The WIMM has a contingency plan that is updated annually. This covers fire, loss of power, pandemic flu, flood and explosion. In the event of a freezer breakdown there are contingency plans in place see WIMM E002 Freezer breakdown and emergency procedure and WIMM E014 Transfer of freezer contents in the event of a freezer breakdown. It is the responsibility of individual groups to make certain that they maintain their freezers and do not allow them the freeze up. Freezers need to be well organized such that in the event of a freezer breakdown the Buildings Manager and his assistant can safely and easily transfer the contents from an ailing freezer to an emergency freezer. Liebherr freezers with solid plastic freezer drawers are preferred for long-term storage at -20oC.
