protection | TB
Local public health agency employees usually do not see cases of
suspected or known TB in their facilities. However, if someone who
states he/she has TB presents to a LHD for services, how should staff
manage that person?
The person should be asked to don a surgical mask immediately and be
escorted out of the facility for referral to a health care facility able
to provide appropriate infection control measures for TB patients. If
the client is not able to leave right away, he/she should be taken to a
private room until arrangements for departure can be made. Staff
entering the private room should wear respiratory protection (NIOSH
approved fit-tested N95 filtering face piece or PAPR). The client may
remove the mask once he or she is outdoors.
Once the room is empty, it should remain unoccupied with the door
closed for a period of time to allow the air to clear of infectious
particles. The CDC Guidelines for Preventing Transmission of TB (table
1) (Exit DHS) specifies the amount of clearance time required based
on the number of air exchanges that occur in the room per hour .
Contact your building maintenance staff if you do not already know
the air exchange rate of the room.
