CHILDPROOFING YOUR HOME

 12 Safety Devices

About 2.5 million children are injured or killed by hazards in the home each year. The good news is that many of these incidents can be prevented by using simple child-safety devices on the market today. Any safety device you buy should be sturdy enough to prevent injury to your child, yet easy for you to use. It's important to follow installation instructions carefully. In addition, if you have older children in the house, be sure they re-secure safety devices. Remember, too, that no device is completely childproof; determined youngsters have been known to disable them. You can childproof your home for a fraction of what it would cost to have a professional do it. And safety devices are easy to find. You can buy them at hardware stores, baby equipment shops, supermarkets, drug stores, home and linen stores, and through online and mail-order catalogues.
InterNACHI inspectors, too, should know what to tell clients who are concerned about the safety of their children. Here are some child-safety devices that can help prevent many injuries to young children. 
1.  Use safety latches and locks for cabinets and drawers in kitchens, bathrooms, and other areas to help prevent poisonings and other injuries. Safety latches and locks on cabinets and drawers can help prevent children from gaining access to medicines and household cleaners, as well as knives and other sharp objects.
Look for safety latches and locks that adults can easily install and use, but that are sturdy enough to withstand pulls and tugs from children. Safety latches are not a guarantee of protection, but they can make it more difficult for children to reach dangerous substances. Even products with child-resistant packaging should be locked away out of reach; this packaging is not childproof.
Typical cost of a safety latch or lock: less than $2.
2.  Use safety gates to help prevent falls down stairs and to keep children away from dangerous areas. Look for safety gates that children cannot dislodge easily, but that adults can open and close without difficulty. For the top of stairs, gates that screw into the wall are more secure than "pressure gates." 
New safety gates that meet safety standards display a certification seal from the Juvenile Products Manufacturers Association (JPMA). If you have an older safety gate, be sure it doesn't have "V" shapes that are large enough for a child's head and neck to fit into.
Typical cost of a safety gate: $13 to $40.
3.  Use door knob covers and door locks to help prevent children from entering rooms and other areas with possible dangers, including swimming pools.
Be sure the door knob cover is sturdy enough not to break, but allows a door to be opened quickly by an adult in case of emergency. By restricting access to potentially hazardous rooms in the home, door knob covers could help prevent many kinds of injuries. To prevent access to swimming pools, door locks should be placed high, out of reach of young children. Locks should be used in addition to fences and door alarms. Sliding glass doors, with locks that must be re-secured after each use, are often not an effective barrier to pools.
Typical cost of a door knob cover: $1; door lock: $5 and up.
4.  Use anti-scald devices for faucets and shower heads, and set your water heater temperature to 120° F to help prevent burns from hot water. A plumber may need to install these. 
Typical cost of an anti-scald device: $6 to $30.
5.  Use smoke detectors on every level of your home and near bedrooms to alert you to fires. Smoke detectors are essential safety devices for protection against fire deaths and injuries. Check smoke detectors once a month to make sure they're working. If detectors are battery-operated, change batteries at least once a year, or consider using 10-year batteries.
Typical cost of a smoke detector: less than $10.
6.  Use window guards and safety netting to help prevent falls from windows, balconies, decks and landings. Window guards and safety netting for balconies and decks can help prevent serious falls.  Check these safety devices frequently to make sure they are secure and properly installed and maintained. There should be no more than 4 inches between the bars of the window guard. If you have window guards, be sure at least one window in each room can be easily used for escape in a fire. Window screens are not effective for preventing children from falling out of windows.
Typical cost of a window guard or safety netting: $8 to $16.
7.  Use corner and edge bumpers to help prevent injuries from falls against sharp edges of furniture and fireplaces. Corner and edge bumpers can be used with furniture and fireplace hearths to help prevent injuries from falls, and to soften falls against sharp and rough edges.
Be sure to look for bumpers that stay securely on furniture and hearth edges.
Typical cost of a corner and edge bumper: $1 and up.
8.  Use outlet covers and outlet plates to help prevent children from electrical shock and possible electrocution.
Be sure the outlet protectors cannot be easily removed by children and are large enough so that children cannot choke on them.
Typical cost of an outlet cover: less than $2.
9.  Use a carbon monoxide (CO) detector outside bedrooms to help prevent CO poisoning. Consumers should install CO detectors near sleeping areas in their homes. Households that should use CO detectors include those with gas or oil heat or with attached garages.
Typical cost of a carbon monoxide (CO) detector: $30 to $70.
10.  Cut window blind cords; use safety tassels and inner cord stops instead to help prevent children from strangling in blind-cord loops. Window blind cord safety tassels on miniblinds and tension devices on vertical blinds and drapery cords can help prevent deaths and injuries from strangulation in the loops of cords. Inner cord stops can help prevent strangulation in the inner cords of window blinds.
For older miniblinds, cut the cord loop, remove the buckle, and put safety tassels on each cord. Be sure that older vertical blinds and drapery cords have tension or tie-down devices to hold the cords tight. When buying new miniblinds, vertical blinds and draperies, ask for safety features to prevent child strangulation.

