When should you call in an industrial hygienist in mold remediation projects?

In mold remediation projects, calling in an industrial hygienist after completing the project is typically most appropriate for ensuring that the remediation has been effective and that the environment is safe for re-occupation. An industrial hygienist can conduct post-remediation assessments, which may include air sampling and surface testing, to confirm that mold levels are within acceptable limits and that there are no lingering health risks associated with mold exposure.

Bringing in an industrial hygienist at this stage allows for an objective evaluation of the work done, helping to verify the integrity of the remediation effort. This ensures that all potential sources of mold have been addressed properly and provides reports that may be necessary for regulatory compliance or to reassure occupants that the space is now safe.

By contrast, calling the hygienist at other stages, such as before or during the project, may not provide the necessary assessments regarding the effectiveness of the remediation process itself. Involvement at these stages can be beneficial for planning purposes or risk assessment but does not replace the thorough evaluation needed to confirm completion of the remediation efforts.
