What are the federal standard dust lead hazard levels for wipe sampling on floors?

The federal standard dust lead hazard level for wipe sampling on floors is set at 40 micrograms per square foot (µg/ft²). This standard was established to help protect public health, particularly the health of children, who are especially susceptible to the harmful effects of lead exposure. Keeping lead levels low in homes and environments where children play is critical because even small amounts of lead dust can pose serious health risks.

By establishing a threshold of 40 µg/ft², regulatory agencies aim to identify and remediate lead hazards to minimize exposure. This level is based on research linking lead dust exposure with physical and cognitive development issues in children. Awareness of this standard is crucial for lead safety professionals when conducting assessments and implementing remediation strategies to ensure environments are safe for occupants, particularly young children.
