Every year thousands of people die from fires in the home. Fire kills an estimated 4,000 Americans every year. Another 30,000 people are seriously injured by fire each year. Property damage from fire costs us at least $11.2 billion yearly. Most fire victims feel that fire would "never happen to them."

Although we like to feel safe at home, about two-thirds of our nation's fire deaths happen in the victim's own home. The home is where we are at the greatest risk and where we must take the most precautions. Most deaths occur from inhaling smoke or poisonous gases, not from the flames.

Most fatal fires occur in residential buildings between 11 p.m. and 6 a.m. when occupants are more likely to be asleep. More than 90 percent of fire deaths in buildings occur in residential dwellings.

A Johns Hopkins University study, funded by the United States Fire Administration, found that 75 percent of residential fire deaths and 84 percent of residential fire injuries could have been prevented by smoke detectors.

There are two basic type of smoke detectors:

1. Ionization detectors - Ionization detectors contain radioactive material that ionizes the air, making an electrical path. When smoke enters, the smoke molecules attach themselves to the ions. The change in electric current flow triggers the alarm. The radioactive material is called americium. It's a radioactive metallic element produced by bombardment of plutonium with high energy neutrons. The amount is very small and not harmful.

    

2. Photo-electric detectors - These type of detectors contain a light source (usually a bulb) and a photocell, which is activated by light. Light from the bulb reflects off the smoke particles and is directed towards the photocell. The photocell then is activated to trigger the alarm.

Choosing a smoke detector
When choosing a smoke detector, there are several things to consider. Think about which areas of the house you want to protect, where fire would be most dangerous, how many you will need, etc.

The Peachtree City Fire Department recomends that every home have a smoke detector outside each sleeping area (inside as well if members of the household sleep with the door closed) and on every level of the home, including the basement. The National Fire Alarm code requires a smoke detector inside each sleeping area for new construction. On floors without bedrooms, detectors should be installed in or near living areas, such as dens, living rooms or family rooms. Smoke detectors are not recommended for kitchens.

The safest bet is to have both kinds or a combination detector with a battery back up. Be sure to check for a testing laboratory label on the detector. It means that samples of that particular model have been tested under operating conditions. Check to see if it is easy to maintain and clean. Be sure bulbs and batteries are easy to purchase and convenient to install.

Installation
The placement of smoke detectors is very important. Sleeping areas need the most protection. One detector in a short hallway outside the bedroom area is usually adequate. Hallways longer than 30 feet should have one at each end. For maximum protection, install a detector in each bedroom.

Be sure to keep the detector away from fireplaces and wood stoves to avoid false alarms. Place smoke detectors at the top of each stairwell and at the end of each long hallway. Smoke rises easily through stairwells. If you should put a smoke detector in your kitchen, be sure to keep it away from cooking fumes or smoking areas.

Proper mounting of a smoke detector also is important. You can mount many detectors by yourself, but those connected to your household wiring should have their own separate circuit and be installed by a professional electrician. If you mount your detector on the ceiling, be sure to keep it at least 18 inches away from dead air space near walls and corners. If you mount it on the wall, place it six to 12 inches below the ceiling and away from corners. Keep them high because smoke rises.

Never place them any closer than three feet from an air register that might recirculate smoke. Don't place them near doorways or windows where drafts could impair the detector operation. Don't place them on an uninsulated exterior wall or ceiling. Temperature extremes can affect the batteries.

Maintenance
Keeping smoke detectors in good condition is easy. Always follow the manufacturer's instructions. Be sure to replace the batteries every year or as needed. Most models will make a chirping, popping or beeping sound when the battery is losing its charge. When this sound is heard, install a fresh battery, preferably an alkaline type.

Replace bulbs every three years or as needed. Keep extras handy. Check the smoke detector every 30 days by releasing smoke or pushing the test button. Clean the detector face and grillwork often to remove dust and grease. Never paint a smoke detector as it will hamper its function. Check your detector if you've been away from home.

If you're looking for a novel gift for somebody, consider giving them a smoke detector. It's an interesting gift that can save lives and it shows that you care.



Carbon Monoxide Detectors

According to the Journal of the American Medical Association, carbon monoxide poisoning is the leading cause of accidental poisoning deaths in America. Carbon monoxide detectors are available, but you need to understand how they work and what their limitations are in order to decide whether or not you need a detector and, if you purchase a detector, how to use it to get the best protection.

