WHO Laboratory Biosafety Manual: A New Approach to Security

The paper aims to highlight the new indications introduced in the 4th edition of the “Laboratory Biosafety Manual” of World Health Organization. The authors propose a new vision to improve biosafety and biosecurity in the laboratory aligned with the technical standards ISO 35001:2019 “Biorisk management for laboratories and other related organizations” and ISO 45001:2018 “Occupational health and safety management systems—Requirements with guidelines for use” framework. The current edition has a more innovative approach compared to the previous ones, more attention is given to training awareness and providing skills, to promote the culture of safety by adopting an approach based on risk analysis, rather than the prescriptive approach that has been used previously.
