b. Negative pressure differential resulting from the use of exhaust fans.

c. Simultaneous operation of several fuel burning appliances competing for lim-

ited internal air.

d. Vent pipe connection vibrating loose from clothes dryers, furnaces, or water

heaters.

e. Obstructions in unconventional vent pipe designs which amplify the above situ-

ation.

2. Extended operation of unventilated fuel burning devices (oven, fireplace, etc).

3. Temperature inversions which can trap exhaust gases near the ground.

4. Car idling in an open or closed attached garage, or near a home.

Possible Symptoms of Carbon Monoxide Poisoning

Carbon monoxide is colorless, odorless, tasteless, and very toxic. When inhaled, it pro-

duces an effect known as chemical asphyxiation. Injury is due to the combining of CO

with the available hemoglobin in the blood, lowering the oxygen- carrying capacity of

the blood. In the presence of CO gas, the body is quickly affected by oxygen star-

vation. The following symptoms are related to CO poisoning and should be discussed

with all members of the household:

a. Mild exposure: slight headache, nausea, vomiting, fatigue (often described as

"flu-like" symptoms).

b. Medium exposure: severe throbbing headache, drowsiness, confusion, fast heart

rate

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

d. 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.

Young children and household pets are typically the first affected.

Action to Take When Alarm Sounds

If harmful levels of CO gas are detected, your detector will go into continuous full

alarm. Try to take the following necessary actions immediately:

1. Push the detector Test/Hush switch to silence the alarm. Warning: Never remove

the battery to silence the alarm. Removing the battery removes your protection!

Pushing the Test/Hush button mutes the alarm for 5 minutes. After 5 minutes, the

alarm resumes if CO levels remain high.

Call your emergency service. Please write down the telephone numbers:

Emergency Services:

Tel. No. .................................

2. Immediately move to fresh air - outdoors or by opening door/window. Do a head

count to check that all persons are accounted for. Do not reenter the premises nor

move away from the open door/window until the emergency services responders

have arrived, the premises have been aired out, and your alarm remains in nor-

mal condition.

3. After following steps 1 - 3, if your alarm reactivates within a 24-hour period,

repeat steps 1 - 3 and call a qualified technician (Tel. No. ........................) to

investigate for sources of CO gas from fuel burning equipment and appliances,

and inspect for proper operation of this equipment. If problems are identified dur-

ing this inspection, have the equipment serviced immediately. Note any com-

bustion equipment not inspected by the technician and consult the manufacturer

instructions, or contact the manufacturers directly, for more information about

CO safety and this equipment. Make sure that motor vehicles are not, and have

not been, operating in an attached garage or adjacent to the residence.

WARNING: CO gas can be extremely fatal and can come from several possible

sources. This detector only indicates the presence of CO gas near the sensor. CO

gas may be present in other areas of the premises.

Action to be Taken After the Problem has been Corrected

Once the CO gas presence in the premises has been corrected, the detector's alarm

should be off. After waiting for 10 minutes, push the Test/Hush button to verify that

the detector is functioning properly.
