Results from WS 2: supply.

Rank	Field	Risk/crisis	Description
1	Supply	Loss of power for more than 48 hours	There is a power failure lasting longer than 48 hours. The propellant and thus the emergency power supply cannot be maintained over the entire duration of the power failure. It comes to a gradual failure of all supply elements (e.g., hot water, heating, and cooling) and communication (within and outside of the hospital). The treatment can be carried out only in a severely restricted way or not at all.
2	Supply	Heating/air falls out: evacuation necessary	Due to a failure of the heating or cooling system, an evacuation of the hospital is necessary. In consequence of a very short time frame and the threat of patient risk, an immediate action is needed. It comes to a mismatch between existing and required human resources. Scheduled treatment cannot take place and the hospital is no longer accepting patients.
3	Supply	Fire (smoke on ward)	A fire spreads out at a unit with the consequence of smoke and fire damage. Patients and staff are at risk. The unit has to be evacuated.
4	Supply	Failure of the water supply	In health care facilities such as hospitals, the availability of drinking water is essential to survive. A supply of water in the hospital cannot be ensured. The use of sanitary units and the execution of cleaning operations are no longer possible. While the remedy no medical processes can take place. Depending on the duration and extent of the failure, the hospital has to be evacuated.
5	Supply	Spills of dangerous substances (e.g., chlorine gas)	In many functional units of the hospital hazardous substances are used daily. These include for example disinfectants, surgical gases, drugs, and chlorine gases. There will be a release of these substances in larger quantities. The station is contaminated and needs to be evacuated. Patients and staff are directly at risk.