Prices vary.

11.  Use door stops and door Hholders to help prevent injuries to fingers and hands. Door stops and door holders on doors and door hinges can help prevent small fingers and hands from being pinched or crushed in doors and door hinges.
Be sure any safety device for doors is easy to use and is not likely to break into small parts, which could be a choking hazard for young children.
Typical cost of a door stop and door holder: less than $4.
12.  Use a cell or cordless phone to make it easier to continuously watch young children, especially when they're in bathtubs, swimming pools, or other potentially dangerous areas. Cordless phones help you watch your child continuously without leaving the vicinity to answer a phone call. Cordless phones are especially helpful when children are in or near water, whether it's the bathtub, the swimming pool, or the beach.
Typical cost of a cordless phone: $30 and up.
In summary, there are a number of different safety devices that can be purchased to ensure the safety of children in the home. Homeowners can ask an InterNACHI inspector about these and other safety measures during their next inspection.

10 EASY WAYS TO SAVE ENERGY

Most people don’t know how easy it is to make their homes run on less energy, and here at InterNACHI, we want to change that. Drastic reductions in heating, cooling and electricity costs can be accomplished through very simple changes, most of which homeowners can do themselves. Of course, for homeowners who want their homes to take advantage of the most up-to-date knowledge and systems in home energy-efficiency, InterNACHI energy auditors can perform in-depth testing to find the best energy solutions for your particular home. 
Why make your home more energy efficient? Here are a few good reasons:
  • Federal, state, utility and local jurisdictions' financial incentives, such as tax breaks, are very advantageous in most parts of the U.S.
  • It saves money. It costs less to power a home that has been converted to be more energy-efficient.
  • It increases indoor comfort levels.
  • It reduces our impact on climate change. Many scientists now believe that excessive energy consumption contributes significantly to global warming.
  • It reduces pollution. Conventional power production introduces pollutants that find their way into the air, soil and water supplies.
1. Find better ways to heat and cool your house. 
As much as half of the energy used in homes goes toward heating and cooling. The following are a few ways that energy bills can be reduced through adjustments to the heating and cooling systems:
  • Install a ceiling fan. Ceiling fans can be used in place of air conditioners, which require a large amount of energy.
  • Periodically replace air filters in air conditioners and heaters.
  • Set thermostats to an appropriate temperature. Specifically, they should be turned down at night and when no one is home. In most homes, about 2% of the heating bill will be saved for each degree that the thermostat is lowered for at least eight hours each day. Turning down the thermostat from 75° F to 70°F, for example, saves about 10% on heating costs.
  • Install a programmable thermostat. A programmable thermostat saves money by allowing heating and cooling appliances to be automatically turned down during times that no one is home and at night. Programmable thermostats contain no mercury and, in some climate zones, can save up to $150 per year in energy costs.
  • Install a wood stove or a pellet stove. These are more efficient sources of heat than furnaces.
  • At night, curtains drawn over windows will better insulate the room.
2. Install a tankless water heater.
Demand water heaters (tankless or instantaneous) provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which will save on energy costs. Demand water heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses required by traditional storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, demand water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water.
3. Replace incandescent lights.
The average household dedicates 11% of its energy budget to lighting. Traditional incandescent lights convert approximately only 10% of the energy they consume into light, while the rest becomes heat. The use of new lighting technologies, such as light-emitting diodes (LEDs) and compact fluorescent lamps (CFL), can reduce energy use required by lighting by 50% to 75%. Advances in lighting controls offer further energy savings by reducing the amount of time lights are on but not being used. Here are some facts about CFLs and LEDs:
