What is a common practice for handling lead-contaminated materials?

Handling lead-contaminated materials requires adherence to specific safety protocols to prevent exposure and environmental contamination. Enclosing or encapsulating contaminated materials is a standard practice because it minimizes the risk of lead dust dispersal and protects human health and the environment. This method involves securely covering or sealing the contaminated items in a manner that prevents lead particles from becoming airborne or affecting surrounding areas.

In contrast, the other options are not considered safe or effective practices. Discarding lead-contaminated materials in regular trash could lead to public health risks as lead can leach into the environment. Burning lead-contaminated materials can release toxic fumes and particulates, worsening environmental contamination. Using abrasive cleaning methods can create dust that further spreads lead contamination rather than containing it. Therefore, enclosing or encapsulating is the safest and most responsible approach to managing lead-contaminated materials.
