LABORATORY BIOSAFTEY IN EBOLA AND MAR BURG VIRUS SPECIMENS ,

Post graduate question in Microbiology - recent advances Given the nature of the work at the lab, CFIA said it's choosing stricter procedures to protect employees, including:
Enhancing the suit testing procedures.
Shortening the life cycle of suits to fewer than 5 years and even shorter for animal work.
Improving documentation and record keeping for entry/exit procedures from the lab.
Enhancing the training of bio containment Laboratory staff and improving the tracking system to monitor trainee BSL-4 builds upon the containment requirements of BSL-3 and is the highest level of biological safety. There are a small number of BSL-4 labs in the United States and around the world. The microbes in a BSL-4 lab are dangerous and exotic, posing a high risk of aerosol-transmitted infections. Infections caused by these microbes are frequently fatal and without treatment or vaccines. Two examples of microbes worked with in a BSL-4 laboratory include Ebola and Marburg viruses.
In addition to BSL-3 considerations, BSL-4 laboratories have the following containment requirements:
Laboratory practices
• Change clothing before entering.
• Shower upon exiting.
• Decontaminate all materials before exiting.
Safety equipment
• All work with the microbe must be performed within an appropriate Class III BSC , or by wearing a full body, air-supplied, positive pressure suit.
Facility construction
• The laboratory is in a separate building or in an isolated and restricted zone of the building.
• The laboratory has dedicated supply and exhaust air, as well as vacuum lines and decontamination systems.
