Sources of Carbon Monoxide at Home
CO is created by the incomplete combustion of any fossil fuel and can originate from malfunctioning appliances including
furnaces, stoves, ovens and water heaters - that are operated by burning fossil fuels such as natural or liquefied petroleum (LP)
gas, oil, wood, or coal, etc. When malfunctioning appliances are not adequately ventilated, the amount of CO in the air may
rise to a level that can cause illness or even DEATH!

potential sources of CO
Guard Against Carbon Monoxide Poisoning:
CARBON MONOXIDE is a leading cause of unintentional poisoning deaths. Due to today's more energy efficient homes, the
first line of defense is to have your home heating systems, fuel burning appliances, flues and chimneys checked regularly. In
addition, install at least one S-TECH Carbon Monoxide Alarm near sleeping areas. For extra protection, place a CO
Alarm near any area where the CO may be produced.
Installation of Carbon Monoxide Alarm:
The density of Carbon Monoxide at 20 °C (68 °C) is 0.96716 which is slightly lighter than the density of air (1.00). However, at 0
°C or 32 °F the density is increased to 1.250 which is much heavier than air. Practically speaking, placing the CO Alarm
high or low is not a major concern at room temperature. CO permeates a room much like the scent of perfume dispersing
uniformly in all directions and in effect engulfs a room. Install your CO Alarm within 40 ft of
all rooms used for sleeping purposes.
A Reliable Carbon Monoxide Alarm:
Be sure that you only purchase a CO Alarm which is tested, listed and labelled with the UL2034 standard for residential
Carbon Monoxide Alarm as recommended by The Consumer Product Safety Commission (CPSC). An S-TECH CO
Alarm will not confuse you unnecessarily with false alarms because of over sensitivity, or endanger your life because of a
slow response. S-TECH CO Alarms are manufactured employing a reliable engineering design, top quality components &
stringent quality controls. This results in a highly accurate and reliable product. Our units are tested in the presence of CO before being shipped from our factory.
Carbon Monoxide Alarm Rating By A Consumer Evaluation Group:
S-TECH Carbon Monoxide Alarms have been tested by a consumer evaluation group in North America together with
other CO Alarms in the market. S-TECH has been highly recommended and rated amongst the TOP THREE in three
consecutive years, from 1996 to 1998.