  • CFLs use 75% less energy and last about 10 times longer than traditional incandescent bulbs.
  • LEDs last even longer than CFLs and consume less energy.
  • LEDs have no moving parts and, unlike CFLs, they contain no mercury.
4. Seal and insulate your home.
Sealing and insulating your home is one of the most cost-effective ways to make a home more comfortable and energy efficient -– and you can do it yourself. A tightly sealed home can improve comfort and indoor air quality while reducing utility bills. An InterNACHI energy auditor can be hired to assess envelope leakage and recommend fixes that will dramatically increase comfort and energy savings.
The following are some common places where leakage may occur:
  • electrical outlets;
  • mail slots;
  • around pipes and wires;
  • wall- or window-mounted air conditioners;
  • attic hatches;
  • fireplace dampers;
  • weatherstripping around doors;
  • baseboards;
  • window frames; and
  • switch plates.
Because hot air rises, air leaks are most likely to occur in the attic. Homeowners can perform a variety of repairs and maintenance to their attics that save them money on cooling and heating, such as: 
  • Plug the large holes. Locations in the attic where leakage is most likely to be the greatest are where walls meet the attic floor, behind and under attic knee walls, and in dropped-ceiling areas.
  • Seal the small holes. You can easily do this by looking for areas where the insulation is darkened. Darkened insulation is a result of dusty interior air being filtered by insulation before leaking through small holes in the building envelope. In cold weather, you may see frosty areas in the insulation caused by warm, moist air condensing and then freezing as it hits the cold attic air. In warmer weather, you’ll find water staining in these same areas. Use expanding foam or caulk to seal the openings around plumbing vent pipes and electrical wires. Cover the areas with insulation after the caulk is dry.
  • Seal up the attic access panel with weatherstripping. You can cut a piece of fiberglass or rigid foam board insulation the same size as the attic hatch and glue it to the back of the attic access panel. If you have pull-down attic stairs or an attic door, these should be sealed in a similar manner.
5. Install efficient shower heads and toilets.
The following systems can be installed to conserve water usage in homes:
  • low-flow shower heads. They are available in different flow rates, and some have a pause button which shuts off the water while the bather lathers up;
  • low-flow toilets. Toilets consume 30% to 40% of the total water used in homes, making them the biggest water users. Replacing an older 3.5-gallon toilet with a modern, low-flow 1.6-gallon toilet can reduce usage an average of two gallons-per-flush (GPF), saving 12,000 gallons of water per year. Low-flow toilets usually have "1.6 GPF" marked on the bowl behind the seat or inside the tank;
  • vacuum-assist toilets. These types of toilets have a vacuum chamber which uses a siphon action to suck air from the trap beneath the bowl, allowing it to quickly fill with water to clear waste. Vacuum toilets are relatively quiet; and
  • dual-flush toilets. Dual-flush toilets have been used in Europe and Australia for years, and are now gaining in popularity in the U.S. Dual-flush toilets let you choose between a 1-gallon (or less) flush for liquid waste, and a 1.6-gallon flush for solid waste. Dual-flush 1.6-GPF toilets reduce water consumption by an additional 30%.
6. Use appliances and electronics responsibly.
Appliances and electronics account for about 20% of household energy bills in a typical U.S. home. The following are tips that will reduce the required energy of electronics and appliances:
  • Refrigerators and freezers should not be located near the stove, dishwasher or heat vents, or exposed to direct sunlight. Exposure to warm areas will force them to use more energy to remain cool.  
  • Computers should be shut off when not in use. If unattended computers must be left on, their monitors should be shut off. According to some studies, computers account for approximately 3% of all energy consumption in the United States.
