Which of the following is NOT a job discipline related to lead investigations?

The role of a building contractor is not specifically focused on lead investigations, which primarily target the assessment, evaluation, and management of lead hazards. Building contractors are primarily concerned with construction and renovation work rather than directly addressing lead hazards or conducting assessments to determine the presence of lead in properties.

In contrast, a lead hazard investigator, lead risk assessor, and lead paint inspector are specifically trained professionals who conduct detailed evaluations of properties for lead-based paint and other lead hazards, assess risk levels, and ensure compliance with health regulations regarding lead exposure. These roles involve specialized skills and knowledge relevant to identifying and mitigating lead risks, making them distinct career paths within public health and safety, particularly regarding lead exposure.