What is Carbon Monoxide?

Carbon monoxide is an odorless, tasteless, invisible gas. Each carbon monoxide molecule is composed of a single carbon atom bonded to a single oxygen atom. Carbon monoxide results from the incomplete combustion of fossil fuels, such as wood, kerosene, gasoline, charcoal, propane, natural gas, and oil.

Where is Carbon Monoxide Found?

Carbon monoxide is present in low levels in the air. In the home, it is formed from incomplete combustion from any flame-fueled (i.e., not electric) device, including ranges, ovens, clothes dryers, furnaces, fireplaces, grills, space heaters, vehicles, and water heaters. Furnaces and water heaters may be sources of carbon monoxide, but if they are vented properly the carbon monoxide will escape to the outside. Open flames, such as from ovens and ranges, are the most common source of carbon monoxide. Vehicles are the most common cause of carbon monoxide poisoning.

How Do Carbon Monoxide Detectors Work?

Carbon monoxide detectors trigger an alarm based on an accumulation of carbon monoxide over time. Carbon monoxide can harm you if you are exposed to high levels of carbon monoxide in a short period of time, or to lower levels of carbon monoxide over a long period of time. Carbon monoxide detectors require a continuous power supply, so if the power cuts off then the alarm becomes ineffective. Models are available that offer back-up battery power.

Why is Carbon Monoxide Dangerous?

When carbon monoxide is inhaled, it passes from the lungs into the hemoglobin molecules of red blood cells. Carbon monoxide binds to hemoglobin at the same site as and preferentially to oxygen, forming carboxyhemoglobin. Carboxyhemoglobin interferes with the oxygen transport and gas exchange abilities of red blood cells. The result is that the body becomes oxygen-starved, which can result in tissue damage and death. Low levels of carbon monoxide poisoning cause symptoms similar to those of the flu or a cold, including shortness of breath on mild exertion, mild headaches, and nausea. Higher levels of poisoning lead to dizziness, mental confusion, severe headaches, nausea, and fainting on mild exertion. Ultimately, carbon monoxide poisoning can result in unconsciousness, permanent brain damage, and death. Carbon monoxide detectors are set to sound an alarm before the exposure to carbon monoxide would present a hazard to a healthy adult. Babies, children, pregnant women, people with circulatory or respiratory ailments, and the elderly are more sensitive to carbon monoxide than healthy adults.

Where Should I Place a Carbon Monoxide Detector?

Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance. Keep the detector out of the way of pets and children. Each floor needs a separate detector. If you getting a single carbon monoxide detector, place it near the sleeping area and make certain the alarm is loud enough to wake you up.

What Do I Do if the Alarm Sounds?

First, read your detector's operation manual and know what type of sound the detector will make in an actual alarm. CO detectors, much like smoke detectors, often have a low-battery 'alert' feature that produces an intermittent chirp every few minutes to alert you that the battery requires changing. Typically, if the detector is activated due to the presence of CO the detector will sound an alarm continually. Don't ignore the alarm! It is intended to go off before you are experiencing symptoms. Get all members of the household to fresh air, and ask whether anyone is experiencing any of the symptoms of carbon monoxide poisoning. If anyone is experiencing symptoms of carbon monoxide poisoning, call 911. If no one has symptoms, ventilate the building, identify and remedy the source of the carbon monoxide before returning inside, and have appliances or chimneys checked by a professional as soon as possible.

Additional Carbon Monoxide Concerns and Information

Don't automatically assume that you need or don't need a carbon monoxide detector. Also, don't assume that you are safe from carbon monoxide poisoning just because you have a detector installed. Carbon monoxide detectors are intended to protect healthy adults, so take the ages and health of family members into account when assessing the effectiveness of a detector. Also, be aware that the average life span of many carbon monoxide detectors is about 2 years. The 'test' feature on many detectors checks the functioning of the alarm and not the status of the detector. There are detectors that last longer, indicate when they need to be replaced, and have power supply backups -- you need to check to see whether a particular model has the features you require. When deciding whether or not to purchase a carbon monoxide detector, you need to consider not only the number and type of carbon monoxide sources, but also the construction of the building. Newer building may have more airtight construction and may be better insulated, which make it easier for carbon monoxide to accumulate.
