After what year is it considered safe to conduct renovation and demolition activities concerning lead?

  1. 1980

  2. 1978

  3. 1985

  4. 1990

The correct answer is: 1978

The year 1978 is significant in the context of lead exposure and safety regulations because that is when the United States banned the use of lead-based paints in residential properties. This was a pivotal moment in addressing lead hazards, especially for children who are most vulnerable to lead poisoning. As a result, any renovation and demolition activities in buildings constructed before this date require careful management and safety protocols to minimize lead exposure risks. Conducting such activities in properties built before 1978 necessitates appropriate precautions, including lead hazard assessments and remediation strategies. Post-1978, while it is considered safer regarding lead content in new paint, precautions are still necessary for older structures.
