Tuberculosis Reporting Criteria

If any of your employees has an occupational exposure to anyone with a known case of active tuberculosis (TB), and that employee subsequently develops a tuberculosis infection, as evidenced by a positive skin test or diagnosis by a physician or other licensed health care professional, you must record the case on the OSHA 300 Log by checking the "respiratory condition" column ((M)(3)).

Record TB as a respiratory disease.

Do not record a pre-employment positive skin test because the exposure was not in your workplace. Line out or erase a recorded case if you prove that:

  • the worker lives in a household with a person diagnosed with active TB;
  • the Public Health Department identifies the worker as a contact of an individual with a case of active TB unrelated to the workplace; or
  • a medical investigation shows that the employee's infection was caused by exposure to TB away from work, or proves that the case was not related to the workplace TB exposure.