  • Use efficient “Energy Star”-rated appliances and electronics. These devices, approved by the DOE and the EPA’s Energy Star Program, include TVs, home theater systems, DVD players, CD players, receivers, speakers and more. According to the EPA, if just 10% of homes used energy-efficient appliances, it would reduce carbon emissions by the equivalent of 1.7 million acres of trees.
  • Chargers, such as those for laptops and cell phones, consume energy when they are plugged in. When they are not connected to electronics, chargers should be unplugged.
  • Laptop computers consume considerably less electricity than desktop computers.
7. Install daylighting as an alternative to electrical lighting.
Daylighting is the practice of using natural light to illuminate the home's interior. It can be achieved using the following approaches:
  • skylights. It’s important that they be double-pane or they may not be cost-effective. Flashing skylights correctly is key to avoiding leaks;
  • lightshelves. Light shelves are passive devices designed to bounce light deep into a building. They may be interior or exterior. Light shelves can introduce light into a space up to 2½ times the distance from the floor to the top of the window, and advanced light shelves may introduce four times that amount;
  • clerestory windows.  Clerestory windows are short, wide windows set high on the wall. Protected from the summer sun by the roof overhang, they allow winter sun to shine through for natural lighting and warmth; and 
  • light tubes.  Light tubes use a special lens designed to amplify low-level light and reduce light intensity from the midday sun. Sunlight is channeled through a tube coated with a highly reflective material, then enters the living space through a diffuser designed to distribute light evenly.
8. Insulate windows and doors.
About one-third of the home's total heat loss usually occurs through windows and doors. The following are ways to reduce energy lost through windows and doors:
  • Seal all window edges and cracks with rope caulk. This is the cheapest and simplest option.
  • Windows can be weatherstripped with a special lining that is inserted between the window and the frame. For doors, weatherstrip around the whole perimeter to ensure a tight seal when closed. Install quality door sweeps on the bottom of the doors, if they aren't already in place.
  • Install storm windows at windows with only single panes. A removable glass frame can be installed over an existing window.
  • If existing windows have rotted or damaged wood, cracked glass, missing putty, poorly fitting sashes, or locks that don't work, they should be repaired or replaced.
9. Cook smart.
An enormous amount of energy is wasted while cooking. The following recommendations and statistics illustrate less wasteful ways of cooking:
  • Convection ovens are more efficient that conventional ovens. They use fans to force hot air to circulate more evenly, thereby allowing food to be cooked at a lower temperature. Convection ovens use approximately 20% less electricity than conventional ovens.
  • Microwave ovens consume approximately 80% less energy than conventional ovens.
  • Pans should be placed on the correctly-sized heating element or flame. 
  • Lids make food heat more quickly than pans that do not have lids.
  • Pressure cookers reduce cooking time dramatically.
  • When using conventional ovens, food should be placed on the top rack. The top rack is hotter and will cook food faster. 
10. Change the way you wash your clothes.
  • Do not use the “half load” setting on your washer. Wait until you have a full load of clothes, as the “half load” setting saves less than half of the water and energy.
  • Avoid using high-temperature settings when clothes are not that dirty. Water that is 140 degrees uses far more energy than 103 degrees for a "warm" setting, but 140 degrees isn’t that much better for washing purposes.
  • Clean the lint trap before you use the dryer, every time. Not only is excess lint a fire hazard, but it will prolong the amount of time required for your clothes to dry.
  • If possible, air-dry your clothes on lines and racks.
  • Spin-dry or wring clothes out before putting them into a dryer. 
Homeowners who take the initiative to make these changes usually discover that the energy savings are more than worth the effort. However, you should consider that inspectors can make this process much easier and perform a more comprehensive assessment of energy saving potential than you can.

