BSO Biosafety level 3 BSL3 - Course for Biosafety Officers (BSO)

The demands on the BSO are high: they are the contact person for all questions of biosafety internally vis-à-vis colleagues and the management and externally vis-à-vis the authorities. BSOs ideally have a higher professional education, if possible with a university degree, comprehensive laboratory experience and knowledge of all biosafety issues. They have negotiating skills and assertiveness.

Biosafety has the purpose of protecting humans and the environment through the handling of genetically modified, pathogenic or alien organisms.

Since 1999, the Containment Ordinance and the Ordinance on the Protection of Workers against Risks from Microorganisms have regulated the handling of organisms, in particular genetically modified and pathogenic organisms. These ordinances require, among other things, that a person responsible for biological safety be designated for such activities, the so-called Biosafety Officer (BSO).

Course language

  • English

Taking into account the respective safety level, the organisms used and the technical equipment, a biosafety officer (BSO) is responsible for drawing up an operational concept for the biological safety laboratory based on the legal foundations, in cooperation with the bodies involved. He/she is responsible for information, awareness raising, further training and advice on biological safety for the staff working on the premises.
