What defines a lead hazard?

A lead hazard is defined as any substance containing lead that has the potential to contribute to exposure. This definition encompasses a wide range of situations and materials where lead may be present and poses a risk, not just limited to specific forms or locations. It recognizes that exposure can occur through various mediums, such as paint, dust, or soil, particularly in environments where lead has been used historically.

While painted surfaces and their deterioration can certainly be lead hazards, solely considering paint or dust would exclude other significant sources of lead exposure. For instance, lead can be found in older plumbing systems, imported toys, and certain types of ceramics, all of which fall under the broad definition of substances containing lead that could lead to health risks. Thus, the comprehensive understanding of what constitutes a lead hazard is crucial for effective risk assessment and management.