Priority Maintenance

There are so many home maintenance and repair items that are important; it can be confusing trying to establish which are the most critical. To simplify things, we have compiled a short list of our favorites. These are by no means all-inclusive, nor do they replace any of the information in a home inspection report. They should, however, help you get started on the right foot. Remember, any items marked as priority or safety issues on your home inspection report need immediate attention.

One-Time Tasks
1. Install smoke detectors as necessary (usually one on each level of the home, near any sleeping areas). Install carbon monoxide detectors, according to manufacturer’s recommendations.
2. Make any electrical improvements recommended in the home inspection report.
3. Remove any wood/soil contact to prevent rot and insect damage.
4. Change the locks on all doors. Use a dead bolt for better security and to minimize insurance costs.
5. Correct trip hazards such as broken or uneven walks and driveways, loose or torn carpet or uneven flooring.
6. Correct unsafe stairways and landings. (Railings missing, loose, too low, et cetera.)
7. Have all chimneys inspected before operating any of these appliances.
8. Locate and mark the shut-offs for the heating, electrical and plumbing systems.
9. Label the circuits in electrical panels.
10. If there is a septic system, have the tank pumped and inspected. If the house is on a private water supply (well), set up a regular testing procedure for checking water quality.


Regular Maintenance Items
11. Clean the gutters in the spring and fall.
12. Check for damaged roofing and flashing materials twice a year.
13. Cut back trees and shrubs from the house walls, roof and air conditioning system as needed.
14. Clean the tracks on horizontal sliding windows annually, and ensure the drain holes are clear.
15. Test ground fault circuit interrupters, carbon monoxide detectors and smoke detectors using the test button, monthly.
16. Service furnace or boiler yearly.
17. Check furnace filters, humidifiers and electronic air cleaners monthly.
18. Check the bathtub and shower caulking monthly and improve promptly as needed.
19. If you are in a climate where freezing occurs, shut off outdoor water faucets in the fall.
20. Check reversing mechanism on garage door opener monthly.
21. Check attics for evidence of leaks and condensation and make sure vents are not obstructed, at least twice a year. (Provide access into all attics and crawl spaces.)

AIR QUALITY IN THE HOME

Indoor air quality is generally worse than most people believe,
but there are things you can do about it.
 
Some Quick Facts:
  • Indoor air quality can be worse than that of outdoor air.
  • Problems can arise from moisture, insects, pets, appliances, radon, materials used in household products and furnishings, smoke, and other sources.
  • Effects range from minor annoyances to major health risks.
  • Remedies include ventilation, cleaning, moisture control, inspections, and following manufacturers' directions when using appliances and products.
Research has shown that the quality of indoor air can be worse than that of outdoor air. Many homes are built or remodeled more tightly, without regard to the factors that assure fresh and healthy indoor air. Our homes today contain many furnishings, appliances and products that can affect indoor air quality.
 
Signs of indoor air quality problems include:
  • unusual and noticeable odors;
  • stale or stuffy air;
  • a noticeable lack of air movement;
  • dirty or faulty central heating or air-conditioning equipment;
  • damaged flue pipes and chimneys;
  • unvented combustion air sources for fossil-fuel appliances;
  • excessive humidity;
  • the presence of molds and mildew;
  • adverse health reaction after remodeling, weatherizing, bringing in new furniture, using household and hobby products, and moving into a new home; and
  • feeling noticeably healthier outside.
 
Common Sources of Air Quality Problems
Poor indoor air quality can arise from many sources. At least some of the following contaminants can be found in almost any home:
  • moisture and biological pollutants, such as molds, mildew, dust mites, animal dander, and cockroaches;
  • high humidity levels, inadequate ventilation, and poorly maintained humidifiers and air conditioners;
  • combustion products, including carbon monoxide, from unvented fossil-fuel space heaters, unvented gas stoves and ovens, and back-drafting from furnaces and water heaters;
  • formaldehyde from durable-press draperies and other textiles, particleboard products, such as cabinets and furniture framing, and adhesives;
  • radon, which is a radioactive gas from the soil and rock beneath and around the home's foundation, groundwater wells, and some building materials;
  • household products and furnishings, such as paints, solvents, air fresheners, hobby supplies, dry-cleaned clothing, aerosol sprays, adhesives, and fabric additives used in carpeting and furniture, which can release volatile organic compounds (VOCs);
  • asbestos, which is found in most homes more than 20 years old. Sources include deteriorating, damaged and disturbed pipe insulation, fire retardant, acoustical material (such as ceiling tiles) and floor tiles;
  • lead from lead-based paint dust, which is created when removing paint by sanding, scraping and burning;
  • particulates from dust and pollen, fireplaces, wood stoves, kerosene heaters and unvented gas space heaters; and
  • tobacco smoke, which produces particulates, combustion products and formaldehyde.
 
Remedies to Indoor Air Quality Problems
 
Living Areas
Paneling, pressed-wood furniture, and cabinetry may release formaldehyde gas.
Remedy: Ask about formaldehyde content before buying furniture and cabinets. Some types of pressed-wood products, such as those with phenol resin, emit less formaldehyde. Also, products coated with polyurethane or laminates may reduce formaldehyde emissions. After installation, open windows. Maintain moderate temperature and humidity.
 
