Considerations for the selection of a generator as a back-up power source for an animal facility.

Loss of power, whether or not it is related to a disaster, is a potential problem for animal facilities. The lack of light and the inability to operate mechanical systems related to ventilation, security, access, water, sewer and environmental control; to use laboratory instruments and equipment such as cage-washers and automatic watering systems; and to access computers and electronic files, potentially including animal health records and environmental monitoring data, present substantial challenges to facility operation. Therefore, an animal research facility must develop a contingency plan to address loss of power and other potential threats. Use of a back-up power source such as a generator is a common component of such a plan. Here the author discusses factors that should be considered in the selection of a generator as a back-up power source for an animal facility.
