That's why a plan for the organization at a major accident exceeds the simple task of only alarming additional forces. Every management requires organization and leadership. Especially in times of a crisis an additional need of immediate action arises and decisions have to be taken in a straight forward way. In case of emergency the alarm has to be quick and reliable. The competence to set the alarm in motion has to be settled as low as possible in the hierarchy.
Otherwise time is lost during early phases of the plan.
This time is decisive and will not be compensated anymore. In conclusion, alarm has to be given early and generously even upon mere suspicion of a major accident. Delayed mobilization is irreparable. A surplus of personnel can always be dismissed later at any time. Alerting must never be a privilege of the director of administration or to the head of the physicians.