Biological pollutants can grow on water-damaged carpet. New carpet can release organic gases.  
Remedy: Promptly clean and dry water-damaged carpet, or remove it altogether. If adhesives are needed, ask for low-emitting ones. During installation, open doors and windows, and use window fans or room air conditioners. Vacuum regularly. Consider area rugs instead of wall-to-wall carpet. Rugs are easier to remove and clean, and the floor underneath can also be cleaned.
 
Some floor tiles contain asbestos.
Remedy: Periodically inspect for damage or deterioration. Do not cut, rip, sand or remove any asbestos-containing materials. If you plan to make changes that might disturb the asbestos, or if materials are more than slightly damaged, contact a professional for repair or removal. Call your local or state health department or the Environmental Protection Agency.
 
Moisture encourages biological pollutants including allergens, such as mold, mildew, dust mites and cockroaches.
Remedy: If possible, eliminate moisture sources. Install and use exhaust fans. Use a dehumidifier, if necessary. Remove molds and mildew by cleaning with a solution of chlorine bleach (1 cup bleach to 1 gallon water). Maintain fresh air with natural and mechanical air circulation.
 
Your fireplace can be a source of carbon monoxide and combustion pollutants.
Remedy: Open the flue when using the fireplace. Have the flue and chimney inspected annually for exhaust back-drafting, flue obstructions, cracks, excess creosote, and other damage. Install smoke and carbon monoxide detectors.
 
An air conditioner can be a source of biological allergens.
Remedy: If there is a water tray, empty and clean it often. Follow all service and maintenance procedures, including changing the filter.
 
Gas and kerosene space heaters can release carbon monoxide and combustion pollutants.
Remedy: Never use unvented kerosene or gas space heaters. In the room where the heater is located, provide fresh air by opening a door to the rest of the house, turning on an exhaust fan, and slightly opening a window.
 
Tobacco smoke contains harmful combustion and particulate pollutants, including carbon monoxide and combustion byproducts.
Remedy: Do not smoke in your home or permit others to do so, especially near children. If smoking cannot be avoided indoors, open windows and use exhaust fans.
 
New draperies may be treated with a formaldehyde-based finish and emit odors for a short time.
Remedy: Before hanging, air draperies to ventilate odors. After hanging, ventilate the area. Maintain moderate temperature and humidity.
 
Paint manufactured before l978 may contain lead.
Remedy: Leave lead-based paint undisturbed if it is in good condition. Before removing paint, test for lead. Do-it-yourself lead test kits are available from hardware and building supply stores. Do not sand, burn off or remove lead-based paint yourself. Hire a person with special training to correct lead-based paint problems. For more information, call 1-800-LEAD-FYI.
 
Many animals create airborne allergens, such as dander, hair, feathers and skin.
Remedy: Keep pets outdoors as much as possible. Clean the entire house regularly. Deep-clean areas where pets are permitted. Bathe pets regularly.
 
Biological allergens caused by dust mites can trigger asthma.
Remedy: Clean and vacuum regularly. Wash bedding in water hotter than 130 degrees F. Use more hard-surface finishes; they are less likely to attract and hold dust mites.
 
Kitchen
Unhealthy and irritating vapors may be released from chemicals in household cleaners and similar products. Remedy: Select nonaerosol and non-toxic products. Use, apply, store and dispose of them according to manufacturers' directions. If products are concentrated, label the storage container with dilution instructions. Use up a product completely before discarding its container.
 
Pressed-wood cabinets can be a source of formaldehyde vapor.
Remedy: Maintain moderate temperatures (80 degrees maximum) and humidity (about 45%). When purchasing new cabinets, select solid wood or metal cabinets, or those made with phenol resin; they emit less formaldehyde. Ventilate well after installation.
 
Unvented gas stoves and ranges are sources of carbon monoxide and combustion byproducts.
Remedy: Keep appliance burners clean. Have burners periodically adjusted (blue-flame tip, not yellow). Install and use an exhaust fan. Never use a gas range or stove to heat your home.
 
Bathroom
Organic gases are released from chemicals in some personal care products, such as deodorant, hair spray, shampoo, toner, nail polish and perfumes.
Remedy: Select odor-free or low odor-producing products. Select nonaerosol varieties. Open a window, or use an exhaust fan. Follow manufacturers' directions when using the product and disposing of containers.
 
