What is a surface that is 0.5% or more lead by dry weight categorized as?

A surface that contains 0.5% or more lead by dry weight is categorized as a dangerous surface. This classification is based on safety regulations regarding lead-based materials, particularly in the context of lead inspections and risk assessments. Lead is a toxic substance, and surfaces with this level of lead concentration pose a significant risk, particularly to children and pregnant women, who are more vulnerable to the harmful effects of lead exposure.

The categorization as a dangerous surface indicates that appropriate measures must be taken to address the risks associated with lead exposure, which may include remediation, containment, or other protective strategies to minimize contact with the hazardous material. This standard is crucial in ensuring health and safety, as surfaces with such a lead content can lead to elevated blood lead levels and other serious health consequences.

In contrast, classifications like compliant, safe, or removable do not accurately reflect the risks associated with a surface that has such a high lead content. Compliant and safe surfaces would typically contain lead at levels below the threshold that poses a health risk, while a removable surface might imply that it can be easily taken away or replaced, which is not necessarily the case with a dangerous surface that requires controlled remediation.
