• The French decree of July 16, 2007 laying down the technical preventive measures, including containment, to be implemented in research laboratories, teaching, analysis, anatomy , surgical pathology, autopsy rooms, industrial and agricultural establishments where workers are likely to be exposed to biological pathogens.

Finally we used the international recommendations of the World Health Organization.