Air fresheners can release organic gases.
Remedy: Open a window or use the exhaust fan. Follow manufacturers' directions. Select natural products.
 
Bedroom
Humidifiers and cold-mist vaporizers can encourage biological allergens, including mold, mildew and cockroaches, that can trigger asthma, and encourage the spread of viruses and the growth of bacteria.
Remedy: Use and clean these appliances according to manufacturers' directions. Refill daily with fresh water.
 
Moth repellents often contain the pesticide paradichlorobenzene.
Remedy: Avoid breathing vapors. Place them in tightly sealed trunks or other containers. Store separately, away from living areas.
 
Chemicals used in the dry-cleaning process release organic gases.
Remedy: Bring any odors to the attention of your dry cleaner. Try to air out dry-cleaned goods before bringing them indoors. Seek alternatives to dry cleaning, such as hand washing items.  Consider using green dry cleaners who use newer, non-toxic solvents and methods to clean garments.
 
Utility Room
Unvented gas clothes dryers produce carbon monoxide and combustion byproducts and can be a fire hazard. Remedy: Regularly dispose of lint around and under the dryer. Provide air for gas units. Vent the dryer directly to the outdoors. Clean the lint trap, vent and ductwork regularly.
 
Gas and oil furnaces and boilers, and gas water heaters can produce air-quality problems which include back-drafting of carbon monoxide and combustion pollutants.
Remedy: Have your heating system and water heater, including gas piping and venting, inspected every year.
 
Asbestos pipe wrap and furnace insulation can release asbestos fibers into the air.
Remedy: Periodically check for damage and deterioration. Do not cut, rip, sand or remove any asbestos-containing materials. If you plan to make changes that might disturb the asbestos, or if materials are more than slightly damaged, contact a professional for repair or removal.
 
Basement
Ground moisture encourages biological allergens, including mold and mildew.
Remedy: Inspect for condensation on walls, standing water on the floor, and sewage leaks. To keep the basement dry, prevent outside water from entering indoors by installing roof gutters and downspouts, by not watering close to the foundation, by grading soil away from the home, and by applying waterproofing sealants to the basement's interior walls. To prevent the accumulation of standing water, consider installing a sump pump. If sewage is the source of water intrusion, have drains professionally cleaned. If moisture has no obvious source, install an exhaust fan controlled by humidity levels. Remove mold and mildew. Regularly clean and disinfect the basement floor drain.
 
Radon is an invisible, radioactive gas which poses the risk of lung cancer.
Remedy: Test your home for radon. Do-it-yourself kits are inexpensive and easy to use. Have an experienced radon contractor mitigate your home if your radon level is 4 picocuries per liter (pCi/L) or higher.
 
Chemicals in hobby products, such as solvents, paint, glue and epoxy, release organic gases. Remedy: Follow manufacturers' directions for use, ventilation, application, clean-up, and container storage and disposal. Use outdoors when possible. When using indoors, open a window or use an exhaust fan. Re-seal containers tightly. Clean tools outside or in a well-ventilated area.
 
Garage
Car and small engine exhaust are sources of carbon monoxide and combustion byproducts.
Remedy: Never leave vehicles, lawn mowers, snowmobiles, etc., running in the garage.
 
Paint, solvent and cleaning supplies may release harmful vapors.
Remedy: Provide ventilation when using them. Follow manufacturers' directions. Buy only as much as you need. If the products contain methylene chloride, such as paint strippers, use them outdoors. Re-seal containers well. Keep products in their original, labeled containers. Clean brushes and other materials outside.  Opt for non-toxic green products whenever possible.
 
Pesticides and fertilizers used in the yard and garden may be toxic.
Remedy: Use non-chemical methods whenever possible. Follow manufacturers' directions for mixing, applying and storing.  Wear protective clothing. Mix or dilute these products outdoors. Provide ventilation when using them indoors. Store them outside of the home in their original, labeled containers. After using the product, remove your shoes and clean your hands and clothing to avoid bringing the chemicals into your home.

 
Smoke and Carbon Monoxide Detectors
Install a smoke detector in each bedroom or in the adjacent hallway.
If you have gas or other fossil-fuel appliances in the house, install carbon monoxide detectors in these locations.
Combination smoke and carbon monoxide detectors are available.
Check the batteries frequently, at least annually.
 
