a) Basic Requirement

If any employee has been occupationally exposed to anyone with a known case of active tuberculosis (TB), and that employee subsequently develops a TB infection, as evidenced by a positive skin test or diagnosis by a physician or other licensed health care professional, record the case on the OSHA 300 Log by checking the respiratory condition column.

b) Implementation

1. 1) A positive TB skin test result obtained at a pre-employment physical does not need to be recorded because the employee was not occupationally exposed to a known case of active TB in the workplace.

2. 2) If the employer obtains evidence that the case was not caused by occupational exposure, the employer may line-out or erase the case from the Log under the following circumstances:

   1. A) The worker is living in a household with a person who has been diagnosed with active TB;
   2. B) The Illinois Department of Public Health has identified the worker as a contact of an individual with a case of active TB unrelated to the workplace; or
   3. C) 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.
