In emergency situations like Three Mile Island and Deepwater Horizon, the significance of alarm design is evident. Poorly designed alarms hindering communication and causing confusion can exacerbate the severity of accidents. When an excessive number of alarms go off simultaneously, it impedes effective responses. In the case of Deepwater Horizon, alarm systems were deliberately inhibited to prevent false alarms, ultimately leading to a disastrous outcome. These incidents highlight the critical role of alarm design in maintaining safety and preventing accidents.
