Laboratory Biosafety Manual, Fourth Edition
The de facto global reference for laboratory biosafety. The fourth edition moves decisively from prescriptive containment levels to a risk- and evidence-based approach, in which facilities, equipment and work practices are chosen proportionate to an assessed risk rather than assigned by category.
Always verify against the current published text before relying on it for a submission or inspection.
Scope & applicability
Work with biological agents in laboratory and related settings, supported by seven subject-specific monographs. Its shift away from fixed requirements is the important one for regulated manufacture: containment is argued from a documented risk assessment rather than inherited from a biosafety-level label, which is the same reasoning GMP applies to contamination control.
Key requirements
- Risk assessment as the basis for control selection, replacing prescriptive assignment by containment level
- Core requirements applicable to all laboratories, with heightened and maximum containment measures added on assessed risk
- Good microbiological practice and procedure as the foundation regardless of containment level
- Personnel competence, decontamination and waste management, and incident response
- Seven associated monographs covering risk assessment, biosafety programme management and related topics
Implementation tips
- Containment and cleanroom design pull in opposite directions — negative pressure to protect people and environment, positive pressure to protect product — and a facility doing both has to resolve that by design rather than by procedure
- The risk-based framing means the assessment is the deliverable: a containment decision inherited from a biosafety-level label, with no documented assessment behind it, is exactly what the fourth edition moved away from
