Which of the following tasks can a lead abatement supervisor perform?

Writing clearance reports is a task that a lead abatement supervisor can perform because it falls within their responsibilities to ensure that lead abatement activities have been conducted properly and to document successful clearance of lead hazards. Clearance reports are important for verifying that a property meets safety standards following remediation efforts, and the supervisor's knowledge and authority enable them to accurately assess and report on these conditions.

In contrast, conducting XRF measurements, which require specific certification and skills in handling testing equipment, is generally performed by trained professionals who specialize in field testing or inspections. Performing inspections without any training is not permissible, as it places the safety of individuals at risk and can lead to inaccurate assessments of lead hazards. Lastly, conducting lead hazard screenings without supervision is also outside the scope of a supervisor’s responsibilities, as proper oversight is crucial for ensuring compliance with health and safety regulations.
