On which surfaces does the Consumer Product Safety Commission restrict lead in coatings?

The Consumer Product Safety Commission (CPSC) implements regulations to limit lead exposure, especially in environments where children are likely to be present. This includes not just residential structures but also structures that are commonly accessed by the public. The correct answer encompasses all these critical areas—residential structures, buildings that are commercially accessed, and playground equipment.

Residential structures are an obvious target for regulation due to the presence of children who may be more susceptible to the dangers of lead exposure. Commercially accessed buildings expand this focus to places where safety concerns intersect with public health, ensuring that environments used by families and children are also monitored and regulated.

Playground equipment is specifically highlighted because it is an area where children often play, which increases the risk of lead exposure due to potential ingestion or contact with deteriorating lead-based coatings. Lead in these areas can have long-term health implications, reinforcing the importance of comprehensive regulations that cover a broad spectrum of public and private spaces where children are likely to be.

In summary, the correct answer reflects a comprehensive approach to lead safety, protecting children in multiple environments.
