biological hazard symbol be presented as well as a major message (e.g.;
“special respiratory isolation,“ “Respiratory isolation,” or AFB isolation).
A description of the necessary precautions, e.g., respirators must be
donned before entering. Respiratory isolation rooms in an emergency
department or a message referring one to the nursing station for
instruction must also be posted.

b. The employer shall also use biological hazard tags on air transport
components (e.g., fans, ducts, filters) which identify TB hazards to
employees associated with working on air systems that transport
contaminated air (See Appendix A, page 85).

c. The standard provides in part:

29 CFR 1910.145(e)(4): Biological hazard warning signs were not used
to signify the actual or potential presence of a biohazard and to identify
equipment, containers, rooms, materials, experimental animals, or
combinations thereof, which contain, or are contaminated with viable
hazardous agents:

Sample violation language:

a. On or about [date], warning signs posted outside respiratory
(Respiratory) isolation or treatment rooms did not state the entry
requirement of wearing HEPA filtered respirators.

Abatement Note: Warning signs must be posted on respiratory
isolation or treatment rooms stating “pulmonary isolation,” “respiratory
isolation,” or “AFB isolation.” The sign must state specifically the
precautions required to interact with those patients. Indicators on
patient records or tags on corpses, printed in language or symbols easily
recognized by employees are additional methods to achieve this
purpose.

5. OSHA 200 log - 29 CFR 1904:

a. For OSHA Form 200 record keeping purposes, both tuberculosis
infections (positive TB skin test) and tuberculosis disease are recordable
in the high risk setting referenced in section H.1. A positive skin test for
tuberculosis, even on initial testing (except pre-assignment screening) is
recordable on the OSHA 200 log because there is a presumption of
work-relatedness in these settings unless there is clear documentation
that an outside exposure occurred.

Note: In this case pre-assignment means the same as pre employment
and initial testing is the same as baseline testing.

b. If the employee’s tuberculosis infection which was entered on the OSHA
