Which surface type is NOT considered when evaluating surface hazards associated with lead?

  1. Friction surfaces

  2. Chewable surfaces

  3. Impact surfaces

  4. Textile surfaces

The correct answer is: Textile surfaces

The correct answer is "Textile surfaces" because when evaluating surface hazards associated with lead, primarily hard surfaces where lead can accumulate and be ingested or inhaled are of the greatest concern. Friction surfaces, chewable surfaces, and impact surfaces are all types of surfaces that are likely to be associated with lead exposure. Friction surfaces can generate lead dust through normal wear and tear, chewable surfaces represent areas where children may put their mouths, potentially leading to ingestion of lead, and impact surfaces could be places where lead paint may chip or deteriorate upon impact. Textile surfaces, however, do not present the same immediate risk as they do not typically retain lead dust in a hazardous form nor are they usually settings where direct ingestion occurs. This differentiation is crucial for assessing lead risk effectively, as it helps focus efforts on the surfaces that pose a significant danger for lead exposure.
