The safety conditions of a Level 3 facility is characterized by “negative air pressure” (Preston, 1994, p. 175). This prevents leakages from any tube or lab equipment. The Level 3 facility also does not require a space suit upon entering. Instead the people who are working in the Level 3 facility dress “themselves like surgeons in an operating room” (Preston, 1994, p. 175). The people wear “a paper surgical mask, a surgical scrub suit, and rubber gloves” (Preston, 1994, p. 175). The laboratory is supervised by scientists who are experienced with the agents. All work in the lab is done by using physical containment devices. The filtered exhaust air in the Level 3 laboratory room in discharged outdoor. The ventilation in the laboratory room is balanced for a directional airflow into the room (McLeod, 2010). The laboratory is not accessible during working times. The Level 3 containment laboratory needs to meet the precautions necessary to isolate any agent that may be or cause serious or/ and fatal diseases in humans. However there must be treatments available for those diseases. The factory is designed to have self-closing double-door access (McLeod, 2010). McLeod, V. (2010, December 9).

Negative air pressure is when "more air is mechanically exhausted from a room than is mechanically supplied" (Negative Room Pressure to Prevent Cross-Contaminantion).The reason the Level 3 facility of the research center is under negative pressure is to "prevent things from leaking out" (Preston 175). Basically, if there were any sort of possible site for air diffusion, there would be a suction of air, instead of a release. When you present a negative with a positive, the negative basically decreases in negativity. The "imbalance" (Negative Room Pressure to Prevent Cross-Contaminantion) in pressures inside the room and outside of it cause there to be a flow of air until equilibrium is reached. This is important, especially in this specific situation, because ebola is airborne. It can travel on specks of dust or particles of water vapor. Exposing the outside world to even the air inside the room could potentially cause a huge outbreak and an even bigger panic.
