurance to protect their lives and property.

Carbon Monoxide (CO) Alarm

The carbon monoxide (CO) alarm monitors the air for the
presence of CO. It will alarm when there are high levels of
CO present, and when there are low levels of CO present
over a longer period of time. When a CO condition
matches either of these situations, the alarm/voice message
warning system will sound, and be accompanied by the
flashing red LED light. The carbon monoxide sensor uses an
electrochemical technology.

CAUTION: This alarm will only indicate the
presence of carbon monoxide gas at the sensor.
Carbon monoxide gas may be present in other areas.

Warning: The device cannot warn against the
chronic effects of exposure to carbon monoxide or
protect individuals who are at specific risk.

Individuals with medical problems may consider using
warning devices which provide audible and visual signals for
carbon monoxide concentrations less than 30 ppm.

This alarm must only be installed by a
competent person

Step 1
Installation Guide:

IMPORTANT: THIS ALARM MUST BE MOUNTED ON A
CEILING OR WALL. IT WAS NOT DESIGNED FOR USE AS A
TABLETOP DEVICE! INSTALL
ONLY AS DETAILED!

A. Recommended
Installation Locations:

Kidde recommends the instal­lation of a Smoke/CO Alarm
in the following locations. For
maximum protection we sug­gest an alarm be installed on
each level of a multilevel
home, including

every bed­room, hallways, finished attics
and basements.

If installing
this alarm in the kitchen,
please note that sometimes
cooking fumes or steam can result in 'nuisance' smoke
alarms which can be minimized by locating the alarm away
from sources of cooking fumes or steam. Put alarms at both
ends of bedroom, hallway or large room if hallway or room is
more than 30 ft (9.1m) long. If you have only one alarm,
ensure it is placed in the hallway outside of the main sleeping
area, or in the main bedroom. Verify the alarm can be heard
in all sleeping areas.

Locate an alarm in every room where someone sleeps with
the door closed. The closed door may prevent an alarm not
located in that room from waking the sleeper. Smoke, heat
and combustion products rise to the ceiling and spread
horizontally.

Mounting the alarm on the ceiling in the centre of the room
places it closest to all points in the room. Ceiling mounting is
preferred in ordinary residential construction. When mounting an
alarm on the ceiling, locate it at a minimum of 12" (30.5 cm)
from the side wall (see figure 1). If installing the alarm on the
wall, use an inside wall with the top edge of the alarm at a
minimum of 6" (15cm) and a maximum of 12” (30.5cm) below
the ceiling (see figure 1).

Sloped Ceiling Installation:

Install within 0.9m of the highest point (measured
horizontally). Smoke alarms in rooms with ceiling slopes
greater than 0.3m in 2.4m horizontally shall be located on
the high side of the room. A row of detectors shall be
spaced and located within 0.9m of the peak of the ceiling
measured horizontally (see Figure 2)

Static Mobile Homes:

Modern mobile homes have been designed and built to be
energy efficient. Install Smoke/CO alarms as recommended
previously (refer to Recommended Installation Instructions
and figure 1). In older mobile homes that are not well
insulated, extreme heat or cold can be transferred from the
outside to the inside through poorly insulated walls and
roof. This may cause a thermal barrier, which can prevent
smoke from reaching an alarm mounted on the ceiling. In
such mobile homes install your Smoke/CO Alarm on an
inside wall with the top edge of the alarm at a minimum of
6 inches (15cm) and a maximum of 12 inches (30.5cm)
below the ceiling (See figure 1). If you are not sure about
the insulation in your mobile home, or if you notice that the
outer walls and ceiling are either hot or cold, install your
alarm on an inside wall ONLY!

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 14

Step 2: Mounting Instructions

CAUTION: YOUR SMOKE/CO ALARM IS SEALED

AND THE COVER IS NOT REMOVABLE!

1. To help identify the date to replace the unit, a label has
been affixed to the side of the alarm. Write the “Replace
by” date (10 years from initial power up) in permanent
marker on the label. See Alarm Replacement section for
additional information.

2. Remove the mounting bracket from the back of the alarm
by holding the mounting bracket and twisting the alarm in
the direction indicated by the “OFF”arrow on the alarm
cover.

3. Select the proper location for your Smoke/CO Alarm, as
described on Pages 8-11. To ensure aesthetic alignment of
the alarm with the hallway, or wall, the “A” line on the
mounting bracket must be parallel with the hallway when
ceiling mounted, or horizontal when wall mounted.

4. Install the alarm on the mounting bracket and rotate the
alarm in the direction of the “ON” arrow on the cover
until the alarm ratchets into place (this ratcheting function
allows for aesthetic alignment). Note: The alarm will
mount to the bracket in 4 positions (every 90 degrees).

