• Don't waste time collecting possessions after a fire starts.

• Arouse all occupants and leave the building. Your most valuable

possession is your life.

• Doors can mean escape or death. Never open doors without first

checking for heat. Test them with your hands, if they feel warm, fire

may be walled up behind them - leave closed and find another escape

route.

• Call the fire department from OUTSIDE the building.

• If trapped inside, stay close to the floor, cover mouth with cloth,

conserve breath as you crawl to safety.

• Keep all doors and windows closed except for escape purposes.

• NEVER re-enter a burning building.

• Keep your family in a pre-arranged meeting place after your escape.

. PREPARE YOUR OWN ESCAPE PLAN

Most important, when fire strikes, a prepared and practiced escape plan can

make the difference between life and death. Develop an escape plan and

practice it with the entire family, including small children.

• Ensure all family members are familiarized with the alarm signal.

• Draw a Floor Plan of Your Home and determine two exits from each

room. There should be a way to get out of each bedroom without

opening the door.

5 seconds, with the

Red LED light on constantly.

Although many products of combustion can cause discomfort and

adverse health effects, it is carbon monoxide (CO) that presents the

greatest threat to life.

CO is produced by the incomplete combustion of fuels such as natural

gas, propane, heating oil, kerosene, coal, charcoal, gasoline or wood. The

incomplete combustion of fuel can occur in any device that depends on

burning for energy or heat such as furnaces, boilers, room heaters, hot

water heaters, stoves or grills and in any gasoline- powered vehicle or

engine (e.g., generator set or lawnmower). Tobacco smoke also adds CO

to the air you breathe.

When properly installed and maintained, your natural gas furnace and

hot water heater do not pollute your air space with carbon monoxide.

Natural gas is known as a "clean burning" fuel because under correct

operating conditions the combustion products are water vapor and

carbon dioxide, which are not toxic. (Carbon dioxide (CO2) is also

present in the air we exhale and is necessary for plant life.) The products

of combustion are vented from furnaces and water heaters to the outside

by means of a flue duct or chimney.

CAUTION:

Correct operation of fuel-burning equipment requires two key

conditions. There must be:

• An adequate supply of air for complete combustion

• Proper venting of the products of combustion from the furnace

through the chimney, vent or duct to the outside.

Typical Carbon Monoxide Problems.

1. Equipment problems, due to defects, poor maintenance, damage

cracked heat exchangers.

2. Collapsed or blocked chimneys or flues, dislodged, disconnected or

damaged vents.

3. Downdraft in chimneys or flues; this can also be caused by very long or

circuitous flue runs, improper location of flue exhaust or wind

conditions.

4. Improper installation or operation of equipment, chimneys or vents.

5. Air tightness of house envelope results in a lack of air for the

combustion process.

6. Inadequate exhaust of space heaters or appliances.

7. Exhaust ventilation/fireplace competing for air supply.

L. What are the possible symptoms of carbon

monoxide poisoning?

Carbon monoxide (CO) is odorless, colorless, tasteless and very toxic.

When inhaled, it produces an effect known as chemical asphyxiation.

Injury is due to the combining of CO with the available hemoglobin in

the blood, which lowers the oxygen-carrying capacity of the blood. In the

presence of carbon monoxide, the body is quickly affected by oxygen

starvation.

The following symptoms are related to carbon monoxide poisoning and

should be discussed with all members of the household so that you know

what to look for:

Extreme Exposure

: Unconsciousness, convulsions, cardio-

respiratory failure, death

Medium Exposure: Severe throbbing headache, drowsiness,

confusion, vomiting, fast heart rate

Mild Exposure: Slight headache, nausea, fatigue (often described as

mptoms)

"flu-like" sy

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 may

be the first affected. Exposure during sleep is particularly dangerous

because the victim usually does not awaken.

The amount of carbon monoxide in the air is measured as ppm (parts per

million). The graph below shows the important relationship between

carbon monoxide in the air, exposure time and health effects.

For most people, mild symptoms generally will be felt after several hours
