Alarm/Danger Levels - Kidde KN-OOB-B User Manual

Alarm/Danger Levels

Caution: This CO alarm will only indicate the presence of
CO at the sensor. CO may be present in other areas.
Mild Exposure: Headaches, running nose, sore eyes,
often described as "flu-like" symptoms.
Medium Exposure: Dizziness, drowsiness, vomiting.
Extreme Exposure: Unconsciousness, brain damage,
death.
Familiarization with the effects of each level is important.
The symptoms described in the chart above are related to car-
bon monoxide poisoning and should be discussed with ALL
members of the household.
Exposure to high levels of carbon monoxide can be
fatal or cause permanent damage and disabilities.
Many victims of carbon monoxide poisoning indicate that
while they were aware that they were ill, they became so dis-
oriented and confused that they were unable to help them-
selves by exiting the building or calling for assistance. If you
experience any symptoms of carbon monoxide poisoning, con-
sult your doctor immediately! CO poisoning can be deter-
mined by a simple blood test called a carboxyhemoglobin test.
Severe cases may require treatment in a hyperbaric chamber.
Remember, young children and household pets may be the
first effected.
If you have additional questions please call the Kidde
Consumer Hotline at 1-800-880-6788.