B. Where Not to Install:
Do not install in garages, furnace rooms or bath-

rooms! INSTALL AT LEAST 5 FEET AWAY FROM ANY
FUEL BURNING OR COOKING APPLIANCE

• Don’t install within 1 metre of fuel burning appliances

• Don’t wall-mount close to obstructions (e.g. behind
curtains, shelving or furniture)

• Don’t fit in dusty, dirty or greasy areas (e.g. garages or
workshops)

• Avoid humid areas (such as bathrooms) with greater
than 90% relative humidity (RH), non-condensing, or
areas with temperatures outside of the operating range
(0-40C). Keep away from sinks.

• Don't install within 1 metre of fluorescent lights

Two labels are included with your alarm. They have
important information on what to do in case of an alarm.
Add the phone number of your emergency service
provider (for smoke or fire emergencies call '999' or for
CO gas emergencies call 0800 111 999) in the space
provided. Alternatively, for solid fuel emergencies call
HETAS (0845 634 5626) or for oil based emergencies call
Oftec (0845 658 5080). Place one label next to the alarm
after it is mounted, and one label near a fresh air source
such as a door or win

dow.

6. Pull the Battery Pull Tab (yellow tab protruding from unit)
completely out of unit. This will automatically connect
the battery.

Step 3: Testing the Alarm

CAUTION: Due to the loudness (85 decibels) of the
alarm, always stand an arms length away from the
unit when testing.

The test/reset button has four purposes. It tests the unit’s
electronics, resets the CO alarm, activates the HUSH
feature, and activates the Peak Level Memory Feature.

After installation, TEST THE UNIT’S ELECTRONICS by
pressing and releasing the test/reset button. A series of
beeps will sound, followed by the message “Fire! Fire!”
then another two series of beeps and the message
“WARNING! CARBON MONOXIDE!” followed by 4
additional short beeps.

Weekly testing is required! If at anytime it does not perform
as described, verify that the battery doesn’t need replacing.
Clean dust and other buildup off the unit. If it still doesn’t
operate properly call the Consumer Hotline at 0800 917

0722.

HUSH®Control Feature

The HUSH®feature has the capability of temporarily
desensitizing the smoke alarm circuit for approximately 10
minutes. This feature is to be used only when a known
alarm condition, such as smoke from cooking, activates the
alarm. You can put your Smoke/CO Alarm in HUSH®mode
by pushing the test/reset button. If the smoke is not too
dense, the alarm will silence immediately, the unit will
verbally announce “HUSH MODE ACTIVATED”, and the

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 16

12

Operating and Installation Instructions

green LED will flash every 2 seconds for approximately 10
minutes. This indicates that the smoke alarm is in a temporari­ly desensitized condition. Your Smoke/CO Alarm will
automatically reset after approximately 10 minutes. When the
unit returns to normal operation after being in HUSH®mode,
it will verbally announce “HUSH MODE CANCELLED”, and
sound the alarm if smoke is still present. The HUSH®feature
can be used repeatedly until the air has been cleared of the
condition causing the alarm. While the unit is in HUSH

®

mode, pushing the test/reset button on the alarm will also
end the HUSH®period.

NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH

®

CONTROL FEATURE AND SOUND A CONTINUOUS ALARM.

CAUTION: BEFORE USING THE ALARM HUSH

®

FEATURE, IDENTIFY THE SOURCE OF THE SMOKE AND BE
CERTAIN A SAFE CONDITION EXISTS.

Reset Feature

If the Smoke/CO Alarm is sounding a CO alarm, pressing the
test/reset button will initiate a test/reset. If the CO condition
that caused the alert continues, the alarm will reactivate.

Alarm/Peak Level Memory

If the green LED is blinking once every 16 seconds, the unit
has detected a hazardous condition. If the unit has detected
a CO level of 100 PPM or greater, pushing the Test/Reset
button will result in a voice message “Caution, carbon
monoxide previously detected”. Peak level also happens if
the unit detects smoke and then comes out of alarm.
However, there is no voice message if the unit is in peak level
due to smoke. When the Test/Reset button is pushed, the
unit will produce three rapid beeps. Pushing the test/reset
button resets the memory. It’s also reset when the power is
removed.

LED Indicator Operation
Red LED

The red LED will flash in conjunction with the alarm
sounder. Therefore, the red LED will flash during a smoke
alarm, a CO alarm, a low battery mode chirp and a unit
error mode chirp.

Green LED

The green LED will flash as described below under the

following conditions:

– Standby Condition: The LED will flash every 30

seconds.

– Alarm Condition: The LED will flash every second

signifying that the alarm sensed a smoke or CO
hazard.

– HUSH MODE Condition: The LED will flash every 2

seconds while the alarm is in HUSH mode.

