What year is commonly used as a reference point for pre-1978 housing in lead hazard contexts?

• A. 1978
• B. 1984
• C. 1990
• D. 2000

Answer: (A)

The year commonly used as a reference point for pre-1978 housing in lead hazard contexts is 1978. This is because lead-based paint was banned for residential use in 1978, so homes built before that year are considered to have a higher likelihood of containing lead-based paint. That cutoff provides a straightforward screening category for risk assessments and mitigation efforts. While lead hazards can exist in homes built after 1978 from other sources, the pre-1978 threshold remains the standard marker used to identify higher-risk housing.
