The use of safety equipment combined with good practices is fundamental to laboratory safety and in helping to reduce the risks involved in dealing with biosafety hazards. According to Article 4.84 of the Working Conditions Decree, the inactivated virus particles can be classified as category 1 of the biological agents<ref name="Arti30">1Short manual for theMLthe ML-I, ML-II laboratory(gmo-labs) and/or laboratory for working with biological agents / human materials, University of Twente, 2018,https://www.utwente.nl/.uc/f4fcab199010209618400ac90d20284e61d13c337a78900/short-manual-gmo.pdf</ref>, as they are unlikely to cause disease in humans. Therefore, only the biosafety guidelines as defined in the ML-1 (minimum containment level) have to be followed. It is stipulated in the guidelines that general laboratory protocols such as the usage of barrier protection (lab coats, gloves and face protection) when handling the samples are to be followed. The protection barriers are not always necessary from a microbiological perspective. However, it is compulsory when handling disinfectants or solvents.
