Safety Issues

• Fume cupboard and Safety cabinet discharges - External CFD Analysis

• Category 3 laboratory – MAT Packaged System utilising Tri MAT MBSCs

• Tissue Culture Rooms – Thimble System with room under negative pressure

• Variable air volume (VAV) systems – Econ system controlled to maintain room under negative pressure

• Chemical storage cabinets – operate 24 hrs/day using separate extract system

• Liquid Nitrogen dewar filling store – purge ventilation activated using oxygen depletion alarm system

• Carbon dioxide(CO2) and Argon bottle manifold room – oxygen depletion alarm system

• Natural gas - gas detection and pipe pressure testing/ alarm systems

• Drainage from radioactive labs – separate identified waste direct to external underground drainage

• Fume extract from radioactive labs – discharge via safe change HEPA filter

• Fire strategy and smoke ventilation – fire fighting lift, dry riser and basement smoke ventilation system

• Future operation and maintenance – sufficient space for maintenance and plant replacement strategy agreed

Used Pharmaceutical type testing and commissioning systems using Installation Qualification (IQ) and Operational Qualification (OQ) check systems/ paperwork.

IQ Check List

• Static Pressure testing of all pipework systems

• To verify that the ‘As Installed’ drawings are complete and accurate

• To check the standard of workmanship

• Check calibration of all sensors




OQ Testing

The purpose of OQ will be to confirm that the various mechanical system installations perform to meet the original design criteria.

The procedure required the contractor to spend sufficient time along with the WYG M&E to verify the performance of systems and included:

• Verification of ventilation air change rates

• Checking the performance of cooling systems using heat load tests

• Checking room temperatures

• Checking humidity levels where air conditioning is installed

• Verifying temperatures, flow rates and operating pressures of specialist systems (eg chilled water systems)

• Simulation of different scenarios to prove operation of BMS controls

• KI discus and DOP test of safety cabinets of safety cabinets

• Cause and Effect Testing relating to Fire Alarm

• Electrical Main incomer shut down/ elect standby generator

• 3 day Steady state running
