Fires, floods, and system failures in research facilities can kill thousands of laboratory animals — welfare preparedness and rapid response are essential.
Research facility disaster welfare requires pre-planned responses rather than improvised ones. In acute disasters, the welfare-optimal response for individual animals may be rapid euthanasia rather than attempted rescue — preventing prolonged suffering from smoke inhalation, drowning, or heat stress. This requires pre-authorised emergency euthanasia protocols, training of animal care staff in emergency response, and genuine incorporation of animal welfare in facility disaster planning. The psychological impact on staff who perform emergency euthanasia of thousands of animals in a crisis requires institutional support. Preventive engineering — fire suppression systems, flood barriers, backup ventilation — reduces the frequency of these events.
