Final answer:
The lead-based paint disclosure requirements are specific to houses built before 1978, the year lead-based paint was banned for use in housing. Older homes are particularly at risk for containing lead-based paint, and renovations can release hazardous lead dust, highlighting the importance of professional lead hazard management.
Step-by-step explanation:
The lead-based paint disclosure requirements apply to houses built before 1978. This is because lead-based paint was banned by the U.S. government for use in housing that year.
Evidence from the Environmental Protection Agency (EPA) demonstrates high prevalence of lead-based paint in older homes, with 87% of homes built before 1940, and 69% of homes built between 1940 and 1959 containing it. Only 24% of homes from 1960-1977 have lead-based paints.
The threat of lead exposure becomes significant due to activities like sanding or renovations that disrupt the underlying paint and release lead dust. Ingestion or inhalation of this dust can lead to lead poisoning, especially in children, such as the case study presented with Lucas. It's crucial to inspect older homes for lead and manage any identified hazards professionally to prevent health risks associated with lead exposure.
