Louisville Home Inspector talks about GFCI Receptacles

Ground Fault Circuit Interrupters (GFCI) are circuit breakers installed at the panel to provide ground faulty protection for the whole circuit. Circuits with GFCI’s need to have fuses or breakers to shut off the electricity in the case of an overload. GFCI’s receptacles are currently required in the United States for bathrooms and washrooms, outdoors, in garages, above counters for a kitchen sink or wet bar, and in unfinished basements and crawlspaces. They are typically installed to protect against electrocution in areas where a person is susceptible to grounding hazards, such as wet locations and when using equipment outside.

There are three types of GFCI’S that can be used in residential properties:

1. The receptacle type is used in place of the standard duplex receptacles found throughout the house. Some GFCI’S may protect other outlets down line in the same circuit. Sometimes the protected outlets will be in different rooms. For example, if an outlet in a patio does not work you should check other locations such as baths or the garage for a tripped GFCI which protects the entire circuit.
2. The circuit breaker type is installed in the electric panel and protects seledted circuits. Although there are limits to the number of outlets protected sometimes a single wire will run from the breaker, through the house, to bathrooms, kitchens and ouside locations protecting each of these.
3. The portable plug in type may be used in area where permanent protection is not available such as with extension cords for power tools operated outside from an unprotected circuit.

Carbon Monoxide Poisoning

A growing number of states and cities are requiring homes to install a device that detects the presence of carbon monoxide, a dangerous gas that kills 2,000 people a year and sickens many times that number.

Surprising to most homeowners, carbon monoxide is the leading cause of accidental poisoning in the U.S. Detectors have been available for almost a decade, to alert people to the gases — odorless and colorless — spewed out by faulty furnaces, stoves and even barbecue grills. However, fewer than one-third of American homes have these inexpensive devices, according to industry surveys.

Just as laws requiring smoke alarms spurred nearly every household to install them during the past 20 years or so, legislators and doctors are hopeful that the new carbon-monoxide detector requirements will have the same effect.

Starting next month, most homes sold in New York state — new or resale — must have a carbon-monoxide monitor. Similar laws have already passed in Rhode Island, New Jersey and West Virginia. A number of other states are contemplating legislation. Action is being taken at the local level too: Cities such as Chicago and St. Louis have ordinances requiring detectors.

“A detector can save families from something they can not control,” says Stephen Gladstone, vice president of the American Society of Home Inspectors. “If somebody doesn’t have a carbon-monoxide alarm and their heating system malfunctions, they might just not wake up.” Nearly a decade ago, tennis star Vitas Gerulaitis died of carbon-monoxide poisoning from a faulty heater.

Legislation seems to have life-saving effects: Cities with ordinances that require carbon-monoxide detectors have much lower death rates from exposure to the gas than those that don’t, according to a study published last year in the American Journal of Emergency Medicine.

While fires and automobiles are the top producers of carbon monoxide, a typical family home has many possible culprits. Furnaces, kitchen stoves, water heaters, fireplaces, generators, camping stoves and charcoal barbecues — anything that burns fossil fuels such as gasoline, diesel fuel, wood and kerosene — can produce dangerous levels of the gas.

Carbon monoxide is produced when these fossil fuels don’t burn completely. Incomplete or “dirty” burning can occur if rust or grime falls into a furnace burner, if equipment cracks or rusts, if gas pressure is out of adjustment or if there isn’t proper ventilation for these devices. Health officials have seen carbon-monoxide poisoning occur after people warm up their cars in their garages, even for a few minutes.

“It can be produced so easily and it can spill into a home so easily,” says Tom Greiner, an Iowa human-housing engineer who is pressing for a law in his state to require detectors.

Today’s carbon-monoxide detectors don’t go off anytime they sense the gas. Earlier versions of the device (those made before 1998) did that and were tripped off so easily — a car pulling into the garage could cause it to go off — that many consumers saw them as an annoyance and were inclined to ignore them. New models go off when they sense a certain level of gas over a period of time. The detectors measure how many molecules of carbon monoxide are present in one million molecules of air (parts per million). Government regulations state that 50 parts per million is the maximum concentration a healthy adult should sustain over an eight-hour period. (A concentration of 400 parts per million can be life-threatening within three hours.)

Consumers can choose from inexpensive no-frills monitors that simply beep and cost around $15 to fancier $50 devices that have digital displays and flash the concentration detected. There are also combination smoke and carbon-monoxide alarms. Safety experts recommend that an alarm be placed outside bedrooms and on each floor of the house. Some also suggest putting a detector near carbon-monoxide-producing devices such as furnaces. Manufacturers suggest that people replace their alarms every seven years since sensors can degrade and electronics can fail. Companies that sell detectors include U.K.-based Kidde PLC and BRK Electronics’ First Alert.

Symptoms of carbon-monoxide poisoning vary depending on the concentration of gas in the air. Mild carbon-monoxide exposure often mimics the flu or food poisoning — with headaches, nausea, vomiting and fatigue — and is thus commonly misdiagnosed. Higher concentrations of carbon monoxide can cause almost immediate dizziness and nausea and can lead to convulsions, coma and death within a few hours, or even minutes at extremely high concentrations. Small children and those with heart and respiratory conditions are most at risk. And some patients complain of neurological symptoms months and even years after exposure.

Carbon monoxide suffocates the cells of the body: It enters the bloodstream and prevents the release of oxygen to the tissue. The only treatment for carbon-monoxide poisoning is to immediately leave the source of the gas and to administer oxygen.

If you suspect carbon monoxide poisoning in your Kentuckiana home, get everyone out of the building immediately, and call 911.  If it is safe to do so open windows to allow entry of fresh air, and turn off any appliances your suspect my be releasing the carbon monoxide.

When needing to test for carbon monoxie in your home locate a home inspector in Southern Indiana or Louisville Kentucky. Be sure to call one that is certified, licensed and insured. Certainty Home Inspections has three licensed home inspectors to make sure we can get your inspection done in the time you have left on your real estate contract. Don’t waste your money on a cheap Charlie inspector, have “Certainty” with your new home purchase.
