Remodeling by-products. Remodeling can provide the disturbance that releases such materials as asbestos, lead, formaldehyde, and other hazardous materials.
Check out the Remodeling Hazards or Home IAQ Overview Instructional Modules from our Training Manual for more information, or read some Q&A below.

You may not have realized that your remodeling project may be creating unhealthy household air. To protect yourself and your family from these remodeling hazards, read on.

Q: By remodeling with products that don't include these hazardous materials, won't that minimize my exposure?
A: Not necessarily. Lead and asbestos were commonly used in home building until the late 1970s. Remodeling or attempting to remove these materials from a building can actually increase your risk of exposure. Often it's better to leave the lead- or asbestos-containing materials in place, but cover or seal them to reduce exposure. If you suspect these materials are in your home, seek professional help before remodeling. If you remodel, remember that careful clean-up is important to control exposure. 

Q: What is asbestos and why should I be concerned about it?
A: Major sources of asbestos are deteriorating, damaged or disturbed insulation, fireproofing or acoustical materials, and floor tiles. You won't feel any immediate symptoms from excessive asbestos exposure, but there is the long-term risk of chest and abdominal cancers and lung disease. Smokers are at higher risk of developing asbestos-induced lung cancer. 

Q: Why should I be concerned about lead?
A: Young children (up to about six years old) are especially at risk of unknowingly ingesting lead contaminated dust or paint chips. Small amounts of lead dust, ingested regularly, can cause delayed development, reading and learning problems, lowered IQ, hyperactivity and discipline problems. Larger doses can cause high blood pressure, anemia, and kidney and reproductive disorders in both kids and adults. Lead accumulates in the body and its effects are irreversible. 

Q: What is formaldehyde and why should I be concerned?
A: Formaldehyde is often used as a preservative or as an adhesive in pressed wood products, such as paneling and particle-board, and furniture.

Formaldehyde causes eye, nose and throat irritations; wheezing and coughing; fatigue; skin rashes; headaches; loss of coordination; nausea; damage to liver, kidneys and the central nervous system; and severe allergic reactions. It has been linked to cancer. 

Q: What about other chemicals used in remodeling, such as paints, wood strippers and finishes, adhesives, waxes and cleaners?
A: The products to watch for are those containing volatile organic compounds (VOCs), which are organic solvents that easily evaporate into the air. Some may be flammable. Following are some of the compounds listed on product labels: petroleum distillates, mineral spirits, chlorinated solvents, carbon tetrachloride, methylene chloride, trichloroethane, toluene and formaldehyde. Other remodeling products can be a hazard if they are used improperly. 

Q: Where can I get more information about safe remodeling practices?
A: Contact your local Extension Office or your state department of health. Take action now.
