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.

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! Questions?
