Working with a number of developers/end users and different project teams, it is clear that ‘the interpretation’ of Lab Definitions is not set in stone.
In response, we have looked at the different labs and identified, in a simple and clear way.
- ‘Wet’ v ‘Dry’ differences.
- Different ‘Wet’ lab containment level variances.
- Key design implications associated with each lab requirement.
- The construction cost drivers for each definition.

Why we think clear definitions are important?
Early communication is key to ensuring the right end product is achieved and costs are optimised efficiently.
Understanding the core definition is fundamental to setting the key design requirements and cost drivers.
Know your safety cabinets...
Microbiological Safety Cabinets (MSC) classifications are separate from and do not correspond to Containment levels.
It is important to have a good sense of which cabinet your facilities may need. This classification affects air filtration systems associated with the cabinet type and potentially wider HVAC coordination.

Class I and II Can be Recirculating or Non-recirculating: This is more fundamental to Shell and Core design than the class of cabinet.
