1. The employer does not have to record a positive TB skin test result obtained at a preemployment physical because the employee was not occupationally exposed to a known case of active TB in your workplace.
2. The employer may line-out or erase a TB case from the log under the following circumstances:
a. The worker contracted TB while living in a household with a person who had been previously diagnosed with active TB;
b. 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
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.
