Services that cannot be rendered in the patient's room are provided in an area that meets the requirements for an AFB isolation room.

Elective high-hazard procedures and surgery are delayed until the patient is non-infectious.

### High-Hazard Procedures

High-hazard procedures (where TB may be aerosolized) require precautions to prevent/minimize occupational exposure to infectious TB. The following high-hazard procedures are performed at this facility (List of procedures):

### Engineering Controls Maintenance Schedules and Records

The maintenance schedule for engineering controls is as follows:

- ● pressure areas are qualitatively demonstrated by using smoke trails. ● pressure areas are qualitatively demonstrated by using smoke trails.
- ● HEPA filters are changed, the system is inspected, and its performance ● HEPA filters are changed, the system is inspected, and its performance monitored in accordance with current USPHS guidelines. HEPA filters are changed every \_\_\_\_\_\_\_\_\_\_\_ in this facility or whenever \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_.
