The triage nurse should be specifically trained to recognize signs and symptoms of possible active pulmonary tuberculosis. If TB is suspected, the patient should be placed on Airborne Precautions (i.e. in a negative pressure respiratory isolation room with the door closed). In the event, a negative pressure isolation room is not available, the patient should wear a N-95 respirator in a private room with the door closed. The prompt recognition of suspected TB and the appropriate evaluation using Airborne Precautions is essential in avoiding possible nosocomial exposure to tuberculosis.
	Patients with confirmed or suspected TB should wear a N-95 respirator when out of the isolation room for diagnostic procedures. If a patient is uncooperative or unable to wear a respirator, the healthcare worker should wear a N-95/HEPA respirator when in close proximity to the patient.
	Ventilation in emergency rooms, including waiting areas should be designed and maintained to reduce the risk of the transmission of tuberculosis. The American Society of Heating, Refrigerating, and Air Conditioning Engineers, Inc., (ASHRAE) recommends that emergency room waiting areas have at least ten air exchanges per hour.
	When emergency medical response personnel or others must transport patients with confirmed or suspected TB, a N-95 respirator should be placed on the patient. Because administrative and engineering controls during emergency transport cannot be ensured, the transporting personnel should wear N-95/HEPA respirators. If feasible, the windows of the vehicle should be kept open. The heating and air conditioning system should be set on a non-recirculating cycle.
