Question

Quizplus · Accepted Answer

Homes built before 1970 were often constructed with asbestos-containing materials such as roofing shingles, insulation, and siding. Asbestos can cause serious health problems if the fibers are inhaled, so homeowners should be aware of the potential risks and take measures to minimize exposure. Carbon monoxide, formaldehyde, and hydrogen chloride are also potential contaminants that can be found in homes, but they are not typically associated with construction materials in older homes.