– Alarm Memory: The LED blinks once every 16 seconds

to indicate a hazardous condition was previously
detected.

Tamper-Resist Features

Two Tamper-Resist features have been provided. The first is
used to discourage removal of the alarm while the second is
for the battery. To activate the mounting bracket
Tamper-Resist feature break off the four posts in the square
holes in the trim ring (see figure 5A). When the posts are
broken off, the Tamper-Resist tab on the base is allowed to
engage the mounting bracket. Rotate the alarm onto the
mounting bracket until you hear the Tamper-Resist tab snap
into place, locking the alarm on the mounting bracket.
Using the Tamper-Resist feature will help deter children and
others from removing the alarm from bracket.

NOTE: To remove the alarm when the Tamper-Resist tab is
engaged, press down on the Tamper-Resist tab, and rotate
the alarm off of the bracket (see figure 5B).

This alarm also has a battery carrier Tamper-Resist feature,
which helps prevent the battery carrier from being opened.
This feature is effective in preventing the removal of the
battery from this device.

To activate the battery carrier Tamper-Resist feature, remove
the unit from the trim and locate the small cut-out in the
middle of the product label on
the back of the unit. With a
small screwdriver, or similar tool,
slide the switch towards the top
of the label. (see Figure 6) The
Tamper-Resist feature is now

CO Alarm Response Time

Never restart the source of a CO problem until it has
been fixed. NEVER IGNORE THE ALARM!

The CO sensor meets the alarm response time requirements of
EN50291-1:2010. Standard alarm times are as follows:

This carbon monoxide alarm is designed to detect
carbon monoxide gas from ANY source of combustion.
It is NOT designed to detect any other gas.

It can be possible to arrange for a CO inspection of your
home or property, but some inspectors may charge for this
service. Kidde will not pay for or reimburse the owner or
user of this product for any repair or dispatch calls related
to the alarm sounding so it is advisable to inquire about

Remove the alarm from the mounting bracket by rotating
the alarm in the direction of the “OFF” arrow on the cover.

If any form of battery failure is detected the red LED light will
flash and the unit will “chirp” one time, followed by the
warning message “LOW BATTERY”. This cycle will occur once
every minute for the first hour. After the first hour, the red LED
light will continue flashing accompanied by the chirp only
sound every 60 seconds. The voice message “LOW BATTERY”
will sound once every fifteen minutes during the chirp only
cycle, and will continue for at least seven days.

If the red LED light flashes along with a chirp every 30
seconds, and is not followed by the voice message
“LOW BATTERY” as described above, your unit has
malfunctioned. Call our toll-free Consumer Hotline at

through the openings around the perimeter of the alarm.
If cleaning does not restore your alarm to normal
operation the alarm should be replaced.

REINSTALL IMMEDIATELY AFTER CLEANING AND THEN TEST
USING THE TEST/RESET BUTTON! IF TAMPER-RESIST
FEATURE HAS BEEN ACTIVATED, REFER TO TAMPER-RESIST
FEATURE DESCRIPTION ON PAGES 13-14 FOR REMOVAL
INSTRUCTIONS.

• Never use detergent or other solvents to clean the unit.

• Avoid spraying air freshener, hair spray, or other aerosols
near the Smoke/CO Alarm.

Do not paint the unit. Paint will seal the vents and interfere
with the sensor’s ability to detect smoke and CO. Never
attempt to disassemble the unit or clean inside. This action
will void your warranty. Move the Smoke/CO Alarm and
place in another location prior to performing any of the
following:

• Staining or stripping wood floors or furniture

• Painting

• Wall papering

• Using adhesives

Storing the unit in a plastic bag during any of the above
projects will protect the sensors from damage. Do not place
near a nappy bin.

WARNING: Reinstall the Smoke/CO Alarm as soon as

possible to assure continuous protection.

When household cleaning supplies or similar contaminates
are used, the area must be well ventilated. The following
substances can affect the CO sensor and may cause false
readings and damage to the sensor: Methane, propane,
iso-butane, iso-propanol, ethyl acetate, hydrogen sulfide,
sulfide dioxides, alcohol based products, paints, thinner,
solvents, adhesives, hair spray, after shave, perfume, and
some cleaning agents.

NOTE: there could be other compounds occurring
within a particular household which could cause
similar effects.

General CO Information

Carbon Monoxide (CO) is a colourless, odourless, and
tasteless poison gas that can be fatal when inhaled. CO
inhibits the blood’s capacity to carry oxygen.

