The correct answer is based on regulations set forth for workplace safety, particularly concerning exposure to hazardous materials such as lead. Employees have the right to medical examination and consultation if they will work with lead at or above the action level for more than 30 days per year.

This is designed to protect workers who are potentially exposed to lead at levels that could pose health risks. The action level indicates a specific concentration of lead in the air, which, if reached or exceeded, requires employers to implement certain safety measures, including providing medical evaluations.

By ensuring that employees who meet this criterion are eligible for medical examinations, regulations aim to monitor and safeguard their health based on the nature and duration of their exposure. This proactive approach is essential for early identification of any potential health effects related to lead exposure.