Amount of Ventilation
If too little outdoor air enters a home, pollutants can accumulate to levels that can pose health and comfort problems. Unless they are built with a special mechanical means of ventilation, homes that are designed and constructed to minimize the amount of outdoor air that can "leak" into and out of the home may have higher pollutant levels than other homes. However, because some weather conditions can drastically reduce the amount of outdoor air that enters a home, pollutants can build up even in homes that are normally considered "leaky."
 
How Does Outdoor Air Enter a House?
Outdoor air enters and leaves a house by infiltration, natural ventilation and mechanical ventilation. In a process known as infiltration, outdoor air flows into the house through openings, joints and cracks in walls, floors and ceilings, and around windows and doors. In natural ventilation, air moves through opened windows and doors. Air movement associated with infiltration and natural ventilation is caused by air-temperature differences between the indoors and outdoors, and by wind. Finally, there are a number of mechanical ventilation devices, from outdoor-vented fans that intermittently remove air from a single room, such as the bathroom and kitchen, to air-handling systems that use fans and ductwork to continuously remove indoor air and distribute filtered and conditioned outdoor air to strategic points throughout the house. The rate at which outdoor air replaces indoor air is described as the air-exchange rate. When there is little infiltration, natural ventilation or mechanical ventilation, the air-exchange rate is low and pollutant levels can increase.
 
Indoor Air Pollution and Health
Health effects from indoor air pollutants may be experienced soon after exposure or, possibly years later.
 
Immediate Effects
Immediate effects may show up after a single exposure, or it may take repeated exposures. These include irritation of the eyes, nose and throat, headaches, dizziness and fatigue. Such immediate effects are usually short-term and treatable. Sometimes, the treatment is simply eliminating the person's exposure to the source of the pollution, if it can be identified. Symptoms of some diseases, including asthma, hypersensitivity pneumonitis, and humidifier fever, may also show up soon after exposure to some indoor air pollutants.
 
The likelihood of immediate reactions to indoor air pollutants depends on several factors. Age and pre-existing medical conditions are two important influences. In other cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological pollutants after repeated exposures, and it appears that some people can become sensitized to chemical pollutants, as well.
 
Certain immediate effects are similar to those from colds and other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place that symptoms occur. If the symptoms fade or go away when a person is away from home, for example, an effort should be made to identify indoor air sources that may be possible causes. Some effects may be made worse by an inadequate supply of outdoor air, or from the heating, cooling or humidity conditions prevalent in the home.
 
Long-Term Effects
Other health effects may show up years after exposure has occurred, or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.
 
While pollutants commonly found in indoor air are responsible for many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems. People also react very differently to exposure to indoor air pollutants. Further research is needed to better understand which health effects occur after exposure to the average pollutant concentrations found in homes, and which occur from the higher concentrations over short periods of time.
 
In summary, indoor air contaminants can be a source of ill health. Hire an InterNACHI inspector trained in air quality to perform your next home inspection.

Ten Things You Should Know About Mold

 
 1.  Potential health effects and symptoms associated with mold exposure include allergic reactions, asthma, and other respiratory complaints. 
 
 2.  There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
 
 3.  If mold is a problem in your home, you must clean up the mold and eliminate sources of moisture.
 
 4.  Fix the source of the water problem or leak to prevent mold growth.
 
 5.  Reduce indoor humidity (to 30% to 60%) to decrease mold growth by: 
a. venting bathrooms, dryers, and other moisture-generating sources to the outside;
b. using air conditioners and de-humidifiers;
c. increasing ventilation; and
d. using exhaust fans whenever cooking, dishwashing, and cleaning.  
 6.  Clean and dry any damp or wet building materials and furnishings within 24 to 48 hours to prevent mold growth.
 
 7.  Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials that are moldy (such as carpeting and ceiling tiles) may need to be replaced. 
 
 8.  Prevent condensation.  Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof and floors) by adding insulation. 
 
 9.  In areas where there is a perpetual moisture problem, do not install carpeting.
 
10.  Molds can be found almost anywhere; they can grow on virtually any substance, provided moisture is present. There are molds that can grow on wood, paper, carpet, and foods.
