If any employee becomes occupationally exposed to anyone with a known case of active tuberculosis (TB), and the employee subsequently develops a tuberculosis infection, the case must be recorded on the OSHA 300 Log by checking the respiratory condition column. 29 C.F.R. § 1904.11(a). Before the event is entered on the log, you should have a record of a positive skin test or a diagnosis by a physician or other licensed health care professional in hand.

You do not have to record the case if it can be determined that the employee was not occupationally exposed to a known case of active tuberculosis at the workplace. The case can be removed from the Log if you obtain evidence that the worker is living in a household with a person who has been diagnosed with active TB; the public health department has identified 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. 29 C.F.R. § 1904.11(b).
