Which of the following is considered a lead hazard?

A lead hazard is characterized by the presence of lead-based paint that is deteriorating or in a condition that poses a risk of exposure to lead dust or chips. Chipping or peeling paint is particularly concerning because it indicates that the paint is breaking down, which can release lead particles into the environment where they can be inhaled or ingested, especially by children and pregnant women who are most vulnerable to lead exposure.

In contrast, lead-based paint in good condition may not present an immediate hazard, as it is intact and not chipping or peeling. Lead-free paint and lead encapsulation are also not considered lead hazards; lead-free paint does not contain lead, while encapsulation is a method of sealing lead-based paint to prevent exposure, effectively mitigating the risk of a lead hazard. Therefore, chipping or peeling paint is definitively recognized as a lead hazard due to the potential for lead exposure it creates.
