In a well-functioning economic system the basic needs of the population and the business community are met. The state, too, can finance its operations. In exceptional conditions the authorities must control the economy with more powerful measures than usual to guarantee the well-being of citizens. This is achieved by decisions regarding state revenue and expenditure and the financial and insurance markets. If necessary, workforce is directed on a temporary basis to help in the aftermath of a major accident.
It is the responsibility of the authorities to ensure that transport and telecommunications function not only in normal conditions but also during disruptions and exceptional conditions. Energy, clean water and foodstuffs must be available in all times.
