HEPA (high-efficiency particulate air) filters in series, personal protective equipment (PPE; such as the one-piece encapsulated suit), SOPs (such as special decontamination processes), and administrative controls (for example, training requirements and medical surveillance enhancements). The proposed new USAMRIID facility will include BSL-3 and BSL-4 laboratories.
The Army has been a leader in developing cutting-edge requirements for high- and maximum-containment laboratories. As new containment laboratories have proliferated across the country in recent years, there has been a steady development of better facilities, increasingly robust biosafety practices and procedures, and a continuing cross-fertilization of new technologies. With this development has come a significant reduction in laboratory-acquired infections at USAMRIID and at other biocontainment facilities (Rusnak et al. 2004a).
