What is the lead clearance value for windows according to EPA standards?

The lead clearance value for windows according to EPA standards is set at 100 μg/ft². This standard is critical in ensuring that lead dust levels in residential properties, particularly those with potential lead-based paint hazards, are kept to a minimum. The value of 100 μg/ft² indicates that any surface, such as a window sill, must not exceed this concentration of lead dust for a dwelling to be considered safe for habitation. This threshold is established to protect occupants, especially children who are more vulnerable to the harmful effects of lead exposure. Therefore, when determining lead clearance levels during inspections, the focus is on ensuring that any one of these areas meets this specific standard to safeguard public health.
