GENERAL INFORMATION

The SACO-2 Carbon Monoxide Detector monitors the presence of CO

(carbon monoxide) with an electrochemical sensor. It is not influenced by

humidity, natural gas or LPG (liquefied petroleum gas). It will measure the

concentration of CO between 1-999 PPM (parts per million) with a resolu-

tion of 1 PPM and factors in a small zero float. Typical battery life of this

monitor is 500 hours when used with an alkaline battery. This device can

be used by professional technicians and experts to detect CO build up in

industrial and residential environments. It is able to detect CO in living

areas, garage and around gas burner appliances. The detector will only

indicate the presence of carbon monoxide gas at the sensor. Carbon

monoxide may be present in other areas.

The detector indicates the presence of Carbon Monoxide in two ways:

• By displaying a reading in PPM concentrations of carbon monoxide

on the LCD (liquid crystal display).

• By emitting an audible beep when carbon monoxide is present in

excess of 40 PPM.

GENERAL DESCRIPTION OF CARBON MONOXIDE

Carbon Monoxide (CO) is an odorless, colorless gas that is formed as a

result of incomplete combustion of carbon based fuels (wood, coal, gaso-

line, LP Gas, etc.). When fuel is burned Carbon (C) and Oxygen (O) will

normally combine to form Carbon Dioxide (CO

gen, due perhaps to a restricted air flow, CO is formed. Internal combus-

tion engines and propane gas fired appliances are typical sources of car-

bon monoxide.

Actuation of this device indicates the presence of carbon monoxide

(CO) which can be FATAL.

WHEN MONITOR BEEPS:

If anyone has a headache or an upset stomach call the Fire Department immedi-

ately and move to a location which has fresh air. DO A HEAD COUNT TO CHECK

THAT ALL PERSONS ARE ACCOUNTED FOR. DO NOT RE-ENTER PREMISES

UNTIL IT HAS BEEN AIRED OUT AND THE PROBLEM CORRECTED!

If no one exhibits symptoms of discomfort associated with CO poisoning, simply:

• Turn off appliances and other sources of combustion - furnace, water heater,

range (wood, coal or kerosene burning) stove, heater or fireplace, RV, genera-

tor, automobile.

• Call a qualified technician and have the problem fixed before restarting appli-

ances, the vehicle, and other sources of combustion.

• Immediately get fresh air into premises, RV or vehicle.

EFFECTS ON HUMANS

CO is absorbed by the lungs and reacts with blood hemoglobin to form

carboxyhemoglobin (COHb), which reduces the oxygen carrying capacity

of the blood. If the concentration of CO in air exceeds 2,000 ppm, which

corresponds to 0.2%, it can be fatal in a matter of minutes. In smaller

quantities carbon monoxide will cause a series of symptoms such as

fatigue, headache, nausea, dizziness, collapse and eventually death. The

progression and intensity of these symptoms depends on the time of

exposure and the concentration of CO present in the environment.

WARNING

LITERATURE NUMBER

SACO-2 Carbon Monoxide Detector

Many cases of reported CO poisoning indicate that while victims are aware

they are not feeling 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.

U.S. Department of Labor, Occupational Safety & Health Administration (OSHA)

Regulation 1917.24: "The CO content in any enclosed space shall be maintained at

not more than 50 PPM (0.005%). Remove employees from enclosed space if the

CO concentration exceeds 100 PPM (0.01%)."

The table above refers to healthy adults. Anyone with a health condition

may find lower levels of CO more dangerous than shown in this chart.

COMMON SOURCES OF CO

Common sources of potential dangerous levels of CO are:

• Poorly maintained furnaces, gas heaters or fireplaces.

• Dirty or plugged chimneys or flue exhausts.

• Poorly maintained gas, oil or kerosene appliances.

• Internal combustion engines (e.g., automobiles, lawn mowers and

blowers).
