If a worker reports ear pain immediately before audiometric testing, what should the OHC do?

Ear pain may indicate a medical condition that could affect test validity or require treatment, so the worker should be seen by a physician first.
To maintain CAOHC certification, an OHC must demonstrate competency in which areas?
Answer: All CAOHC-defined core competencies including audiometric testing and HCP administration
CAOHC defines specific core competencies that all certified OHCs must maintain, covering audiometric testing, HPD fitting, HCP administration, and related areas.
When an OHC is uncertain whether an audiometric result is valid due to inconsistent responses, what is the best course of action?
Answer: Consult the supervising audiologist or physician for guidance
Questionable or inconsistent audiometric results should always be escalated to the supervising professional who can evaluate validity and determine next steps.
When a worker repeatedly refuses to wear required hearing protection, how should an OHC properly handle the situation?

Documenting HPD refusals creates an official record, protects the employer's compliance position, and enables follow-up action by the appropriate supervisor.
