There are several BSL-3
in Saudi Arabia and I think they are building one in Jordan and the UAE.
Traditionally, the air within a BSL-3
laboratory is changed eight to 12 times per hour, but it isn't uncommon to find the heat load from the equipment within drives the air exchange rate higher.
BSL-4 builds upon the containment requirements of BSL-3
and is the highest level of biological safety.
BSL-4 laboratory orientation training assumes that the person has already mastered all procedures for safe and secure handling of infectious agents at the BSL-2 and ideally BSL-3
A major proliferation of high-containment BSL-3
and BSL-4 labs is taking place in the United States, according to the literature, federal agency officials, and experts.
The Ukraine BSL-3
laboratory is the first to be commissioned in the Former Soviet Union under the Nunn-Lugar Global Cooperative Threat Reduction Program.
Maybe Washington, DC, the city has no facilities (I don't know that they don't nor do I know what the universities have), but I can assure you that the Washington, DC, area has fully operational containment facilities operating at BSL-3
facilities must be isolated from other areas having open access.
Determining what work or projects require BSL-3
CUH2A architects, engineers and planners specialize in science and technology projects and have designed over 50 high-containment BSL-3
and BSL-4 facilities to handle the most lethal pathogens.
CBI is accredited by the American Association of Blood Banks, CLIA, and the National Forensic Science Technology Council, and operates fully accredited BSL-3
He designs highly-adaptable engineering systems for open laboratories to easily accommodate scientific and technological advancements as well as engineering systems for laboratories with higher levels of hazard; including BSL-3
Enhanced, BSL-Ag and BSL-4.
