Overview
Frequently asked questions about bio-specimen freezer storage.
Q: What is the backup plan in the event of a power outage?
A: Backup power is supplied by a pair of 125kW diesel generators with automated switchgear that requires no human intervention. In the event of a loss of power to the facility, the generators will sense the loss of power and start supplying power to the Freezer Farm only. Should the generators stop running due to a loss of PG&E power, the University of California Police Department (UCPD) will receive an alarm signal and contact Logistics staff. The generators have approximately 300 gallons each of diesel fuel on board, and even with all -80°C freezers running continuously, the available fuel represents a 72+ hour supply, which exceeds NIH requirements. These generators are inspected each week, test run every 30 days, run under a minor load each quarter, and run under a full load annually.
Q: How do I know if my samples are safe?
A: Logistics works closely with Freezer Farm customers to assure that all samples stored at Oyster Point receive the same level of support as samples stored in the customer's lab. Our staff monitor and record the temperatures of all freezers every morning and evening of each business day. We also collect environmental data for the air temperature in the Freezer Farm. Our staff is skilled in handling liquid nitrogen in the event that you use that type of freezer.
Q: Are there other methods that I can check the contents and conditions of the freezers?
A: In the event that a customer notices a temperature excursion in one of their freezers overnight, on a weekend or a holiday, we ask that they contact UCPD at (415) 476-1414. UCPD maintains a list of available Logistics staff, and they begin calling them. Once UCPD reaches an available staff member, they pass on the customer's contact information. At this point Logistics staff will make arrangements to meet the customer at Oyster Point to move samples to another freezer.
