What year were the initial guidelines on lead exposure in public housing introduced?

The initial guidelines on lead exposure in public housing were introduced in 1996. This year marks a significant turning point in federal regulations concerning lead safety, particularly in the context of public housing. The introduction of these guidelines came in response to increasing awareness of the dangers posed by lead exposure, especially to children who are particularly vulnerable to its harmful effects. The guidelines established standards for assessing and mitigating lead hazards in public housing, emphasizing the need for proactive measures to protect residents. Therefore, 1996 is the correct choice as it represents the start of a regulatory framework aimed at reducing lead exposure in public housing environments.
