Why is the year 1978 significant in lead-based paint regulations?

• A. It marks when XRF testing was introduced
• B. It marks when the AAS method was standardized
• C. It marks when the RRP rule was enacted
• D. It marks when lead-based paint was banned for residential use in the U.S.

Answer: (D)

The important point is that in 1978 the federal government banned the sale of lead-based paint for residential use. This ended the use of lead-containing paint in new housing, so today the primary lead hazards come from older buildings constructed before that ban. Regulations since then focus on identifying and mitigating those hazards during renovations and ensuring disclosure and safe abatements in pre-1978 housing. The other options describe testing methods or later rules that are not tied to that year; XRF and AAS are analytical techniques used to measure lead, and the Renovation, Repair, and Painting rule came much later to address renovation work.
