Process control: a practical example

BioSafety Level 4 – the highest safety level for genetic engineering has special technical requirements, e.g. regarding the airlock system.

Leaving the laboratory is only possible after a special decontamination process. The chemical composition of the decontamination solution (e.g. peracetic acid) may change with time, therefore continuous monitoring of the composition and correct additional metering are necessary.To guarantee the safety of both personnel and environment the system must be absolutely reliable. The Briem air lock control concept includes access control, process control, room monitoring and control of the chemical metering unit, operated by means of a user-friendly, multi-lingual user interface.In the risk analysis, compiled before begin of the project, the risk factors were evaluated and during the planning appropriate measures to minimize the risks were implemented, e.g. redundant ultrasonic sensors for monitoring the filling level of the decontamination tanks. The functionality of each part was trialed intensely (e.g. during the factory acceptance test/FAT).We accompanied this project from the functional concept, during planning and production to commissioning.
