This standard gives biological, physical and procedural containment measures for work with genetically modified plants including plants where the transferred genetic material is derived from a non-plant source. It defines measures to minimize hazards identified by risk analysis. Containment may be provided in a greenhouse or in a growthroom, laboratory or other containment facility. Containment of genetically modified microorganisms and/or small animals associated with plants is not included in this standard. Containment of microorganisms is covered in EN 12128.
