What should be recommended if encapsulation is used as a method for controlling a lead hazard?

When encapsulation is employed as a method for controlling a lead hazard, annual monitoring is recommended to ensure that the encapsulation remains intact and effective over time. Encapsulation involves sealing lead-containing materials with a protective barrier to prevent exposure to lead dust or paint chips.

Regular annual monitoring allows for inspections to check for any signs of deterioration or failure of the encapsulation materials. This helps ensure that the encapsulated lead hazards do not pose a risk to occupants or the environment. Continuous monitoring may not be required since encapsulation, when properly applied and maintained, should not require constant oversight. Immediate remediation or complete removal are more aggressive approaches that would typically be reserved for situations where encapsulation is insufficient to manage lead hazards safely or when conditions change, necessitating a different intervention. Thus, annual monitoring strikes a practical balance between safety and cost-effectiveness in managing encapsulated lead hazards.
