Which federal act was aimed at reducing lead-based paint hazards in residential properties?

The Residential Lead-Based Paint Hazard Reduction Act was specifically designed to address lead-based paint hazards in residential properties. This act establishes requirements for the disclosure of known lead-based paint and lead-based paint hazards in housing, particularly for properties built before 1978, when lead-based paint was banned for residential use. The act aims to protect the health of residents, especially young children and pregnant women, who are most vulnerable to the harmful effects of lead exposure.

The other options, while all related to lead safety or housing issues, do not specifically target lead-based paint hazards to the same extent as the Residential Lead-Based Paint Hazard Reduction Act. For instance, the Lead-Based Paint Poisoning Prevention Act is focused on the prevention of lead poisoning but does not encompass the same range of duties regarding hazard reduction in residential properties. Similarly, the Housing and Community Development Act and the Childhood Lead Poisoning Prevention Act address broader housing and health policy issues but are not specifically aimed at reducing lead-based paint hazards. The targeted focus of the Residential Lead-Based Paint Hazard Reduction Act makes it the most appropriate answer for this question.
