Clinical samples collected in COVID-19 patients are commonly manipulated in BSL-2 laboratories for diagnostic purpose. We used the French norm NF-EN-14476+A2 derived from the European standard EN-14885. To avoid the risk of exposure of laboratory workers, we showed that Sodium-dodecyl-sulfate and Triton-X100 must be added to guanidinium thiocyanate-lysis buffers to obtain a 6-log reduction of infectious virus. Heating protocol consisting of 92{degrees}C-15min was more effective rather than 56{degrees}C-30min and 60{degrees}C-60min to achieve 6-log reduction.
