Final answer:
The EPA/HUD pamphlet must be provided for all properties built before 1978 as they may contain lead-based paint, which poses a risk of lead poisoning.
Step-by-step explanation:
The EPA/HUD "Protect Your Family From Lead In Your Home" pamphlet must be provided for all properties built prior to 1978. Lead-based paint was commonly used in homes and was only banned by the U.S. government for use in residential properties starting in that year.
Many homes built before 1978 therefore have the potential to contain lead-based paint under newer layers. When renovations or deterioration occur in these older homes, lead paint and associated dust can be exposed, posing a risk of lead poisoning, especially to young children like the case of Lucas mentioned in the referenced text.
It is crucial for families living in these older homes to be aware of the risks and take appropriate steps to prevent lead exposure, which can include hiring lead-safe certified professionals for renovation work, frequent cleaning to minimize dust, and ensuring a balanced diet that can help inhibit the absorption of lead.
