Freezer Management 2001
• Freezers in various locations.• Not all alarmed.• Call-out procedures unclear.• No regular maintenance.• No emergency decant space.• No clear sample management.
![Page 11: COLD STORAGE AND L ABORATORIES](https://reader035.vdocuments.mx/reader035/viewer/2022062315/5681656b550346895dd7fcbe/html5/thumbnails/11.jpg)
Change
• Freezer locations centralised + alarmed• Dedicated freezer team appointed• Standard Operating Procedures introduced• Daily temperature monitoring• Regular defrosts• Quality Assurance Management input-sample
tracking--easy to use sample tracking encourages uptake of use!

IMPACT
• Efficient use of lab space- equipment and cooling .
• Efficient use of internal Freezer Space.• Easier to identify available freezer space.• Reduction in number of freezers. • Increased sample security. • Risk Register level reduced.

Steps to improvement
• Replace inefficient fridges and freezers. • Encourage sharing-making user cost aware!• Utilise climate to help cool Freezer rooms.• Manage sample tracking –user friendly.• Maintain Freezers and Alarms. 2 visits/year.• Consider -20 walk-in rooms over multiple -20
chest freezers. (20% saving )• Encourage temperatures at -70 over -80

To Do List
• Metering of cooling within freezer rooms- raise cost awareness.
• True archive freezers removed to a secure and efficiently designed building(Freezer Farm)-this would release prime space within buildings to allow either expansion or consolidation!
