Lead-based paint hazards are especially a concern in housing built before which year?

• A. 1960
• B. 1970
• C. 1978
• D. 1985

Answer: (C)

Lead-based paint hazards are most a concern in housing built before 1978 because that’s when residential lead-based paint was banned from sale. Before 1978, many paints contained lead, so homes erected earlier often still have lead-based paint on walls, trim, and windows. When that paint chips or deteriorates, or is disturbed during renovations, lead dust or chips can be ingested, posing serious health risks especially to children. After 1978, new residential paint generally didn’t contain lead, so newer homes are less likely to have lead-based paint, though hazards can remain if old materials haven’t been removed or properly contained.