Possible Sources

CO can be produced when burning any fossil fuel: petrol,
diesel, propane, natural gas, oil and wood. It can be produced
by any fuel-burning appliance that is malfunctioning,
improperly installed, or not ventilated correctly. Possible sources
include boilers, gas range/stoves, high concentrations of tobac­co smoke, gas clothes dryers, water heaters, portable fuel
burning space heaters, fireplaces, wood-burning stoves
and certain swimming pool heaters. Blocked chimneys or
flues, back drafting and changes in air pressure, corroded or
disconnected vent pipes, can also cause CO. Vehicles and other
combustion engines running in an attached garage and using
a charcoal/gas grill or barbecue in an enclosed area are all
possible sources of CO. Do not BBQ in enclosed spaces.

The following conditions can result in transient CO situations:
Excessive spillage or reverse venting of fuel-burning appliances

caused by outdoor ambient conditions such as: Wind direction
and/or velocity, including high gusts of wind, heavy air in the
vent pipes (cold/humid air with extended periods between
cycles), negative pressure differential resulting from the use of
exhaust fans, simultaneous operation of several fuel-burning
appliances competing for limited internal air, vent pipe
connections vibrating loose from clothes dryers, boilers, or
water heaters, obstructions in, or unconventional, vent pipe
designs which can amplify the above situations, extended
operation of unvented fuel-burning devices (range, oven,
fireplace, etc.), temperature inversions which can trap exhaust
gases near the ground, car idling in an open or closed attached
garage, or near a home.

NOTE: The apparatus may respond to brief exhaust gas
emissions, for example during the initial start-up of an
appliance. Also, hydrogen acts as an interferent and can
arise from some battery charging activities and the curing
of concrete or cement under certain circumstances.
Volatile Organic Compounds (VOCs), e.g. alcohols, which
may eventually activate the alarm, can be generated from
use of damp-proofing materials or other coatings contain­ing alkylalkoxysilanes.

Carbon Monoxide Safety Information

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 24

CO Safety Tips

Every year, have the heating system, vents, chimney and
flue inspected and cleaned by a qualified technician. Always
install appliances according to manufacturer’s instructions
and adhere to local building regulations. Most appliances
should be installed by professionals and inspected after
installation. Regularly examine vents and chimneys for
improper connections, visible rust, or stains, and check for
cracks in furnace heat exchangers. If at any time you
discover any faults, contact a qualified technician. Verify the
colour of flame on pilot lights and burners is blue. A yellow
or orange flame is a sign that the fuel is not burning
completely. Teach all household members what the alarm
sounds like and how to respond.

Symptoms of CO Poisoning

Initial carbon monoxide poisoning symptoms are similar to the
flu with no fever and can include dizziness, severe headaches,
nausea, vomiting and disorientation. Everyone is susceptible
but experts agree that unborn babies, pregnant women, senior
citizens and people with heart or respiratory problems are
especially vulnerable. If symptoms of carbon monoxide
poisoning are experienced seek medical attention immediately.
CO poisoning can be determined by a carboxyhemoglobin test.

The following symptoms are related to CARBON MONOXIDE
POISONING and should be discussed with ALL members of the
household:

2540-7205-04_10SCO(KN-COPE-D)_V1.qxd:_ 2015.11.2 3:10 PM Page 25

The above levels of exposure relate to healthy adults. Levels
differ for those at high risk. Exposure to high levels of carbon
monoxide can be fatal or cause permanent damage and
disabilities. Many cases of reported carbon monoxide
poisoning indicate that while victims are aware they are not
well, they become so disoriented they are unable to save
themselves by either exiting the building, or calling for
assistance. Also, young children and household pets may be
the first affected. Familiarisation with the effects of each level
is important.

Escape Plan

Prepare and practice a home escape plan twice a year,
including drills at night. Know two ways out of every room
(door & window) and identify a meeting
place outside the home where everyone
will gather once they have exited the
residence. When two people have
reached the meeting place, one should
leave to call 999 while the second per­son stays to account for additional fami­ly members.

Establish a rule that once you’re out,
you never re-enter under any cir­cumstance!

Fire Prevention

Never smoke in bed, or leave cooking food unattended. Teach
children never to play with matches or lighters! Train everyone
in the home to recognize the alarm pattern, voice message
warning and to leave the home using their escape plan when
it’s heard. Know how to do “Stop, Drop and Roll” if clothes
catch on fire, and how to crawl low under smoke. Install and
maintain fire extinguishers on every level of the home and in
the kitchen, basement and garage. Know how to use a fire
extinguisher prior to an emergency. Second level and higher
occupied rooms with windows, should have an escape ladder.

Fire Safety Information

Current studies have shown smoke alarms may not awaken all
sleeping individuals, and that it is the responsibility of
individuals in the household that are capable of assisting others
to provide assistance to those who may not be awakened by
the alarm sound, or to those who may be incapable of safely
evacuating the area unassisted.
